矿井无线传感器网络LEACH协议的改进

Improvement on LEACH Agreement of Mine Wireless Sensor Network

将无线传感器网络应用于煤矿井下通信,能够提高通信的安全性。无线传感器网络由能量受限的节点组成,通过部署这些节点以便收集特定监测区域内的有用信息。基于层次的LEACH协议通过将节点分簇以实现数据融合。针对矿井通信的特点对现有的LEACH协议进行改进,优化了簇头选择算法,允许节点采用多跳方式与汇聚节点通信,使其更符合煤矿井下的要求。经过NS2仿真平台的测试,改进后的LEACH协议使得整个网络在较低的能耗水平下获得了较长的生命周期,具有较好的能量优化特性。

The application of the wireless sensor network to mine communication could improve the safety of the communication. The wireless sensor network was consisted with the energy limited points. With the arrangement of the points, the available information within the special monitoring and measured zone could be collected. Base on the gradation LEACH agreement, the point bunch could have the data integration. According to the mine communication features, the present LEACH agreement was improved. The bunch head selection calculation was optimized. The points were allowed to have the muhi skipping mode and gathered point communication in order to fully meet the mine underground requirements. After the NS2 simulation platform tested, the LEACH agreement improved could let the full network have a longer service period under the low energy consumption and have good energy optimized features.
