设计了一种基于能量变化的无线传感器网络覆盖算法.通常网络节点连接的通信范围应该大于两倍的感应范围,但这将导致网络能耗的增加.提出的算法采用最少数量的节点来解决传感器网络的覆盖率和网络的连通性问题.测量结果表明,提出的覆盖算法可以满足传感器节点的通信范围小于两倍的感应范围.这将降低传感器网络的能量损耗.算法通过使用不同能量水平的活跃节点来降低能量损耗,并且可以延长系统的使用寿命.
A wireless sensor network coverage algorithm based on energy variation is designed.Generally, the communication range of network node connection should be more than twice the sensing range, but this will lead to the increase of network energy consumption.The proposed algorithm uses a minimum number of nodes to solve the sensor Network coverage and network connectivity.The measurement results show that the proposed algorithm can meet the sensing range of less than twice the communication range of the sensor nodes.This will reduce the energy loss of the sensor network.The algorithm through the use of different energy levels of active Node to reduce energy consumption, and can extend the life of the system.
