▼ In recent years several studies have been conducted to establish a theoretical basis for the performance of molecular communication networks. The general aim of this thesis is to study the performance of diffusion-based molecular communication networks that use molecular circuits (i.e. a set of chemical reactions) at the transmitter or receiver, from a communication theory perspective.First we consider a diffusion-based molecular communication system where the transmitter uses Reaction Shift Keying (RSK) as the modulation scheme. We focus on the demodulation of RSK signals at the receiver, which consists of a front-end molecular circuit and a back-end demodulator. The optimal demodulator computes the posteriori probability of the transmitted symbols given the history of the observation. The derivation of the optimal demodulator requires the solution to a specific Bayesian filtering problem. Our key contribution is to present a general solution to this Bayesian filtering problem which can be applied to any molecular circuit and any choice of observed species. We present a few examples where we have applied this generalised solution to different receiver molecular circuits.We show that enzymatic reaction cycles (ERCs), a class of chemical reactions commonly found in cells and consisting of a forward and a backward enzymatic reaction, can improve the capacity of a molecular communication link. The technical difficulty in analysing ERCs is the nonlinear reaction rates. We deal with this by assuming that the amount of certain chemicals in the ERCs is large. To further simplify the problem, we use singular perturbation to study a particular operating regime of the ERCs. This allows us to derive a closed-form expression of the channel gain which suggests that channel gain can be improved by increasing the total amount of substrate in the ERCs. By using numerical calculations, we show that the effect of the ERCs is to increase the channel gain and to reduce the noise, which results in a better signal to noise ratio and in turn a higher communication capacity. Finally, we present a diffusion-based molecular communication system where both the transmitter and receiver are based on molecular circuits. By matching different transmitter and receiver circuit pairs we determine which combination of reactions at the transmitter and receiver yield better communication performance.

▼ In this research, we focus on two areas of video adaptation: video rate control and frame rate control. The first part is on video rate control, which aims to adjust video bitrate to meet the network constraint. To that end, we propose a joint source rate and congestion control scheme called video TCP-friendly rate control (VTFRC) that incorporates the video bit rate characteristic into the TFRC rate. VTFRC uses a frame complexity measure and the rate gap between the TCP and TFRC rates to opportunistically encode the video at a higher rate. Experiments show that VTFRC improves video quality over existing scheme while maintaining TCP-friendliness. However, VTFRC needs the encoder meet a target bitrate and provide a frame complexity measure. To do this, we propose a complexity-based rate control scheme using edge energy. We show that this scheme can describe the individual complexities of the frames without needing any information on the whole video. Experiments show that the scheme produces a video stream that is closer to the target bitrate while improving on its video quality over existing schemes.The second part of this thesis is on frame rate control, which aims to maximize the video quality and continuity using the frame generation rates. To approach this, we propose a frame rate optimization framework that characterizes the frame rate control problem and use Lyapunov optimization to systematically derive decoupled optimization policies. Results show that the framework reduces the prebuffering requirements significantly with a modest tradeoff in video quality.We then examine different ways of improving the frame rate optimization framework. Firstly, we reformulated the framework based on a discontinuity penalty virtual buffer, which is the cumulative difference between the receiving interval and playout interval. We show that this discontinuity penalty correlates to the discontinuity of the video and enables a wider range of frame quality functions to be used with the framework. Secondly, we introduce a constraint on the playout slowdowns using a virtual buffer that records the cumulative delays. Results show that this provides a superior tradeoff between the video quality and the delay introduced compared to the existing scheme. Lastly, we show how the optimization policies can be derived in the presence of feedback delays. Analyses show that the delayed feedbacks had a minimal impact on the optimization policies.

