A load-balance and interference-aware routing algorithm for multicast in wireless mesh network

With the rapid development of multi-media services, the multi-media traffic flows make the load in wireless mesh network (WMN) increase sharply, which incurs network congestion. In the context of having multiple multicast sessions, the load-balance and interference-aware (LBIA) routing algorithm is proposed by considering the intra-flow interference, inter-flow interference and load balance. This algorithm selects the link with less load to transmit information and uses the load balance factor to balance the load of each link in multicast sessions. NS3 simulation results show that the proposed algorithm can improve the overall network performance.
