摘要 将信道竞争过程建模为非完全信息动态博弈,解出此博弈的纳什均衡。在无线传感器网络媒体接入控制协议S-MAC的基础上,根据求得的纳什均衡,提出IIDG-MAC协议。仿真结果表明,与S-MAC相比,IIDG-MAC可以提高分组发送成功率,降低分组重传能耗、发送时延和比特丢弃率,提高系统吞吐量。 The channel contention process is modeled as a dynamic game with incomplete information, and Nash Equilibrium(NE) of the game is obtained. Based on S-Medium Access Control(MAC) protocol for Wireless Sensor Networks(WSN), the IIDG-MAC protocol is proposed by using NE. Simulation results indicate that compared with S-MAC, using IIDG-MAC increases the successful transmission rate of packets, decreases energy consumption for retransmitting packets, delay and bit-drop-rate, and increases the system throughput.
