| 摘 要： | 为降低水声传感器网络低带宽、高延迟的特性对介质访问控制(MAC)层性能的影响,提出一种基于进化博弈论的MAC协议。该协议中,每个传感器节点可以采用空间复用和时间复用两种策略,并利用复制动力学方程得到进化稳定策略,达到进化稳定均衡,提高信道利用率和数据传输效率,进而实现MAC协议的性能优化。仿真实验结果表明,与传统的水声传感器网络MAC协议相比,基于进化博弈论的MAC协议可以提高网络吞吐量以及数据包发送成功率。

| Abstract: | In order to decrease the influence caused by low bandwidth and high latency on Media Access Control (MAC) layer in Underwater Acoustic Sensor Network (UWASN), an Evolutionary Game Theory based MAC (EGT-MAC) protocol was proposed. In EGT-MAC, each sensor node adopted two strategies including spatial multiplexing and temporal multiplexing. With the replication kinetics equation, each strategy got an evolutionary stable strategy and reached stable equilibrium of evolution. In this way, it improved channel utilization rate and data transmission efficiency to achieve performance optimization for MAC protocol. The simulation results show that EGT-MAC can improve the network throughput as well as the transmission rate of data packet. |
