摘　　要：我国民航业发展造成了严重的机场噪声污染,针对机场噪声监测网络中节点能耗高而过早死亡、网络易发生拥塞和延迟等问题,提出基于物联网的噪声监测网络方案和基于分层协作的中继路由算法NCRA。结合机场运行标准和监控网络的特点,提出节点能量均方差和网络负载平衡因子,综合权衡节点到基站的距离关系,选择合理的中继节点分层转发噪声数据;根据节点的能耗速度和剩余能量确定簇头节点,保证簇内网络的能耗均衡。通过算法分析和仿真验证,NCRA能更好地平衡网路负载,提升数据传输量和网络寿命,保证机场噪声监测网络数据传输的可靠性和稳定性。The development of China civil aviation industry has caused serious noise pollution. Aimed at the problems of high energy consumption, data congestion and network delay in the airport noise monitoring network, a noise monitoring network scheme based on Internet of things and a relay routing algorithm based on hierarchical cooperation(NCRA) are proposed. According to the characteristics of airport operation standards and monitoring network, the concept of node energy average variance and network load balance parameters were proposed and calculated to select the reasonable relay nodes to forward the noise data. In order to ensure the energy balance of cluster network, the cluster head node was determined according to the energy consumption rate and the residual energy of the nodes. The algorithm analysis and simulation results show that, NCRA can balance the network load better than other protocols, improve the data transmission and network lifetime, and ensure the reliability and stability of data transmission in the airport noise monitoring network.
