Abstract: Aiming at the problem that sensor nodes are active in LEACH clustering algorithm, while there is no clustering to balance the network energy consumption in sleep scheduling algorithm to make the network lifetime do not reach the best state, according to the spatial characteristics of underground coal mine roadway, we propose a hybrid algorithm of rectangular coverage clustering sleep scheduling for wireless sensor network. First of all, the algorithm divides the nodes deployment into two, and clusters the nodes of the first coverage, and makes the nodes of the second coverage sleep. When a node is "death" in the first coverage, we wake up its neighboring node in the second coverage. The experimental results show that the proposed hybrid algorithm effectively improves the network lifetime.
