Abstract

On the basis of the existing routing algorithms of wireless Mesh networks, this paper proposed a new network coding algorithm based on utility forwarding to solve the problems caused by the dynamic variability and difference of networks. Firstly, it used the historical communication data between nodes to obtain the weight values of the factors that affected the utility value under different network environments dynamically. Then, it performed 2D random linear network coding at the cluster head nodes and sink nodes, and combined the remaining energy, utility value and packet loss rate of the nodes to determine whether the nodes could encode or not. And it used the strategy of coded packet first transmission to transmit the packets. Finally, it employed the network delay, the utility value and the number of hops between nodes comprehensively to select the optimal next-hop forwarding node. The simulation results show that this algorithm can improve packet forwarding efficiency, reduce transmission delay and improve network performance.
