چکیده
Further research has been done in order to reduce the energy consumption of the mine roadway wireless sensor nodes and prolong the lifetime of the network. On the basis of analysis and study on the existing linear wireless sensor network nodes deployment, the node distance optimization deployment scheme with sinks in the center is proposed. The calculation method for optimized distance between nodes is provided. The experimental simulation prove that, compared to the traditional deployment scheme, this scheme can effectively solve the problem of "energy hole", greatly reduce the energy consumption of single sensor node and whole system, and prolong the network life cycle. For mine roadway with long distance, the optimization deployment scheme with multisinks shall be used. According to number of optimized sinks, the monitoring area in the mine roadway is divided, the total energy consumption of system is minimized, the energy consumption of sensor nodes is balanced, and the network life cycle is significantly lengthened.

A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
