摘要
针对煤矿采空区的长带状结构特点,以提高煤矿监控系统的安全性为目的,在深入分析LEACH协议应用在煤矿采空区不足的基础上,提出一种LEACH-GOAF协议,该协议引入簇首竞选权值和多跳路由机制,从而实现能耗的均衡,利用NS2仿真表明,LEACH-GOAF协议能平衡网络中的节点能耗,延长网络生存时间.
The existing LEACH algorithm have disadvantages of coal mine with long strip structure. This paper proposed a LEACH-GOAF protocol to improve the safety of coal mine monitoring system. The new protocol introducting a weight value in the process of candidate cluster head and use the multi-hop routing mechanism, so it can balancing energy consumption. Simulation results show that the routing protocol effectively balances the energy consumption among cluster heads and achieves an obvious im- provement on the network life time.
