Multipath routing based adaptive multi-channel MAC protocol for wireless mesh networks

In this paper, we propose an anycast mechanism which can adaptively choose the best next-hop to forward packets during the announcement traffic indication map (ATIM) window of multi-channel medium access control (MMAC) protocol. In order to improve the performance of networks by reducing transmission retries and packet drop probabilities, we also propose a multipath extension of AODV routing protocol to provide the adaptive MMAC protocol with multiple next-hop links. Simulation results show that the proposed scheme provides better performance, both in regular and random scenario of mesh network model.
