【Abstract】 On the basis of wireless Mesh network routing algorithm proposed in reference[10],an improved route forwarding algorithm based on utility forwarding was proposed to analyze the characteristics of different factors that affect the utility value under different network environments.According to the characteristics of different factors that affect the utility value under different network environment,the historical communication data of the nodes were used to obtain the weight value,so that the algorithm could better adapt to the real network environment.The network delay,node utility value and hops between nodes were comprehensively used to select the optimal next hop sending node to reduce unnecessary delay increase and waste of resources in the network.The ONE simulation experiment indicates that compared with other four routing protocols,the forwarding efficiency of data packets can be improved,and thus the performance of the network can be improved using the proposed algorithm.更多还原
