Study Of Airport Noise Monitoring Platform And Networking Based On Internet Of Things

The rapid development of the civil aviation has been played a tremendous role in promotingeconomic and social development, but aircraft noise pollution has affected the sustainabledevelopment of civil aviation seriously. The application and development of the Internet of Things(IOT) provided the possibility for the fine-grained monitoring of airport noise. With thecomprehensive implementation of strategy of strengthening our civil aviation, it is very important tocarry out studies of the airport noise and related topics based on IOT. This paper mainly focused onthe airport noise monitoring platform and routing algorithm of sensing layer based on IOT.This paper analyzed the existing architecture of IOT, and designed a kind of four-tier architectureof IOT for airport noise monitoring system. This model contains Perceptional Layer, NetworkingAccess Layer, Data Fusion and Security Layer, and Application Layer. The airport noise monitoringplatform designed in this paper was a fundamental platform. ZigBee was selected as the solution toPerceptional Layer through analysing and studying the short-range wireless communication schemes.By the data characteristics of aircraft noise, a multi-path routing algorithm based on the tree-topology of ZigBee was put forward. By introducing the routing table of neighbor nodes and themechanism of Hello message, the improved algorithm can find one or more transmission paths whichcan reach the node of sink, which reduced the transmission delay effectively. By introducing themechanism of reliable communication, the algorithm can adjust the amount of data on each pathwhich improved the reliability of data transmission through considering information such as theresidual energy and depth of neighbor nodes. The results of simulation showed that the improvedrouting algorithm not only achieved the requirements of low delay and high reliability of nosiemonitoring platform, but also balanced the load of network and prolonged the survival time ofnetwork.In order to connect Perceptional Layer to the backstage server, this paper designed a new kind ofIOT Gateway, which was responsible for the processing and transmission of data. Through connectingto the Internet by a wired or mobile netwoks, the Gateway enabled data transmission between usersand Perceptional Layer.
