Abstract: In order to meet the need of intelligent monitoring in grouting engineering,considered the effective coverage rate of wireless sensor networks ( WSNs) and the energy consumption of nodes,the layout method of wireless sensor nodes in complex corridors is studied. the cluster node strategy and layout method of the wireless sensor node in the corridor be analyzed through improvement the LEACH protocol. The factors influencing the cluster head election include the distance between the node and the neighbor node,the residual energy of the node and the distance from the node to the base station as the research object,studied the cluster head election strategy and puts forward the weight-based wireless sensor node layout method which improves the LEACH protocol. By calculating the proportion of each factor and optimizing the election formula,the most reasonable cluster head node is selected. Combined with field experiments,a comparative analysis for the performance of the remaining nodes, network energy consumption and data transmission capacity is carried out. Experiments show that under the construction condition of grouting corridor. The node layout method for wireless sensor networks based on weight and effective network coverage is suitable for grouting corridor communication.
