Design of an Adaptive Sign Based Routing Protocol in VANET for Sophisticated Environments

With the advancement of the communication technology and an increase in the number of vehicles, the Vehicle Ad-hoc Network (VANET) has become an emerging field of study. The major applications of VANETs are in highways, but in sophisticated environments such as forest area, hill stations, private museum or large park etc., where visitors across the country pass through several locations, and there doesn’t exist a proper communication among the vehicles. So in this type of locations, we need an intelligent routing strategy for the On Board Unit(OBU) to adapt and communicate with the neighboring vehicles. In this paper, a strategy is proposed wherein, the vehicles communicate with each other or with the roadside units (RSU) by passing some sign bits with positive or negative polarity. A simple simulation is performed on 100 to 200 vehicles demonstrating passing of data from source to destination.
