层次型WSN中基于博弈论的能耗优化与接纳控制机制

摘要

Energy constraint of cluster heads is an important issue in hierarchical wireless sensor networks.This paper proposed an admission control scheme based on a non-cooperative game model to solve the problem. By defining a pricing factor in the utility funct%针对层次型无线传感器网络中簇首节点的能量受限问题，提出了一种基于非合作博弈模型的节点接纳控制机制。该机制依据簇首节点的效用函数，引入定价因子，优化了簇首数目和功率水平，并得到簇首发射功率的纳什均衡。仿真实验模拟该博弈的均衡过程，将簇首节点设为非合作博弈的参与者，对各簇首节点发射功率的决策过程进行验证。