▼ Inspired by the spatial partitioning of receptors in the cell membrane, the general aim ofthis dissertation is to improve the performance of molecular communication links usingspatial partitioning. First, we consider a diffusion-based molecular communication linkassuming the receiver uses molecular circuits (i.e., a set of chemical reactions). Whenthe signaling molecules reach the receiver, they react with the chemicals at the receiverto produce output molecules. We consider the number of output molecules over time asthe output signal of the receiver. This output signal is stochastic because both diffusionand reactions are stochastic processes. If this output signal has high variance, then it canlead to degradation in communication performance. We investigate the effect of spatialpartitioning on the variance of the output signal. By modeling the diffusion and reactionusing linear noise approximation, we show that a spatially partitioned system gives a lowertotal output signal variance than one that does not use spatial partitioning, especially ina steady state. Second, we design a maximum a-posteriori demodulator filter for multiplereceiver voxels. This allows us to study the receiver behavior of different volumes andshapes. We propose two different types of receiver configurations: partitioned and mixed.We use Markovian approach to derive the demodulator filters for both configurations.These filters take the form of an ordinary differential equation which computes the logposterioriprobability of observing a transmission symbol given the continuous history ofreceptor activities. The key finding of this work is that spatial partitioning can be usedto reduce bit-error rate in diffusion-based molecular communications.Finally, we derive the molecular circuits to approximately compute the log-posterioriprobability for partitioned receivers. We show how this is done for two different types ofconcentration modulation schemes. By using simulation, we demonstrate that the outputof the derived molecular circuit is approximately equal to the log-posteriori probabilitycalculated by the exact demodulation filter if the log-posteriori probability is positive.Furthermore, we derive the demodulator that can decode a sequence of symbols by introducinga reset mechanism.

▼ Compressive sensing is a mathematical theory concerning exact/approximate recovery ofsparse/compressible vectors using the minimum number of measurements called projections.Its theory covers topics such as l1 optimisation, dimensionality reduction, informationpreserving projection matrices, random projection matrices and others. In this thesiswe extend and use the theory of compressive sensing to address the challenges of limitedcomputation power and energy supply in embedded systems. Three different problemsare addressed. The first problem is to improve the efficiency of data gathering in wirelesssensor networks. Many wireless sensor networks exhibit heterogeneity because of the environment.We leverage this heterogeneity and extend the theory of compressive sensingto cover non-uniform sampling to derive a new data collection protocol. We show that thisprotocol can realise a more accurate temporal-spatial profile for a given level of energyconsumption. The second problem is to realise realtime background subtraction in embedded cameras. Background subtraction algorithms are normally computationally expensivebecause they use complex models to deal with subtle changes in background. Thereforeexisting background subtraction algorithms cannot provide realtime performance on embeddedcameras which have limited processing power. By leveraging information preservingprojection matrices, we derive a new background subtraction algorithm which is4.6 times faster and more accurate than existing methods. We demonstrate that our backgroundsubtraction algorithm can realise realtime background subtraction and tracking inan embedded camera network. The third problem is to enable efficient and accurate facerecognition on smartphones. The state-of-the-art face recognition algorithm is inspiredby compressive sensing and is based on l1 optimisation. It also uses random projectionmatrices for dimensionality reduction. A key problem of using random projection matricesis that they give highly variable recognition accuracy. We propose an algorithm tooptimise projection matrix to remove this performance variability. This means we can use fewer projections to achieve the same accuracy. This translates to a smaller l1 optimisationproblem and reduces the computation time needed on smartphones, which have limited computation power. We demonstrate the performance of our proposed method onsmartphones. Advisors/Committee Members: Chou, Chun Tung, Computer Science & Engineering, Faculty of Engineering, UNSW, Hu, Wen, CSIRO.

