一种应用于机场廊桥监控网络的路由算法

针对民航机场廊桥监控网络在机场停机坪现场测试中暴露的网络节点过早死亡、网络生命周期短的问题,对该系统无线网络架构中路由层算法进行优化,采用基于剩余能量和位置的改进LEACH算法,根据网络环境的因素综合考虑节点剩余能量、网络平均剩余能量以及节点位置,分步选出最优簇头,同时,采用能量估算方法确定网络平均剩余能量,达到均衡网络能耗且延长网络生命周期的目的.最终利用Matlab软件对民航机场廊桥监控管理系统建模仿真,仿真结果表明：提出的算法比网络原有路由层LEACH算法在均衡网络能耗和提高网络生命周期上均具有优越性.

A routing algorithm for airport lounge monitoring network

Aimed at issues of network note premature death and short network life cycle exposed in civil aviation airport lounge bridge monitoring network for field testing at the airport an improved LEACH algorithm based on remaining energy and location is presented, consider nodes remaining energy average remaining energy of network and node location according to network environment factor, select the optimal cluster head in two steps, at the same time, use energy consumption estimation method to determine average remaining energy of network to balance network energy consumption can prolong lifetime of WSNs. Modeling and simulation on civil aviation airport lounge bridge monitoring management system by Matlab, results show that improved LEACH algorithm performs better than original routing layer LEACH algorithm in balance network energy consumption, prolong lifetime of WSNs.
