详细研究了现有的LEACH路由协议,为了解决LEACH路由协议由于簇头节点死亡而造成无线传感器网络(WSN)生命周期短的问题,结合矿井瓦斯检测系统的特点,提出了一种基于地理位置分区和节点剩余能量的改进的LEACH路由协议。这种改进的路由协议在簇首选择机制上相对于现有的LEACH路由协议做了一定的改进,通过综合考虑传感器节点位置、节点剩余能量参数,有效避免了低能量节点被选为簇首。结果表明,该路由协议能有效地平衡簇首的能量消耗,提高矿井中瓦斯检测系统的网络生命周期。
In order to solve the problem of short life span of wireless sensor network (WSN) due to the death of cluster head node in the LEACH routing protocol, the existing LEACH routing protocol is studied in detail. Combining with the characteristics of mine gas detection system, a new routing protocol based on geographic location And improved LEACH routing protocol for node residual energy. Compared with the existing LEACH routing protocol, this improved routing protocol improves the cluster head selection mechanism. By considering the location of sensor nodes and the remaining energy parameters of the nodes, the low energy nodes are effectively avoided from being selected as cluster heads. The results show that the routing protocol can effectively balance the energy consumption of cluster heads and improve the network life cycle of gas detection system in mine.
