A Chaotic-Based Routing Optimization Approach for Vehicle Oriented Service in VANET

With the development of the vehicular network, BusNet based service is of great interest to both bus companies and public users. But in this mode, due to the dynamic characteristics of the vehicle, how to effectively communicate has become a problem. In addition, considering the problem of jumping out of the local optimum, a new route optimization algorithm CSPSO (chaotic serial particle swarm optimization), is proposed. The comprehensive simulation results demonstrate that the proposed method can not only adapt to the dynamic changes of network topology, but also greatly reduce the possibility of falling into local optimum, and improve the communication performance significantly.
