Performance Analysis of Bio inspired Particle Swarm Optimization based Routing Protocols using QoS Parameters
VANET is new technology for integrating ad hoc network WLAN and cellular technology which is abbreviated as Vehicular Ad Hoc Network. The concept of VANET is to achieve efficiency intelligent vehicle to vehicle communication, inter-vehicle communication and improve road traffic safety and efficiency. Routing protocols are classified as topology based and position based routing protocol depending on type of information used for routing. 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 generate network navigational decisions by centralized control obviating thereby reducing the congestion and delay.
