An Enhancement of Greedy Perimeter Stateless Routing Protocol in VANET

The technological development in the world has increased rapidly and touched various areas, especially communication technology, which evolves with the evolution of wireless technology. This technology has invaded several areas, including the transport sector which has benefited from a new technology allowing the communication between vehicles through a specific network called Vehicular Ad-Hoc NETwork (VANET). Hence, the purpose of this network is to maintain road safety and traffic efficiency as well as ensure driving assistance and internet services to vehicles. This objective is ensured through many sensors and a system of geolocation that allows the measurement of speed and distance between vehicles and also microcontrollers or even microprocessors. As a matter of fact, they are capable of processing the information from the sensors and thus allowing the vehicle to react to unexpected events. Despite this development, routing in VANETs has left mysterious points for researchers because of the high mobility of vehicles, which causes frequent changes in the topology. In this paper, we propose an enhanced version of GPSR that minimized transfer delays and control messages. We compare our proposal version to traditional GPSR using the network simulator (NS2).
