摘要: 针对采煤工作面无线监测网络能量分布不均、人工维护和更换节点电池难度大、部分监测节点能量受限等问题，利用采煤机周期性移动的特点，提出了一种基于移动节点的采煤工作面无线监测网络能量优化方法。通过在采煤机上安装移动节点，对网络中监测节点采集数据进行转发，从而减少数据多跳传输，并通过设置传输阈值减少冗余数据传输，以降低节点能耗；利用移动节点向监测节点辐射射频能量，对监测节点进行有针对性的能量补充，从而实现网络节点能量均衡。实验结果表明，与LEACH协议相比，该方法可使无线监测网络能量分布更加均衡，有效降低网络能耗和同一运行轮次下监测节点死亡率，使网络有效生命周期延长了2.8倍。Abstract: In coal mine working face, there are problems such as uneven energy distribution of wireless monitoring network, the difficulty of manual maintenance and node battery replacement and energy limitation of some monitoring nodes. In order to solve the above problems, an energy optimization method of wireless monitoring network in coal mine working face based on mobile nodes is proposed by using the characteristics of periodic movement of the shearer. This method installs mobile nodes on the shearer to forward data that collected by monitoring nodes in the network to reduce multi-hop data transmission, and reduces redundant data transmission by setting transmission thresholds to reduce node energy consumption. The mobile nodes are used to radiate radio frequency energy to the monitoring nodes, which provides targeted energy supplement to the monitoring nodes so as to achieve energy balance of the network nodes. The experimental results show that compared with LEACH protocol, this method can make the wireless monitoring network energy distribution more balanced, reduce the network energy consumption and monitoring node mortality rate effectively under the same operation round, and extend the effective life of the network by 2.8 times.
