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
This brief provides an overview of recent developments in multi-hop routing protocols for Wireless Sensor Networks (WSNs). It introduces the various classifications of routing protocols and lists the pros and cons of each category, going beyond the conceptual overview of routing classifications offered in other books. Recently many researchers have proposed numerous multi-hop routing protocols and thereby created a need for a book that provides its readers with an up-to-date road map of this research paradigm. The authors present some of the most relevant results achieved by applying an algorithmic approach to the research on multi-hop routing protocols. The book covers measurements, experiences and lessons learned from the implementation of multi-hop communication prototypes. Furthermore, it describes future research challenges and as such serves as a useful guide for students and researchers alike.

Book Description
Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.

Book Description
In this thesis, we focus on routing protocols for Wireless Sensor Networks (WSNs). The main research problems in the domain of routing data packets in a multi-hop network are the optimisation of the energy and the routing under multi-criteria QoS constraints (e.g., energy, reliability, delay, ...). To address these problems, this dissertation proposes two contributions. Firstly, an optimal probabilistic routing protocol which balances the usage of energy and secondly, a routing protocol which is able to simultaneously take into account multiple QoS metrics. In fact, for balancing the energy consumption between the multiple existing links, the existing probabilistic routing protocols assign a probability to each link, either in an empirical way or depending on proportional energy level of the path. We did not know what are the optimal probabilities which lead to the optimal network lifetime. Our first contribution proposes optimal probabilities by modeling and solving a linear programming problem. As for the multi-constrainted QoS routing problem, multiple metrics are defined by RPL (a standard of IETF) but the existing protocols chose paths either according to only one metric or using a single aggregated function with multiple metrics, but never all the metrics simultaneously. In this dissertation, we first evaluate the performance of the operator calculus algebra introduced by R. Schott and S. Staples which defines an efficient algorithm allowing to find all the paths which satisfy the multiple constraints in a graph, and secondly we proposed a distributed version of this algorithm based on which a routing protocol has been designed. Both contributions are implemented in Contiki environment and simulated/emulated under Cooja (a software designed for simulating protocols of WSNs).

Book Description
Wireless Sensor Networks have a wide range of applications in different areas. Their main constraint is the limited and irreplaceable power source of the sensor nodes. In many applications, energy conservation of the sensor nodes and their replacement or replenishment due to the hostile nature of the environment is the most challenging issue. Energy efficient clustering and routing are the two main important topics studied extensively for this purpose. This book focuses on the energy efficient clustering and routing with a great emphasis on the evolutionary approaches. It provides a comprehensive and systematic introduction of the fundamentals of WSNs, major issues and effective solutions.
