دانلود A novel multi-cast routing protocol for VANET

Abstract

Vehicular Ad-Hoc Networks is an ad hoc network connecting mobile vehicles which possess dynamic topology thus low link stability in terms of connectivity. The critical concern in ad hoc routing is routing which is handled via various routing solutions. This paper focuses on improving the I-AODV routing by considering V2V and V2I communication. The I-AODV (Infrastructure based AODV) is routing protocol that facilitate communication among vehicles through RSUs and is broadcasting in nature. This paper discusses prediction based multicasting which aids in reducing delay and improves other performance metrics. Broadcasting technique does not utilizes network resources which makes the network inefficient thus reduces throughput of the network , applying multicasting solves the purpose of proper utilization of resources as well as prediction technique helps in improving localization overhead. This technique improves the network performance metrics such as end-end delay, throughput, fuel emission, packet overhead and Packet Delivery Ratio.
