The mission of the Vehicular Ad-hoc Network research group is to perform academic research in order to develop a stable routing protocol. This protocol would be applied in baharestan city.

One of the main problems in the VANET routing algorithms is related to the duration of established routes. In these networks, due to their frequent changes in the network topology, the link duration is often very short. Short link duration decreases the network efficiency. Because of high speed of nodes and fast topological changes in this network, the link breakage occurs very frequently in VANET. When vehicles move out of the transmission range of one another, the link breakage occurs. Each link breakage leads to three problems: 1) Lose of some data packets.  2) The necessity of establishing a new path; this process is subjected to delay. 3) The flooding required for new path finding. In the literature, the position, direction, speed, and speed vector of cares have been used to find the stable routes. In our research we want to applied other explicable phenomenon in order to develop more stable routing algorithm.
