WSN中基于博弈论的节点功率控制算法
Based on game theory algorithm in nodes power control of WSN
摘要
Abstract
In this paper, game theory is applied to the WSN power control to reduce the energy consumption of the point transmission and prolong the lifetime of the network. The utility function is constructed by considering the residual energy and the transmitted power of the node. The remaining energy larger node is as the next hop node, which connects other nodes and takes more transmission tasks. In the communication process, the nodes take power control game algorithm as strategy and constantly adjust their strategies to improve the accuracy of information transmission. Nash equilibrium is proved to exist in the algorithm. Simulation results show that this algorithm can realize the purpose of reducing the energy consumption of wireless sensor network through the control of node transmission power, calculating the optimal transmit power faster, and getting the higher signal interference ratio compared with traditional distributed power control algorithm.关键词
