摘要 在无线传感器网络中,在使用合适的覆盖控制算法、保证一定覆盖性的前提下,使一些节点的传感节点按照策略休眠,对延长网络生存时间有重要意义,为了有效地进行节点的覆盖控制设计了节点自适应传感半径调整算法AASR(adaptive adjustment of sensing radius),使节点为自已选择合适的覆盖范围.从调整效果、能量消耗和覆盖冗余度几个方面对算法进行了模拟实验和分析,仿真结果表明,AASR能够有效提高节点生存时间,减少能量消耗,提高覆盖率. 在无线传感器网络中,在使用合适的覆盖控制算法、保证一定覆盖性的前提下,使一些节点的传感节点按照策略休眠,对延长网络生存时间有重要意义,为了有效地进行节点的覆盖控制设计了节点自适应传感半径调整算法AASR(adaptive adjustment of sensing radius),使节点为自已选择合适的覆盖范围.从调整效果、能量消耗和覆盖冗余度几个方面对算法进行了模拟实验和分析,仿真结果表明,AASR能够有效提高节点生存时间,减少能量消耗,提高覆盖率.
