摘要:

利用智能终端的协作转发可以缓解海量传感器数据的承载压力。然而,由用户携带智能终端的非合作行为会使转发性能急剧下降。为此,提出了一种带有协作意愿感知的边缘协作中继机制,以提高中继选择的合理性和激励机制的有效性。通过分析用户对转发数据的兴趣度感知用户的主观协作意愿,并考虑用户能量和缓冲的影响,综合选择协作状态最佳的用户作为中继。为了进一步激励中继用户参与协作转发,提出了一种基于讨价还价博弈的激励机制,充分地激励中继用户的客观协作意愿。仿真结果表明所提机制与其他中继机制相比,转发成功率和平均吞吐量分别提高了至少19.4%、17.9%,平均传递时延降低了至少18.6%。

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%.
