This book was released on 2014 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless video sensor networks have been examined and evaluated for a wide range of applications including video surveillance, video tracking, computer vision, and remote live video and control. Reasons behind the importance of sensor nodes include ease of implementation, ability to operate in adverse environments, easy to troubleshoot and repair, and high performance levels. The biggest challenges with the architectural design of wireless video sensor networks are power consumption, node failure, throughput, durability, and scalability. The project at hand was to create a gateway node to integrate between an "internet of things" framework and a wireless sensor network. The Flexi-Wireless Video Sensor Node Platform (WVSNP) is low cost and low power, and compatible with traditional sensor networks in which the main focus is on maximizing throughput or minimizing node deployment. In this project, I addressed the challenges of video power consumption for wireless video sensor nodes. While addressing those challenges, I performed an analysis of predicting the node's durability when it is battery operated and to choose appropriate design parameters. I created a small optimized image to boot up Wandboard DUAL/QUAD board, capture videos in small/big chunks from the board. The power analysis was performed only for capturing scenarios, playback of reference videos, and live capturing and real timeplaying of videos on the WVSNP player. Each sensor node in the sensor network is battery operated and runs without human intervention. Thus, to predict node durability for different video size and format, I collected power consumption results. Based on these results, I have provided recommendations for HW/SW architecture.

This book was released on 2015-08-20 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Video Sensor Network (WVSN) is one type of Wireless Sensor Network (WSN), where each sensor is equipped with a camera component to capture videos, in addition to a processing component to process the captured videos before transmission. Many applications of WVSNs are widely used, such as surveillance applications that monitor and prevent harmful events, environmental tracking, and health monitoring applications.This work studies the problem of minimizing the total power consumption in a clustered based WVSN by proposing a cross-layer design to optimize the encoding power, the transmission power, and the source rate at each sensor node. The resource allocation is incorporated into a minimization problem, which takes into account the video signal distortion due to compression and packet losses in the wireless channel while trying to allocate network resources amongst multiple video sensors, such that the total power consumed in both compression and communication is minimized. For efficient communication, energy harvesting capability is added, where sensor nodes in the network are allowed to use renewable energy sources to contribute in green communication.

Download or read book Cross layer Design for Wireless Ad Hoc Sensor Networks written by Xinsheng Xia and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cross-layer design is an efficient approach to enhance energy efficiency and Quality of Service (QoS) in wireless ad hoc sensor networks. This dissertation will focus on the cross-layer issues and approaches. It will also discuss the latency-aware and energy efficiency tradeoffs and the packets transmission in the rear part of the dissertation. Firstly, we will analyze the cross-layer design for wireless sensor networks based on the virtual MIMO techniques. We will coordinate the physical layer, the MAC layer and the network layer for cross-layer evaluation. Performance analysis and simulation results show that throughput and packet loss ratio will have different performances compared with only considering the MIMO scheme in the physical layer as the increase of the number of transmitters. Secondly, we will discuss the bottom-up optimization for cross-layer design. We used the fuzzy logic system (FLS) to coordinate the physical layer, the data-link layer and the application layer for cross-layer design. Simulation results show that the cross-layer design can reduce the average delay, increase the throughput and extend the network lifetime. The network performance parameters could also keep stability after the cross-layer optimization. Thirdly, we extended the FLS application in cross-layer design from Type-1 to Type-2. We demonstrated that type-2 fuzzy membership function (MF), i.e., the Gaussian MFs with uncertain variance is most appropriate to model BER and MAC layer service time. We used the forecasted transmission delay to adjust the transmission power, and it showed that the interval type-2 FLS performed much better than a type-1 FLS, and FLSs performed better than back-prop NN in terms of energy consumption, average delay and throughput. Also, we obtained the performance bound based on the actual transmission delay. Finally, we applied a image as the real service in WSNs. We considered cross-layer design for image transmission in WSNs. We combined the application layer, the MAC layer and the physical layer together. According to analysis and simulation, there were tradeoffs between QoS and energy consumption for both high priority service and low priority service. Application level QoS was applied to evaluate the cross-layer design for WSNs. Two other works were discussed in this dissertation. One is the latency-aware and energy efficiency tradeoffs for wireless sensor networks. Latency and energy efficiency are two important parameters to evaluate the WSNs. The FLS is applied to the nodes selection. In contrast with the cases that only consider one descriptor, the FLS application can manage the delay/energy tradeoffs to meet the network performance requirements. Another work discussed is "Packets Transmission in wireless sensor networks: interference, energy and delay-aware approach". In the WSN, the interference will affect the packets transmission. We proposed FLS in the optimization of SIR threshold selection. Average delay and distance of a node to the source node are selected as antecedents for the FLS. The output of FLS provided adjusting factors for the SIR threshold. Simulation results showed the fuzzy optimization could achieve a better network efficiency, reduce the average delay and extend the network lifetime.
