A ZigBee routing algorithm adapted to underground coal mine

Abstract

For problem of inconvenient energy supplement of node in ZigBee wireless sensor network of underground coal mine, a ZigBee routing algorithm adapted to underground coal mine was proposed. In the algorithm, neighbor table is adopted to reduce data transmission hops among nodes, and residual energy of node in the network is sufficiently utilized by use of dynamic control of node residual energy threshold. The simulation results show that the algorithm reduces energy consumption of node in routing process and extends running time of the network.
