摘　　要：近年来,机场噪声污染愈发严重.为了全面、可靠、准确的感知机场噪声,设计一种基于Zig Bee等物联网技术的机场噪声感知方案.并进一步提出了一种适用于机场噪声感知的改进Zig Bee路由算法:通过引入邻居表实时感知邻居节点状态,优化了路由混合选择策略,避免了不必要的路由分组;同时为了避免父节点失效影响子节点通信,通过减小侦听时间有效缩短了路由维护时间.仿真实验表明新算法较ZBR算法和AODVjr算法在报文投递率、路由开销百分比、端到端平均延迟和网络剩余能量百分比方面均有一定改善.In recent years ,the airport noise pollution is increasingly serious. In order to monitor the airport noise comprehensively relia- bly and accurately, this paper designed an airport noise monitoring scheme based on IOT technologies, and further proposed a Neigh- bor-table-based ZigBee Routing （NZBR） algorithm for airport noise monitoring. The algorithm optimized routing hybrid selection strategy by neighbor table;this algorithm can reduce redundancy of RREQ （ Route Request） packet and energy consumption of net- work. Besides, excessive energy consumption always causes nodes to be ineffective. NZBR algorithm uses neighbor-table to reduce link repair time. The simulation result demonstrates that NZBR algorithm performs better than ZigBee routing algorithm in packet delivery ratio, routing overhead ratio, end-to-end average delay and remaining energy ratio.
