摘要
针对三维空间下的无线传感器网络覆盖问题,考虑在满足最优覆盖节点集的基础上,同时减少网络能耗,提出了一种半径可调的三维无线传感器网络的低能耗覆盖方法.根据节点具有可调节传感半径的属性,在三维空间中利用遗传算法动态优化节点布局.仿真结果表明,节点的部署能够在达到较高的覆盖率和节点休眠率的同时,有效降低网络能耗,从而延长网络的生存时间.
Coverage problem for wireless sensor networks in three--dimensional space, In order to achieve the optimal coverage node set, taking into consideration the characteristics of the network energy consumption, this paper present a energy efficient coverage control for 3D wireless sensor networks based on the adjustment of sensing radius. Rational combination of nodes by the genetic algorithm based on the adjustment of sensing radius attributes of sensors in three- dimensional space. Simulation results show that the nodes deployed can improve rate of coverage and sleeping node, and reduce network energy consumption, Therefore, the survival time of the network will be prolonged.
