【摘要】 根据矿井无线传感器监测网络的特点,提出一种适合矿井安全监测的路由协议—基于虚拟栅格的簇头多跳路由协议CHM-VG(cluster heads multi-hops protocol based on virtual grid)。该协议根据矿井巷道长距离带状分布的特点,参考能量损耗模型构造虚拟栅格形成簇结构。依据簇内平均能量和其他节点传输距离两方面因素选取簇头节点,并采用簇间多跳方式实现数据传输。实验结果表明该协议平衡了整个网络的能量消耗,有效地利用了网络资源,延长了无线传感器网络的生命周期。更多还原

【Abstract】 The characteristics of wireless sensor monitoring networks for coal is analyzed mine and put forward a routing protocol for security monitoring on coal mine application——Cluster Heads Multi-hops Protocol Based on Virtual Grid. According to the characteristics of the mine roadway long banded distribution,the routing constructs virtual grid that forming cluster structure based on energy loss model. It selects cluster heads according to the average energy and transmission distance of other nodes in cluster. The protocol uses multiple hops to realize data transmission between clusters. The simulation results show that the protocol balances the network energy consumption and uses the network resources efficiently. Meanwhile,it can prolong the lifetime of network.更多还原
