Wardrop Routing in Wireless Networks

Executive Summary

Routing protocols for multi-hop wireless networks have traditionally used shortest-path routing to obtain paths to destinations, and do not consider traffic load or delay as an explicit factor in the choice of routes. The authors focus on static mesh networks, and formally establish that if the number of sources is not too large, then it is possible to construct a perfect flow-avoiding routing, which can boost the throughput provided to each user over that of shortest-path routing by a factor of four when carrier sensing can be disabled, or a factor of 3.2 otherwise. So motivated, they address the issue of designing a multipath, load adaptive routing protocol that is generally applicable even when there are more sources.
