针对LEACH分簇算法中传感器节点都处于活跃状态,而在休眠调度算法中又没有对网络进行分簇来均衡网络能耗,使网络的生存周期未达到最佳状态这一问题;根据煤矿井下巷道的空间特性,提出了一种基于k重矩形覆盖的无线传感器网络分簇-休眠调度混合算法。该算法首先将部署的节点分成2重,对第1重覆盖的节点进行分簇,并且休眠第2重节点,当部署的第1重节点中的某个节点“死亡”时,唤醒第2重节点中与其临近的节点。实验结果表明,该混合算法有效延长了网络的生存周期。
LEACH clustering algorithm for sensor nodes are in an active state, and in the sleep scheduling algorithm and no network clustering to balance the network energy consumption, the network life cycle does not reach the optimal state of the problem; according to the underground tunnel , A clustering-dormancy scheduling hybrid algorithm for wireless sensor networks based on k-fold rectangle coverage is proposed. The algorithm first divides the deployed nodes into two groups, and clusters the nodes of the first repeated overwrite and sleeps the second heavy node. When a node “dying” in the deployed first heavy node is woken up, 2 nodes in the node near to it. Experimental results show that the hybrid algorithm can effectively extend the network life cycle.
