摘要:
 无线传感器网络中的节点能量有限、工作环境复杂,易导致节点能量消耗不均,节点耗能不均将极大地缩短网络生命周期.针对无线传感器网络中节点能量有限和耗能不均问题,建立了一种基于马尔可夫博弈的功率控制模型.该模型引用分簇结构,确定研究对象为簇头节点;引入多信道技术,不同信道使用不同概率调节各自簇头节点的发射功率来降低节点之间的相互干扰,进行节点功率优化;通过迭代方式进行功率和概率补偿,求解功率控制模型中的纳什均衡,使节点发射功率达到最优,达到整个网络节点能量的均衡消耗,延长网络生命周期.仿真结果表明,该模型在网络节点能量消耗的均匀程度、加强节点之间的合作、减少节点间信道竞争和延长网络生命周期上都有显著效果.
Abstract:
 It can result in imbalance of energy consuming and shortening of network life that limited energy and complex work environment of network nodes in wireless sensor network.Aiming at limited energy and imbalance of energy consuming in wireless sensor networks,the power control model is constructed based on Markov game.Referencing cluster structure,research object are cluster head nodes.Then introducing multi-channel technology,the node power can be optimized through using different probability to adjust transmit power with different channel to reduce mutual interference between nodes.Method of adopting iteration computation is used to compensate transmitting power and probability to obtain the Nash equilibrium,to optimize node transmitting power,to balance network nodes energy consumption and prolong left-time of the network.The experimental results show that the model can effectively improve the uniformity of energy consumption of network nodes,strengthen cooperation between nodes,reduce node channel competition and prolong left-time of the network.
