Performance Enhancement of AODV Routing Protocol in Wireless Mesh Networks

Abstract— Performance of routing protocols mainly depends on efficient channel path establishment, route optimization and control overhead. Route optimization plays a pivotal role in self-healing” and “self-configuring” wireless mesh networks (WMN). State-of-the art routing protocols rely on IEEE 802.11 MAC and TCP congestion control mechanisms to optimize the performance of routing protocols. Since, traditional end-to-end TCP is designed for network congestion, it is difficult to identify route failure due to node mobility and buffer overflow. In addition, IEEE 802.11 MAC works on link connectivity which takes relatively long time to recover end-to-end route path. Hence, it is important to design a congestion control mechanism at the network layer to enhance the performance of routing protocol during mesh client handover. In this paper, Active Queue Management (AQM) is implemented in the network layer to avoid congestion due to buffer overflow and client mobility. Simulation results (NS-2) show that proposed AQM based routing protocols are outperformed compared with the existing routing protocols in wireless mesh networks.

Index Terms— Route optimization, congestion control, packet buffering.
