无线传感器网络中基于效用模型的分布式功率控制机制
A Utility Model-Based D istributed Power Control Sche me in Wireless Sensor Networks
摘要
Abstract
In this paper,the utility model is introduced into power control of wireless sensor network and a utility mod-el-based distributed power control scheme (abbreviated UMDPC)is presented.This scheme establishes the correspondence be-tween the transmission power of sensor nodes and utility model,and optimizes the link reliability and energy consumption with a unified network utility optimization (NUM)framework.Then this NUM problem is proved to be a convex optimization problem.A distributed optimization algorithm is proposed to calculate the optimal transmission power of each node by using dual decomposition techniques.Finally,experiments are performed to evaluate the performance of the proposed scheme.Simu-lation results show that UMDPC scheme can maximize network utility and improve energy utilization efficiency.关键词
