Vehicle-network load balancing method in cooperative intelligent transport system

摘要

Next-generation intelligent transportation system that distributes the network load by defining the load between the vehicle and the network (mobile, infrastructure) using the SDN (Software Defined Network) concept, and defining each vehicle and mobile as a sub-node of the controller using the infrastructure as a controller. In the vehicle-network load balancing method, through the SDN (Software Defined Network) concept, in the state of determining each vehicle as a node with the controller as the infrastructure, through the vehicle-to-vehicle communication, the throughput between neighboring vehicles in each vehicle (throughput ) Obtaining information, transmitting header information from each vehicle to the controller, the infrastructure, determining a sub-node to communicate with itself for load balancing using the shortest time path calculation algorithm in the infrastructure, and determining the sub-node Through the step of transmitting the road information to all vehicles through, to implement a load balancing method between the vehicle and the network in the next-generation intelligent transportation system.
