An efficient reactive location based ad hoc routing protocol for VANETs

VANET is an emerging technology to achieve intelligent inter-vehicle communications, consistent internet connectivity resulting in improved road safety, more important alerts and accessing comforts and entertainments. Within VANETs, Vehicle mobility leads to constant breakage of communication links between vehicles. Such link failures require a direct response from the routing protocols. This leads to increase the routing overhead and reduce network scalability. In this paper, we propose an efficient reactive location based ad hoc routing protocol. This protocol moves to reactive routing as location information degrades. Through analysis and simulation we show that our protocol is scalable in presence of high Location errors.
