Research On Dynamic Adaptive Routing Method For Internet Of Vehicle

With the continuous improvement of communication and network technology and the increasing number of private car trips,the pursuit of travel safety has gradually become the people's choice.Vehicle self-organizing network with the network topology changes frequently and the poor stability of the communication link.Because of the above properties,it is more difficult to improve the routing algorithm to meet the high reliability and low latency.Therefore,the research of dynamic adaptive routing algorithm becomes more and more important.This paper studies the key technologies of routing in car networking,introduces the communication architecture and routing protocols in car networking,studies the factors influencing routing performance in car networking,and compares the routing design methods in car networking comprehensively.In order to solve the frequent changes of network topology in VANET,this paper proposes a new dynamic and adaptive routing method for internet of vehicle.The probability of connectivity as an important parameter of the dynamic adaptive routing method for high-speed-road scenario of the Internet of Vehicle,we propose a new method to calculate the probability of connectivity.The method is based on the distance(spacing)of the parameters node and its nearest node(the distribution of the spacing is exponentially distributed).The proposed routing method uses the Greedy Opportunity Forwarding(GOF)algorithm.The GOF algorithm effectively improves the performance of the car networking in terms of packet delivery rate and average number of hops,and improves the performance of the algorithm in the simulation environment.In order to solve the routing problem in VANET,this paper,we use the evolving graph theory to model the VANET communication graph on a highway.The extended evolving graph helps capture the evolving characteristics of the vehicular network topology and determines the reliable routes preemptively.A new link reliability model based on the mathematical distribution of vehicular movements and velocities on the highway is developed,and considered the link reliability measurement.A reliable routing protocol is designed to benefit from the advantages of the extended evolving graph model to find the most reliable route.This way,the routing overhead is significantly reduced,and the network resources are conserved.The Novel algorithm is improved in the simulation environment.
