Book Description
Abstract: Wireless sensor networks (WSNs) have secured a role in many emerging applications spanning environmental, ecological, industrial, and commercial domains in which data are periodically sourced from sensors and used in monitoring and control. The ubiquity of network-based video streaming, largely in the form of monitoring equipment installed in administrative domains (cities, campuses, offices, highway systems) has been possible by increases in capability of low-cost cameras and computational devices. However the streaming of video data over wireless sensor networks has the nature of heavy data transmission load, relatively long data transmission period, severe inter- and intra-path interference, and unbalanced network energy consumption under severe energy constraints. These characteristics make it very difficult to achieve meaningful throughput performance for video data delivery over WSN. In this dissertation we focus on the development of practical throughput aware video data routing techniques optimized to data delivery cost to address the challenge of QoS support in end-to-end throughput achievement for bandwidth demanding video delivery in a large-scale, battery-operated sensor network. We utilize video data streaming throughput as the main metric to quantify the video delivery performance. We present a benchmark data routing algorithm to assure the throughput performance (QoS) of a data path via eliminating the impact of inter-path interference through path isolation. Extending the benchmark algorithm, we develop an interference-tolerant data routing algorithm to improve the general data egress rate of the entire network with some tolerant sacrifices of the throughput performance on each stream. The routing algorithms construct throughput-guaranteed end-to-end video delivery data paths based on accurate video delivery performance estimation. We present two analytical models in conjunction with simple proactive admission and congestion control strategies to enable accurate end-to-end data delivery throughput estimation with considerations of data stream's transmission rate, location, and relative positions. Simulations demonstrate that our estimation models are highly consistent with the measurement of the real data transmission scenario and our proposed data delivery scheme adapts to the optimal data rate about three times faster than a traditional CTS/RTS scheme without generating any jitter as observed in CTS/RTS. In addition, we exploit the option of deploying mobile base stations to support improved video delivery QoS. The proposed mobile base station deployment strategy improves the video delivery performances with the best effort to minimize the data delivery cost. As a complementary solution for the deployment of our routing scheme over WSNs, we develop a new code dissemination framework for generic WSN applications. Simulation and prototype implementation illustrate that our framework is almost five times faster for application code dissemination than traditional over the air programming strategy. Another contribution of this dissertation is the constellation graph of routing algorithms. It presents a clear way of selecting the most appropriate routing algorithm for a specific WSN application.

Book Description
In Mobile Ad hoc Networks (MANETs), mobile nodes communicate over an error prone wireless channel without any centralized control. MANETs have n9 fixed topology because mobile nodes can freely join or leave the network at any time. As a consequence, it is difficult to guarantee Quality of Service (QoS) in these networks. The current routing , protocols provide only best effort services to the applications. Multimedia communications become very popular and require various types of QoS guarantee from the network such as guranteed throughput, bounded end-to-end delay. The QoS-aware routing (QA) and Admission Control (AC) protocols try to address the issue of QoS to some extent. In this work, a novel Flow Aware Admission Control (FAAC) protocol is designed to assure the guaranteed throughput to data sessions. It utilizes the route cache of routing protocol and devises a new admission technique to accept or reject data session to the network. It is partially coupled with the Oynamic Source Routing (OSR) protocol as it has used the basic functionality of route search of the OSR protocol. The protocol has two phases: (i) route discovery and (ii) test the route nodes resources for a data session entry. The performance evaluations show that the protocol outperforms the existing best effort routing and QAR and AC protocols such as OSR and Contention Aware Admission Control (CACP) protocols in providing QoS in MANETs. Mobility is a big challenge to assure guaranteed throughput to data sessions. To address this issue, we have designed F AAC-Multipath protocol that uses multiple routes for data transmission. The protocol maintains two tested routes for each data session and devises new fast switching mechanisms that switch the data flow from one route to another to guarantee the throughput. Multimedia applications require guaranteed throughput as well as bounded end-to-end delay. To address this issue we.have designed Flow Aware Admission Control-Multipath with Multiple constraints (F AAC-MM). This protocol assures the application with guaranteed throughput as well as bounded end-to-end delay. FAAC-MM switches the data flow from primary to secondary route on the basis of achieved throughput and end-to-end delay. We have also analyzed and compared the proposed protocols with the state of the art protocols such as CACP and Multi-path for Mobile Ad Hoc Networks. The simulation results show that our protocol outperforms the above mentioned protocols.
