Wireless Transmission Impact on the Lifetime of Routing Path in VANET

In recent years there has been a growing interest in the field of vehicular networks, primarily due to the advancement in technology and need for safety and entertainment applications. The current generation of vehicles has embedded computers, GPS receivers, and number of sensors, where as the next generation of these vehicles will potentially have short-range wireless network interface. The target of ITS (Intelligent transport system) is to increase safety of passenger by exchanging warning messages between vehicles, this can be done by offering on-board network applications which is a challenge for the scientific community. In addition to safety applications, other telemetric services could improve traffic efficiency environment preservation, comfort and provide a reliable journey. Since VANET (Vehicular Adhoc Network) is composed of vehicles equipped with short range wireless communication capabilities. The performance of vehicles can be affected by high mobility pattern of the vehicle, speed of vehicle, transmission range, network breakup, traffic density and number of vehicles in the route. This paper describes the effect of the wireless transmission range on the lifetime improvement of the routing path in VANET, simulation result obtained helps to select the appropriate transmission range for increasing the lifetime of the routing path.
