A Hierarchical Routing Protocol Based on Energy Efficiency and Chain Structure for One-Way Aerial Ropeways for Underground Mine

In order to reliably monitor the operating status of one-way aerial ropeways for underground mine and better guarantee the safety of mine personnel, a hierarchical routing protocol based on energy efficiency and chain-type structure is proposed in this paper. Previous studies show that uniform cluster formation can prolong the lifetime of network. So a novel time allocation algorithm based on the residual energy of node is put forward to ensure that the starting time uniformly distributes in duration time of establishing network, when the nodes compete to become the cluster head node. Total energy consumption model based on free-space radio signal transmission model is used to search the optimal radius of node which can minimize total consumed energy of the network per round. The simulation results show that the proposed routing protocol is suitable for the operating status monitoring of one-way aerial ropeways for underground mine and the performance is better than LEACH.
