Research On The Application And Security Mechanism Of Vehicle Self-organizing Network In Intelligent Transportation

With the rapid development of China's social economy,the automobile industry has also been rapid development,the car in people's lives play an increasingly important role.But at the same time,with the small increase in the number of cars,traffic accidents,traffic congestion and other problems have emerged,to the social economy,people's lives and property has brought huge losses.In order to solve these problems,Intelligent Transport System(ITS)emerges as the times require,and is applied to all aspects of life.It has a multiplier effect for the safety management of road traffic.Based on the research status at home and abroad,this paper studies the application of vehicle-borne self-organizing network in intelligent transportation based on intelligent transportation system and Vehicular Ad Hoc Network(VANET).This paper analyzes the actual demand of the current traffic system and the function and characteristics of the vehicle self-organizing network technology,including the characteristics of vehicle self-organizing network: the regularity of the node movement,the external information of the GPS positioning and the directionality and orientation of the information;Disadvantages: limited network topology,network topology changes rapidly,easy to block communication channels,wireless channel instability and the network vulnerable to deception attacks.At the same time,it analyzes the three functions of vehicle self-organizing network: security management,traffic efficiency management,auxiliary entertainment consultation,and analyzes the feasibility,problems and challenges of applying it to modern intelligent transportation system.Finally,the paper focuses on the research of vehicle collision avoidance system in safety management.In this paper,a vehicle anti-collision algorithm based on PF voting mechanism is proposed.The algorithm makes up the deficiency of particle filter and improves the positioning accuracy.It has been proved to have certain application value.At the same time,aiming at communication problem in collision avoidance system,A collision prevention communication mechanism based on Zigbee wireless network is used to replace the vehicle communication with centralized information processing communication method,which avoids the network congestion and message delay caused by a large number of broadcast messages and improves the network performance.
