多跳水下传感器网络中的功率分配算法

摘要

Underwater wireless sensor networks are emerging as an active research. The main challenges are the constraint of energy and limitation of rate. Parameter estimation is a frequently encountered problem. This paper analyzes the performance of the incremental distributed estimation scheme, and presents a power scheduling scheme which minimizes the total power consumption while ensuing a given performance.%水下无线传感器网络的研究越来越受到学术界的重视,其典型特点是能量和带宽有限.多数水下无线传感器网络的应用都可以归结为参数估计问题.本文针对多跳水下无线传感器网络,对递进式的分布式参数估计算法进行了性能分析.在此基础上,利用交替最小化方法得到功率分配方案,目标是在给定的均方误差性能要求下,使得网络消耗的总功率最小.
