Energy efficient routing based on ordered topology of coal mine equipment

Abstract：In order to reliably monitor the running status of underground equipment and prolong the life cycle of wireless monitoring network,a novel routing protocol was applied to replace the AODV protocol of Zigbee.A Zigbee-based virtual address energy efficient clustering routing protocol（ZVAEECP） was presented,which simplifies the distribution monitor nodes into two layers chain topology in the underground wireless monitoring system of hydraulic support.The optimal number of clusters was searched using a Free-space radio signal transmission model which can minimize total consumed energy of the sensor network per round,and the cluster was divided by utilizing the orderly arrangement of equipment to lead into the virtual address.The results show that comparing with the AODV protocol of Zigbee,ZVAEECP protocol increases by 50% or more network life time,and the maximum packet loss rate is 0.87% which is 12% as AODV in the same case.ZVAEECP protocol has longer network life cycle and higher reliability than AODV,while routing table only maintains a small number of information.The protocol can be extended to the other equipment with similar topology and appropriately applied in underground equipment monitoring.
