Abstract

The aggregate capacity of wireless mesh networks can be increased by the use of multiple channels. In this paper, we present the joint channel assignment implementation for Multiinterface and Multi-channel wireless network. To reap the full performance potential of this architecture, we propose and evaluate a combination of centralized and dynamic peer oriented distribution channel assignment, and enhanced AODV routing algorithms for Real Time multi-channel wireless mesh networks. Simulation results show that with joint channel assignment, equipping every wireless mesh network node with different interfaces operating on different channels can improve the total network performance and make the most of traffics by finding more routes with enhanced AODV.
