Comparative Analysis of Link Quality Metrics and Routing Protocols for Optimal Route Construction in Wireless Mesh Networks
The authors provide a comparative analysis of various routing strategies that affect the end-to-end performance in wireless mesh networks. They first improve well-known link quality metrics and routing algorithms to enhance performance in wireless mesh environments. They then investigate the route optimality, i.e., whether the best end-to-end route with respect to a given link quality metric is established, and its impact on the network performance. Network topologies, number of concurrent flows, and interference types are varied in their evaluation and they find that a non-optimal route is often established because of the routing protocol's misbehavior, inaccurate link metric design, inter flow interference, and their interplay.
