Abstract
One of the important QOS parameter in highly dynamic VANETs is minimum delay. There has been a continuing innovation in the area of routing for the VANETs to find the optimal path between source and destination. Many protocols have been proposed and deployed to realize the benefits of intelligent transportation systems (ITS) in VANETS. But still the question arises is how best, the protocol finds optimal path besides the rapidly changing environment? However no single protocol excels for VANETs. Due to high mobility and lossy characteristics of wireless medium, it’s really a challenging question to find the optimal (shortest path) and at the same time, a lossless path which guarantees packet delivery. Guaranteeing packet delivery is the top most criteria in networks like VANETs. The importance of VANETS is better realized in the area of accident prevention and obviously, a safe driving. Link failures are frequent in VANETs and so the responses that arise from the protocol would degrade the performance, when the network size increases. So from our research study ,the issues that needs to be addressed for efficient routing are link failures , scalability, minimum delay and so a guaranteed transmission of real time data in accordance with the dynamic environments. In this paper, we propose a new algorithm to facilitate the reliable and efficient routing in VANET’s. The new algorithm enhances the well-known ad hoc on-demand distance vector (AODV) routing protocol to propose the location-based scalable routing protocol AODV-r. Simulation results demonstrate that AODV-r outperforms significantly the AODV routing protocol in terms of better delivery ratio and small end-to-end delay while maintaining a reasonable routing control overhead. We had also proposed a new metric called Extended ETX which enhances the original ETX.
