Abstract
Vehicular Ad Hoc Network (VANET) has recently attracted considerable attention. The design of routing protocol for VANET is a challenge given rapid topology changes and frequent network disconnection. Current routing protocols usually use geographic information to forward packets. In this paper, we propose a traffic adaptive routing scheme called TAGR for inter-vehicle communication in urban scenarios. The key differences between TAGR and other geographic protocols are the process of real-time vehicle traffic estimation and Traffic adaptive selection of optimal route. Firstly, the position data that our location service provides is analyzed and aggregated to estimate vehicle densities of roads. Secondly, TAGR considers the movements of nodes (vehicles) and takes advantage of the predictable mobility pattern of vehicles. TAGR utilizes traffic information and movement predication to create adaptive connectivity model which improves the routing process by selecting the most stable route. Simulations in realistic city environments are conducted to compare the proposed protocol with GSR and GyTAR protocols. The results show that TAGR outperforms the others in terms of data delivery ratio and average delay
