Research On Routing Optimization Algorithm For The Control Network Of Civil Aviation Aircraft

In the civil aviation industry,the Internet of things is used in the monitoring and control of airport equipment,in order to improve the stability of equipment operation,the punctuality rate of flight and the operational efficiency of the airport.The environment where airport equipment working is very complex,and because of weather and human factors,the flight schedule is random.So it is a challenge to collect and transmit data of equipment condition.Under the condition of limited energy storage and network load of wireless sensor nodes,in this paper,how to choose a reasonable routing mode and how to transmit the data to the host computer is studied.First,the monitoring network structure of the equipment based on IoT is proposed.Then,LEACH protocol is optimized by selecting the cluster head node to transmit cluster node data.In order to reduce redundant data and network overhead in the WSN,a data fusion method based on clustering is proposed.MATLAB simulation shows that the optimized algorithm can better improve the data communication and survival time of each node,and ensure the reliability of the monitoring system of the equipment.In order to solve the problem of data packet congestion and network delay in the monitoring system of civil aviation equipment,a CRAMP routing algorithm based on opportunistic forwarding was proposed.According to the characteristics of equipment working condition data classified by priority,in the process of controlling the number of message copies,transferring,caching and releasing,the data priority are taken into account.According to the priority and cache length of message packet,the cache and release order of the data are determined.Results show that the optimized algorithm can effectively reduce the number of message copies,and data redundancy caused by the routing overhead,ensure the load balance of airport ground equipment monitoring network.The routing algorithm of airport ground equipment monitoring network is optimized in this paper,then node energy efficiency and network performance are improved.It can transmit working condition data to the host computer,and provide reliable communication support for the whole working condition monitoring and control system.
