A Stable Routing Protocol for Vehicular Ad hoc Networks

Vehicular Ad hoc Network (VANET) is a special kind of Mobile Ad hoc Network. VANETs are becoming a technology for connecting vehicle to computer networks. VANETs consist of dynamic nodes in the form of fast moving vehicles whose movements are restricted to road layouts and static nodes in the form of Road Side Units (RSU). Frequent communication disconnections between vehicles are happening due to dynamic and rapidly changing topology. This makes routing the packets from source to destination vehicles in VANET is a challenging job. This paper proposes a Stable Routing Protocol (SRP) for Vehicular Ad hoc Network (VANET). This paper mainly focuses on finding a reliable route between source and destination vehicles in VANETs. A new unicast routing protocol is proposed to route the packets from source to destination vehicles in a reliable and stable path by introducing Reliability Index (RI) metric.
