The effective technique to avoid congestion and losses in networks is by multipath routing. Multipath routing constructs multiple paths for a source and destination and provides fault-tolerance and reliability. In IEEE 802.16 Wireless Mesh Networks (WMN), very little work has been done on multipath routing. Also traditional multipath routing protocols induce the flooding of control messages and congestion in gateways. In this paper, the authors propose a Reliable Multipath Routing (RMR) protocol for 802.16 wireless mesh networks.
