| description | Interference is the main factor that leads to the decrease in network performance in wireless mesh networks (WMNs). In this paper, we propose a load-balance and interference-avoid partially overlapped channels assignment (LBIA-POCA) scheme aiming to improve network throughput by the cooperative management of interfaces and channels. This scheme first assigns the interfaces of the neighbor nodes by the Huffman tree-based centralized allocation algorithm. Second, the links are divided into M non-interfering link sets according to the interference model, which are respectively scheduled in M time slots. At last, more time slots are further assigned for the links without interference, increasing the number of links that can be scheduled per time slot. The simulation results demonstrate that the proposed scheme performs well in WMNs with hybrid traffic, especially in throughput and packet loss rate. |
