A Load-Balanced Coding-Aware Multicast Routing in Cognitive Wireless Mesh Networks

Cognitive wireless mesh networks use network coding techniques can improve the transmission performance. Thus, a new load-balanced routing measure CRM-LB(Coding-aware Routing Metric with Load Balancing) based on network coding was presented, the CRM-LB increase of the considerations of traffic concentration level congestion level all nodes on the path P based on CRM(Coding-aware Routing Metric). Further proposed cognitive wireless mesh networks multicast routing CLR(Coding and Load-balancing Routing) based on the CRM-LB. The protocol can increase network coding opportunities, taking into account the network load balancing. The performance analysis and simulation results show that the protocol, under the premise of improving throughput, not only to better support network coding, and to achieve load balancing in network.
