摘要

无线体域网未来将在医疗、运动、休闲和生活等方面起着越来越重要的作用。解决无线体域网的2个关键问题：第一是在每个时隙内选择哪一个传感器节点传输来最大化网络的生存期，确保网络的公平性；第二是在未降低可靠性的前提下，选择合适的发射功率等级达到节省能量的目的。针对第一个问题，提出一种分布式调度算法去均衡无线体域网的生存期和公平性；针对第二个问题，提出改进的传输功率控制算法自适应地校正传输功率。仿真结果验证了所提出算法的有效性。

Abstract

Wireless body area networks(WBAN)were expecting to play an essential role for healthcare

sports

leisure

and all the aspect of our daily life.The purpose was to solve two key issues of WBAN.The first issue was which sensor should transmit during each time slot in order to maximize the lifetime as well as maintaining fairness performance.The second issue was which transmit power level should be chosen for the purpose of energy saving without degrading reliability.For the first problem

a distributed scheduling algorithm was proposed to balance lifetime and fairness for WBAN.For the second issue

a modified transmission power control algorithm was presented to adjust transmit power adaptively.Simulation results are presented to demonstrated efficacy of the proposed algorithm.
