Abstract

Vehicular Ad Hoc Networks (VANETs) have received large attention in recent times. There are many applications bringing out the new research challenges in the VANET environment such as vehicle to vehicle communication, road-side vehicle networking etc. Road-side data access in the two intersecting roads of downtown area in VANET is the main consideration of this paper. Caching is a common technique for saving network traffic and enhance response time, especially in wireless environments where bandwidth is often a scare resource. In this paper, a novel Road-Side Information Station (RIS) data distribution model with cache scheme in VANET for the data access in the two intersecting roads of downtown area is proposed. The performance of the proposed scheme is tested through simulations. The simulation results reveal that the proposed scheme can significantly improve the response time, and the network performance.
