Abstract

A hybrid mesh network is the most generic type of Wireless Mesh Networks (WMN) and is a combination of static mesh routers and mobile mesh clients. Static mesh routers are typically much less resource-constrained than mobile mesh clients, and are also often equipped with multiple radio interfaces. Furthermore, most of the traffic is directed to/from a gateway, as the mesh clients generally access services on the Internet or other networks. Thus, routing protocols need to distinguish the types of mesh node and take account of the traffic pattern in hybrid mesh networks. This paper proposes a Hybrid Distance Vector (HDV) routing protocol for hybrid mesh networks, which combines the tree-based routing strategy with the reactive routing strategy. Simulation results demonstrate that the proposed HDV routing protocol can outperform AODV and AODV-ST routing protocols in terms of the routing overhead, network throughput, and end-to-end delay in a hybrid mesh network.
