Abstract
Hybrid wireless mesh networks are multi-hop networks consisting of two types of nodes, mesh routers and mesh clients. Mesh routers are more static and less resource constrained than mobile mesh clients, and form the wireless backhaul of the network. Routing in hybrid wireless mesh networks is a challenging task as both type of nodes participate in the routing and forwarding of packets. In this paper, we present extensions to the ad-hoc on-demand distance vector (AODV) routing protocol with the aim to exploit the heterogeneity of hybrid wireless mesh networks. As demonstrated via extensive simulations, our extensions achieve a more than 100% improvement over the standard multi-radio AODV in terms of key performance metrics such as packet delivery ratio, routing overhead and latency.