▼ Depth sensors have appeared in a variety of embedded devices. This includes tablets, smartphones and web cameras. This has provided a new mode of sensing, where it is possible to record an image and the distance to everything in the image. Some pervasive computing applications have taken advantage of depth sensors, such as crowd sourced 3D indoor mapping. However, research into this area is still in its infancy, some questions remain before widespread adoption. These questions are: What kinds of applications can take advantage of depth sensor equipped embedded devices and the question of efficiently implementing algorithms on resource-constrained embedded devices?The purpose of this thesis is address these questions. We do so by presenting 3 prototype systems and accompanying lightweight algorithms. Each algorithm uses depth sensors to overcome problems in visual pattern matching and are lightweight enough to run on embedded platforms. We do this while achieving better results by several metrics compared to the current state of the art. These metrics include pattern matching accuracy, asymptotic complexity, run time and memory use.The first contribution of this thesis is QuickFind, for fast segmentation and object detection algorithm, it is applied to a prototype augmented reality assembly aid. We test it against two related algorithms and implement our prototype on a Raspberry Pi. The two related algorithms are: Histogram of Oriented Gradients (HOG), a popular object detection algorithm. Histogram of Oriented Normal Vectors (HONV), a state of the art algorithm specifically designed for use with depth sensors. Our test data is the RGB-D Scenes v1 dataset consisting of 6 object classes, in 1434 scenes of domestic and office environments. On our test platform QuickFind achieved the best results with 1/18 run time, 1/18 power use, 1/3 memory use compared to HOG and 1/279 run time, 1/279 power use, 1/15 memory use compared to HONV. QuickFind has a lower asymptotic upper bound and almost double the average precision compared to HOG and HONV.The second contribution of this thesis is WashInDepth, for fast hand gestures recognition, it is applied to a prototype to monitor correct hand washing. We test it against HOG, HONV and implement our prototype on a Compute Stick. WashInDepth is an extension of QuickFind. Segmentation is replaced with a background removal step. QuickFind features are used to perform hand gesture recognition, based on video recorded from a depth sensor. We test with 15 participants with 3 videos each for a total of 45 videos. WashInDepth achieved the best results with average of 94% accuracy and a run time of 11 ms. HOG achieved 86% average accuracy and 19 ms average run time. HONV achieved 88% average accuracy and 22 ms average run time. All 3 algorithms had average memory usage within 4 KiB of each other.The third contribution of this thesis is VeinDeep. VeinDeep performs identification using vein pattern recognition. We repurpose depth sensors for this task. As far as we are aware, it is the first… Advisors/Committee Members: Kanhere, Salil, Computer Science & Engineering, Faculty of Engineering, UNSW, Chou, Chun Tung, Computer Science & Engineering, Faculty of Engineering, UNSW.

▼ This thesis develops models to evaluate the impact of multi-modal sensor placement configurations on obtaining traffic parameters required for a variety of traffic monitoring and management applications.Existing traffic management strategies generally rely on the commonly used induction loop sensors, which are highly accurate presence detectors, however they have a limited sensing area. Alternate sensor modalities may provide a higher information gain in comparison, especially vision based sensors. An inherent problem with using vision based sensors in traffic management is the occlusion between vehicles, which can make detection of individual vehicles difficult.Information fusion from multiple sensors provides much richer information for scene understanding, leading to a greater ability to coordinate traffic management efficiently. Thus, effective sensor placement and fusion of data can improve the efficiency of traffic management. The aim of this thesis is to evaluate the impact of multi-modal sensor placement, and as a result improve the estimation accuracy of road traffic parameters obtained from various sensor configurations. More specifically, vision based sensors are studied, and later fused with inductive loops.In order to achieve this, models are developed to simulate various traffic flows, and to ensure consistency and relevance of the simulations to real world traffic. Models for single sensor modality and multi-modal sensor fusion are developed and are also validated. These models enable evaluation of sensor placement configurations to determine effectiveness for specific traffic applications.Results of various single sensor configurations demonstrate that the impact of view occlusion on the ability to detect vehicles can be improved by considering sensor placement. Combining inductive loops and video cameras by sensor fusion was found to overcome the problem of occlusion, resulting in a decided improvement in parameter estimation for traffic management and monitoring applications. For example, the sensor fusion models developed resulted in the queue length estimation accuracy being improved by up to 20%. Finally, by applying the models presented in this thesis to current ramp metering strategies, viable alternative sensor deployment solutions are recommended.

Besides the traditional mote-based sensing, the Participatory WSN paradigm allows people to sense their environment using readily available mobile phones, and share this information using existing cellular and Internet communications infrastructure.WSN is promising as it enables applications at affordable cost, which were not previously possible using the wired sensor networks. WSNs provide endless opportunities, but at the same time pose formidable challenges. One key challenge of WSNs is that the information collected by the wireless sensing applications is typically incomplete. For example, in the traditional WSNs, the amount of usable information is constrained by two key limiting characteristics, 1. limited energy availability to produce samples and 2. communication constraints. In the participatory WSNs, the amount of usable information is constrained by the uncertain availability of samples. Due to this incompleteness of information, it is not possible to “accurately” recover a phenomenon using WSNs.In this dissertation, we propose and design systems based on sparse recovery or sparse approximation methods to accurately recover various phenomena using the incomplete information collected by the wireless sensing applications. Due to the high level of temporal-spatial correlations amongst the data collected at the sensor nodes, the signal acquired the signal acquired by the sensor nodes is sparse or compressible. The sparsity or compressibility of the signal motivates us to apply sparse approximation methods, since such methods recover the sparse or compressible signals using significantly small amount of information.In order to validate our proposition, we case study three wireless sensing applications: rainforest monitoring, participatory noise mapping and object tracking. We design three systems: EAST (Energy Aware Sparse approximation Technique), Ear-Phone (End-to-End Participatory Noise Mapping System) and AACAT (Adaptive Algorithm for Compressive Approximation of Trajectory) based on different sparse approximation methods to accurately recover the sensed phenomena using a small amount of information collected by wireless sensing applications: rainforest monitoring, participatory noise mapping and object tracking, respectively. Our analysis and experimental results demonstrate that the proposed systems can accurately recover the phenomena subject to the small amount of information collected by the wireless sensing applications.

