VANET is a self configurable network which plays an important role in public safety communication and commercial application. It consists of highly dynamic which keeps on changing the position and speed leads to inaccuracy in predicting of driver's position and results in wrong packet forwarding decision in VANET. GPRS is very well known geography routing protocols. GPSR faces routing problem of greedy forwarding the packet in wrong direction, routing loop, and packet loss, which afterwards switches to perimeter forwarding, and forwarding the data using perimeter mode increases the delay to avoid they uses greedy mode.
