Wireless Mesh networks have the potential to provide inexpensive and quick access to the internet for military communications, surveillance, education, healthcare and disaster management. This work caters to the growing high-bandwidth demands by providing low delay and high throughput by designing efficient, robust routing algorithms for wireless mesh networks. Chapters 2 and 3 of this dissertation describe adaptive routing algorithms that opportunistically route the packets in the absence of reliable knowledge about channel statistics and the network model. We design two adaptive routing algorithms, Distributed Opportunistic Routing (d-AdaptOR) and No Regret Routing (NRR), which minimize the expected number of transmissions and thus improving the throughput. The remainder of the dissertation concerns with the design routing algorithms to avoid congestion in the network. In Chapter 4, we describe a Distributed Opportunistic Routing algorithm with Congestion Diversity (ORCD) which employs receiver diversity and minimizes end-end delay. In Chapter 5, we present the Congestion Diversity Protocol (CDP), a distributed routing protocol for 802.11-based multi-hop wireless networks that combines important aspects of shortest-path and back-pressure routing to achieve improved end-end delay performance. This work reports on a practical (hardware and software) implementation of CDP in an indoor Wi-Fi testbed.

The focus of this brief is to identify what unifies and what distinguishes the routing functions in four wireless multi-hop network paradigms. The brief introduces a generic routing model that can be used as a foundation of wireless multi-hop routing protocol analysis and design. It demonstrates that such model can be adopted by any wireless multi-hop routing protocol. Also presented is a glimpse of the ideal wireless multi-hop routing protocol along with several open issues.

Wireless multi-hop networks have become an important part of many modern communication systems. Opportunistic routing aims to overcome the deficiencies of conventional routing on wireless multi-hop networks, by specifically utilizing wireless broadcast opportunities and receiver diversity. Opportunistic routing algorithms, which are specifically optimized to incorporate into the routing decisions a model of wireless transmission, take advantage of scheduling, multi-user, and receiver diversity gains and result in significant reduction in the expected cost of routing per packet. The ability of the algorithm to take advantage of the aspects of wireless transmission, however, depends on the scalability and the additional overhead associated with the opportunistic routing as well as the availability of side information regarding wireless channel statistics, topology, etc. This monograph sheds light on the performance gains associated with incorporating into the routing strategy the nature of wireless transmission. This monograph first provides an overview of various opportunistic distance-vector algorithms that have been developed to incorporate wireless transmission and routing opportunities. Furthermore, an optimal opportunistic distance metric is proposed whose performance is examined against the performance of several routing algorithms from the literature. The performance is examined first in analytical examples, then via simulation to identify the strengths of the optimal opportunist routing algorithm. To allow for a scalable and distributed solution, the distributed computation of this optimal distance-metric is provided. The performance of a distributed implementation of the optimal opportunistic routing algorithm is also examined via simulation. In addition to the construction of the opportunistic schemes in centralized and distributed fashions, this monograph also addresses how learning the wireless medium can be efficiently incorporated in the structure of routing algorithm. Finally, this monograph examines the dynamic congestion-based distance metric and its performance against other congestion aware solutions in the literature.

Ad hoc networking research has received considerable attention in recent years as it represents the next phase of networking evolution. Efficient and reliable routing of data from the source to destination with minimal power consumption remains the crux of the research problem. Fading mechanisms inherent in wireless communications can impact the packet routing mechanisms in these types of networks. In this thesis, we develop a mathematical framework for evaluating several network diversity schemes that take advantage of the random nature of fading to provide/ enhance the network performance. The efficacy of these different network diversity mechanisms are examined in slow-fading, frequency non-selective Rice and Nakagami-m multipath fading channels. Performance metrics such as the end-to-end outage probability and the end-to-end average symbol error rate are studied in the analysis of these types of networks with the proposed network diversity schemes. Numerical results reveal that the proposed schemes can offer significant power efficiency improvement in a variety of operating scenarios of practical interest.

Cooperation is then applied to end-to-end multi-hop routes by using a relay if available for each hop along the end-to-end route. Performance improvements in terms of saturated throughput and end-to-end delay are evaluated for static predetermined routes. COBRA MAC is then combined with dynamic routing protocols like AODV and OLSR when a single transmission rate is used. Relay selection and performance improvements obtained under such conditions are then presented. Since, a typical IEEE 802.11 based network has multiple transmission rates, rate selection for the relay becomes important. Hence, heuristics to perform rate selection for relays are presented. Finally, a metric that jointly optimizes the end-to-end route and relay selection in a multi-hop network is proposed. Using analysis and simulations, it is shown that opportunistic cooperation provides noticeable performance improvements when applied to a multi-hop network.
