Research On Networking Technology Of Airport Noise Perception

In our country, with the rapid development of civil aviation, the growing air traffic makes the airport noise problem more serious. As the traditional airport noise perception can’t be deployed in large-scale, it’s possible to sense airport noise reliably, accurately and roundly with the development of Iot technology in recent years. The networking technology research of airport noise perception is not only of great significance to civil aviation, but also has a role in promoting development of the Iot. This article study networking technology of airport noise perception mainly from the three aspects below: networking scheme, network protocol and the realization of networking technology.In the networking schemes, we proposed a networking scheme based on IOT’s three layer architecture. The proposed scheme widely deploy sensor nodes in the airport and its surrounding areas as grid, the sensor nodes monitor noise and transmit data via Zig Bee, the aggregation nodes receive data from router and sensor nodes, and then upload noise data to the processing center through the mobile 3G network. And we designed a kind of master-slave node competition access network scheme.In the network protocol, we studied zigbee protocol in several aspects. We proposed a neighbor-table-based hybrid routing algorithm and a neighbor-table-based link repair algorithm. This new protocol can reduce redundancy of RREQ(Route Request) packet and energy consumption of network. Reduce link repair time. The simulation result demonstrates that new protocol performs better than Zig Bee protocol in packet delivery ratio, average end-to-end delay and remaining energy ratio.In the realization of networking technology, first we designed hardware and software of sensor node and aggregation node. As the existing sensor nodes layout methods can’t apply to the networking scheme we proposed. We proposed a grid-enabled airport noise sensor nodes layout scheme, and a comprehensive evaluation standard based on analytic hierarchy process. At last we proposed a layout method based on series of simulation.Finally we implement the networking technology of airport noise perception we proposed in Tianjin Binhai International Airport and evaluate the performance.
