摘　　要：为了节省无线传感器网络中节点的能耗,延长网络的生命周期,提出一种在软件定义无线传感器网络中基于非合作博弈的拓扑控制算法。首先,基于软件定义架构设置网络模型。然后,提出一种非合作博弈拓扑控制算法,该算法由控制器基于全局信息为每个节点与其他节点进行博弈,博弈过程中综合考虑节点的剩余能量、传输功率和链路跳数,使每个节点都能找到最利于自己的发射功率,从而在保证网络连通的前提下延长网络寿命。仿真结果表明,所提算法与其他基于博弈论拓扑控制算法相比,各节点能耗更加均衡,延长了网络生命周期。In order to save energy consumption of nodes and prolong the life cycle of wireless sensor networks,a new topology control algorithm based on non-cooperative game in WSN is proposed.Firstly,the network model is set up based on software definition architecture.Then,a non-cooperative game topology control algorithm is proposed.The controller games with other nodes based on global information in this algorithm.In the process of game,the residual energy,transmission power and link hop number of nodes are considered comprehensively,so that each node can find the transmission power which is most favorable to its own,so as to extend the network life on the premise of ensuring network connectivity.The simulation results show that compared with other topology control algorithms based on game theory,the energy consumption of each node is more balanced,and the network life cycle is prolonged in this paper.