▼ Embedded sensing aims to use low-cost computing, sensing and communication components to realise various sensing tasks. Embedded sensing has been successfully used in different applications. Large amounts of sensing data contain abundant information, but create huge overheads for the resource-limited embedded nodes. Furthermore, interference from other sources also brings noise, which decreases the sensing performance. In this thesis, we apply Sparse Approximation-based Classification method (SAC) and electronically switched directional (ESD) antennas to address the challenges of the limited amount of resources in embedded systems and interference. Three different problems are addressed. The first problem is to reduce the overhead of real-time classification on Acoustic Sensor Networks (ASNs). The main challenges of in-network classification in ASNs include effective feature selection, intensive computation requirement and high noise levels. To address these challenges, we propose a sparse representation based featureless, low computational cost, and noise resilient framework for in-network classification in ASNs, which makes the computation feasible to be performed on resource constrained ASN platforms. The second problem is to make radio-based device-free activity recognition robust to radio frequency interference (RFI). Device-free activity recognition has the advantage that it does not have the privacy concern of using cameras and the subjects do not have to carry a device on them. Recently, it has been shown that channel state information (CSI) can be used for activity recognition in a device-free setting. We investigate the impact of RFI on device-free CSI-based location-oriented activity recognition. We propose a number of SAC-based fusion methods to mitigate the impact of RFI and improve the location-oriented activity recognition performance. The third problem is to reduce the impact of multipath propagation for radio tomographic imaging (RTI) . RTI enables device-free localisation of people and objects in many challenging environments and situations. However, the localisation accuracy of RTI suffers from complicated multipath propagation behaviours in radio links. We propose to use inexpensive and energy efficient ESD antennas to improve the localisation accuracy of RTI. We implement a directional RTI system to understand how directional antennas can be used to improve RTI localisation accuracy.

▼ This thesis aims to examine the efficiency of opportunistic multicast routing in Wireless Mesh Network (WMN). Specifically, an opportunistic multicast routing protocol has been developed in this work in order to gain better performance in WMNs compared to traditional multicast routing protocols. The number of transmissions in the network to deliver a packet from a source to group of destinations has been taken as measure for the performance of the protocol. Less number of transmissions in the network to deliver a packet to group of destinations is an indicator for a better performance.The work has been divided into two parts. In the first part, a proposal of the first version of opportunistic multicast routing protocol (OMRPv1) will be explained. By calculating the expected number of transmissions in the network, the efficiency of the protocol will be examined. OMRPv1 will be compared against a traditional protocol, non-opportunistic protocol, to confirm its better performance in the network. Then, a second version of our protocol will be introduced, OMRPv2, as a solution for some problems encountered in the first version. The comparison between OMRPv1 and OMRPv2 will show the better performance achieved with the newer version.In the second part, QualNet simulator will be used to simulate the protocol OMRPv2. In this part, not only the number of transmissions in the network will be considered, but also other metrics like end to end delay and delivery rate will be taken into account. The overhead of the protocol will be examined as well. Observation of the results from the simulation will lead to the third version of the protocol (OMRPv3). OMRPv3 will be simulated as well to show the improvement in the performance over the previous version OMRPv2.Finally, OMRPv3 will be compared to the best opportunistic multicast routing protocol in the literature, Beacon-less Geographic Routing for Multicast Applications (BRUMA). For that reason, BRUMA will be simulated in QualNet as well. For fair comparison, few modifications will be added to BRUMA. Then, the two protocols will be compared to each other using many metrics. Delivery rate, end to end delay, and number of transmissions in the network to serve the multicast groups are some of the metrics that will be used to compare the two protocols. Results show that our protocol, OMRPv3, outperforms BRUMA in many of these metrics. Advisors/Committee Members: Chou, Chun Tung, Computer Science & Engineering, Faculty of Engineering, UNSW.

