A Routing Protocol for Wired-Gum-Wireless Ad Hoc Networks

Connecting infrastructure with ad hoc network enables expansion of communication area. Under this environment, two different type of route exist between nodes that belong to ad hoc network. One is the route using wireless links only. The other is the route using both infrastructure and wireless links. However, most of existing routing protocols select a route by minimum hop count from originator to destination, and do not consider differences of communication performance between infrastructure and ad hoc network. This paper proposes a new routing protocol for ad hoc network with infrastructure environment. The main feature of proposed routing is to use a simple formula to judge if a route using both infrastructure and wireless links is more effective than routes using wireless links only. The formula used for judging a route is introduced from results of throughput tests on simple network models. As a result of evaluation, proposed routing protocol improves throughput compared to AODV in high traffic situation
