GSQAR: A Quality Aware Anycast Routing Protocol for Wireless Mesh Networks

We consider anycast routing to improve the quality of communications in multi-gateway wireless mesh networks. A centralized gateway and route selection scheme is proposed that tries to maximize the end-to-end probability of success and minimize the end-to-end delay of all active traffic flows in the network. The proposed scheme employs a novel route quality metric that is based on the effects of interference on data packet transmissions. We present performance evaluations of the proposed scheme using ns-2 simulations.
