Particle Swarm Optimization based Routing Protocol for Vehicular Ad Hoc Network

Abstract- VANET is new technology for integrating ad hoc network, wireless LAN i.e. WLAN and cellular technology which is abbreviated as Vehicular Ad Hoc Network. The main aim of VANET is to achieve efficiency intelligent vehicle to vehicle communication, inter-vehicle communications and improve road traffic safety and efficiency. Depending on the type of information used for routing, they can be classified into two categories: topology based and position-based. To improve the data delivery performance in large scale network we propose the combination of SIFT and DREAM. We have also analyzed the Particle Swarm Optimization (PSO) technique on SIFT & DREAM protocol so as to improve the performance of routing protocols considering different parameters. PSO is a population based optimization technique use for finding optimum solution. PSO technique is originated from social behavior bird flocking. In PSO optimum solution is obtained from the behavior of bird. Since PSO uses for network centric localization purpose, this approach generates network navigational decisions by obviating centralized control thereby reducing both the congestion and dela
