Abstract: We proposed a load balancing routing protocol in the wireless mesh network based on neural network prediction model,namely NNP-L2MPM.In this protocol,the optimal next hop to the destination is selected by using the path quality which is calculated by HELLO packets flooded on the network.The traffic load is measured by the length of the queue at the interface in MAC layer.Then the RBF neural network model is used to forecast the traffic load in the nodes of the mesh network.According to the forecasted traffic load in the next time,path quality is optimized,routing is updated previously,congestion in the intermediate nodes is avoided,and finally network performance is improved.Compared with the original routing protocol,the results of simulation show that the rate of the packet delivery can increase about 9%,and the average end-to-end delay can reduce about 16%.
