Abstract:

The cooperative forwarding of smart terminals can relieve the load pressure of the massive sensor data. However, the non-cooperative behavior of the smart terminal carried by the user sharply reduces the performance of forwarding. For this reason, an edge cooperative relay mechanism is proposed with cooperative willingness aware to improve the rationality of relay selection and the effectiveness of the incentive mechanism. By analyzing the user's interest in forwarding data to aware the user's subjective cooperative willingness, and considering the impact of user's energy and buffer, the user with the best cooperation state is comprehensively selected as the relay. In order to further encourage relay users to participate in collaborative forwarding, an incentive mechanism based on the bargaining game is proposed to fully stimulate relay users' objective cooperative willingness. The simulation results show that compared with other relay mechanisms, the proposed forwarding success rate and the average throughput are increased by at least 19.4% and 17.9%, and the average transmission delay is reduced by at least 18.6%.

Key words: edge network, cooperative forwarding, relay selection, incentive mechanism
