无线多跳网络基于位势博弈的传输调度方法

摘要

To further increase the throughput of wireless multi-hop networks, this paper proposed a scheduling method based on potential game with physical interference model. It considered that the link rate could change in terms of SINR dynamically. By designing the potential function properly, the existence and convergence of the Nash equilibrium could be guaranteed. Meanwhile, the global function could be optimized while each player tried to minimize its payoff. Simulation results show that the method has good performance.%为了进一步提高无线多跳网络的吞吐量,采用物理干扰模型,考虑链路速率可以随信干噪比( signal to interference plus noise ratio,SINR)动态可调,提出了基于位势博弈的传输调度算法.通过设计合适的位势函数,使得纳什均衡点的存在性和收敛性都得到保证.同时,每个参与者在最小化自己支付的同时,使全局函数达到最优.仿真结果表明,该算法具有较好的吞吐量性能,而且有较快的收敛速度.
