摘要
提出了一种改进型LEACH算法。将能量因素加入到阈值计算公式中,均衡了节点的能耗。同时,针对重要参数难以通过实验的方式进行评估的问题,基于改进型LEACH算法建立了无线传感器煤矿安全监控网络的仿真模型,利用NS2仿真平台对其重要参数进行了仿真分析。分析结果表明,改进型LEACH算法能均衡节点的能量消耗,有效延长网络的运行时间,并且,通过仿真实现了系统模型参数的优化,验证了安全监控网络实施的可行性。
The paper proposed an improved LEACH algorithm that solved the problem about network operation for too short a time by traditional LEACH algorithm. The energy factor added to the threshold calculation formula, the balance of nodes＂ energy consumption. At the same time, sloved the problem about important parameters were too difficult to assess through experimental approach, the wireless sensor of coal mine safety monitoring network simulation model was built up based on improved LEACH algorithm, the important parameters were simulated in NS2. The simulation reasuhs showed that improved LEACH algorithm could balance the nodes of cluster and energy consumption and prolong the life time of network. And some simulating experiments were designed to optimize the system model parameters, verified the feasibility of the implementation of the safety monitoring network.
