Abstract: Wireless mesh networks have fixed nodes, but a large number of mobile nodes still have energy, bandwidth, memory, and other restrictions. In opportunistic routing protocols, data packets from source nodes to destination nodes, need to be forwarded by relay nodes opportunistically. However, due to node restrictions itself, nodes are often reluctant to accept the forward request. Selfishness in non-cooperation among nodes is the main reason for the decrease of network throughput. To solve this problem, the concept of cooperation degree evaluation function is proposed. And a repeated game model of CGTFT strategy nodes based on evaluation function of cooperation is established. The simulation result shows that the model can effectively suppress selfishness and incentive cooperation and improve networks throughput.
