| 摘 要： | 寻找有效的节能方案以提高网络寿命是无线传感器网络中的核心问题。传统的最大化网络寿命致力于对节点进行休眠或激活的调度,在DLM算法的基础上提出一种ASR-DLM算法。其基本思想是对传感器节点的感知半径进行调整,提高能量的利用率,同时ASR-DLM算法改进了DLM算法中一旦探测到覆盖空洞即终止的缺陷,即在探测到覆盖空洞时,对覆盖空洞进行填补,ASR-DLM算法不仅能够保证完全覆盖,还可以在异构网络中进行,大大延长了网络寿命,同时不需要地理位置信息,扩展性很好。

| Abstract: | It is a core problem to prolong network lifetime using a mechanism that can efficiently utilize energy.Most existing works concentrate on designing a schedule,that is,a sequence of sensor covers to activate in every time slot,so as to maximize the lifetime of the network.We proposed ASR-DLM(Adjustable Sensing Range-Distributed Lifetime Maximization) Algorithm based on DLM(Distributed Lifetime Maximization) Algorithm.The basic ideas of ASR-DLM Algorithm is by means of adjusting sensing range.We can improve e... |
