Abstract

In this paper we consider anycast routing for multi-gateway wireless mesh networks to maximize the overall quality of communications. For such networks, anycasting provides an effective mechanism to reduce problems due to congestion and interfence by appropriate selection of gateways, particularly at heavy traffic conditions. However, as proved in this paper, the optimal gateway selection problem is NP-hard. Hence, we propose a heuristic for route selection that tries to perform gateway and route selection to minimize interference. Simulation results show that our proposed anycasting scheme performs better than other well known anycasting protocols.
