Chen Cha · Computer Knowledge and Technology · 2014
Aiming at the characteristics of complex environment and wiring difficult in mine, according to mine real environment and system requirements, a four-storey clustering type chain topology of wireless sensor networks in the mine is built. The topology formation processes of stationary node networks, mobile node networks and whole networks are researched. Specially,the topology of mobile node networks is built by combination weighted LEACH algorithm,and the experiment simulation shows that the algorithm can reduce energy consumption effectively, and prolong the lifecycle of whole network. Meanwhile,aiming at the mobility of mine worker, the join strategy and leave strategy of mobile node are put forward respectively. The system has the specialties of multi-level, good stability and strong extensibility, which provides a good foundation for further data transmission and fusion and personnel location of mine monitoring system.
