Abstract

Wireless mesh networks (WMNs) will play an important role in the next generation wireless communication systems because it can support broadband services with ubiquitous coverage by low transmission power. However, the question will be caused by using the shortest path routing protocol such as DSR and AODV in such multi-hop networks. Load unbalance of nodes will sharply degrade the traffic quality in WMNs. In this paper, we put forward a traffic load model considering the interference among wireless nodes. By using the probability of channel busy as the load of a node, we propose a load balanced routing scheme based on AODV. Simulation results show that interference-aware load balanced routing (IALBR) achieves significant traffic quality enhancement over basic IEEE 802.11 mesh networks.