▼ The wireless mesh network (WMN) is a promising technology for deploying wireless infrastructure to provide users with always-on-line service anywhere anytime. In the future, high-speed wireless meshes will enable a whole new range of exciting multicast applications, such as IP-TV and video on demand. When implementing multicasting in a WMN, reliability becomes one of the major issues because: (1) the failure of nodes or wireless links may disrupt the multicast transmission, and (2) the lossy nature of radio communication causes random packet loss in wireless links. In this thesis, our main objective is to develop effective and efficient algorithms for reliable multicast in WMNs with a minimal consumption of network resources. More specifically, we focus on protecting multicast sessions from the above two categories of faults, node or link failure and opportunistic packet loss.The first contribution of this thesis is the design of a resilient forwarding mesh (RFM) to protect a multicast session from a link or node failure. An RFM effectively establishes two node-disjoint paths for each source-destination pair. An optimal resilient forwarding mesh (ORFM) is the RFM with the minimum number of transmissions, by utilising wireless broadcast advantage. We provide integer linear programming (ILP) formulations and several heuristic algorithms to find approximate solutions to the ORFM problem. Our simulation results show that a resilient forwarding mesh can provide "1+1" protection to the multicast session with limited additional overhead compared with a single multicast tree.The second contribution of this thesis is the comprehensive solution on reliable multicast in single rate WMNs against opportunistic packet loss. We first design a novel multicast routing metric called the expected multicast transmission (EMT). EMT captures the effects of opportunistic link packet delivery ratio, MAC layer retransmission and wireless broadcast advantage at the same time. The EMT of a MAC layer multicast transmission is defined as the expected number of data transmissions (including retransmissions) required for a packet to reach all the recipients. The objective of multicast routing is to build a multicast tree with the minimum total EMT for all transmitters (including the source node and all forwarders). We prove that this minimum EMT tree problem is NP-complete and provide ILP formulations, as well as a Lagrangian relaxation solution to reduce the computation time. In order to solve the problem in polynomial time, we design one centralised algorithm with the performance bound analysis and a distributed multicast protocol, probabilistically reliable on-demand multicast (PROD). The simulation results show that the minimum EMT multicast tree (MMT) formed by PROD outperforms shortest path tree and minimum forwarder tree in terms of packet delivery ratio and transmission overhead.The third contribution of this thesis is the low latency reliable multicast routing by utilising the rate diversity feature in wireless transmission.

▼ There has been an exponential increase in the deployment of wireless networks that operate in the unlicensed band, such as the IEEE 802.11 Wireless Local Area Networks (WLANs) and the Wireless Mesh Networks (WMNs). These networks do not require any additional regulatory approval before deployment and co-located networks often belong to different managing entities. Due to their use of the unlicensed band, no single network can claim exclusive use of a channel. Interference may subsequently arise, leading to suboptimal performance. Besides Medium Access Control (MAC) protocols, radio resource control schemes like channel allocation, power control and link adaptation have been proposed to reduce this interference. In this thesis, we are interested in the coexistence issues of such independent unlicensed band networks. Due to the autonomous nature of these networks, they may not cooperate or even use the same MAC protocol. We investigate the use of radio resource control schemes to improve the performance of such co-located networks. Our proposed schemes make use of utility-based techniques that are derived from game theory and optimization theory.We first model the interactions as a non-cooperative game and study the characteristics of the resultant game. We develop channel selection schemes for respectively, independent multihop WMNs and single-hop WLANs that are located together. We show that our proposed schemes improve the performance of non-cooperative WMNs by as much as 36%. In WLANs, our schemes show as high as 30% increase in aggregate throughput when evaluated against two existing channel selection schemes. Subsequently, we investigate how non-cooperation affects the solution of a cross-layer resource allocation algorithm designed for multi-radio, multi-channel, multihop wireless networks. We show that in the presence of non-cooperative networks, there exists efficiency loss due to the incomplete information of the contention environment. As a result, we propose an adaptation to the algorithm that is shown to improve performance by up to 3.2 times for a general physical/link layer model and 21% for a more realistic CSMA model.
