| 摘 要： | 研究了水下无线传感器网络随机布放条件下的连通性覆盖问题.针对节点通信半径小于2倍的感知半径时,不能达到连通性要求的问题,给出一种连通性最差情况下(通信半径等于感知半径),连通性覆盖算法唤醒机制.唤醒机制中,充分考虑能量以及节点之间的距离信息来选择进入工作状态的最佳节点,使得网络在满足覆盖性要求的基础上,保证了节点之间的连通性要求.最后通过仿真分析,验证方法有效性.

| Abstract: | The connectivity and coverage for t he random dist ributing wireless sensor node in underwater arest udied. Aiming at t he problem t hat t he wireless sensor network is disconnected when t he communicationradius is less t han the twice of apperception radius , an arousing scheme which adapt to the wor st condi2tions is proposed. In t his scheme , the energy and distance information between different nodes are consid2ered to select t he best sleeping node which t urn into active state. It satisfied the needs for connectivity andcoverage ability. At the last , numerical simulation result s are presented to illust rate t he efficacy of thisscheme. |
