The vehicles are supposed to issue messages periodically to announce other vehicles about their situations such as speed, positioning and direction. Each vehicle equipped with communication devices will be a node in the Vehicular Ad hoc NETworks (VANETs) and allow to receive and send other messages through the wireless communication channels. This network will provide wide variety of services such as Intelligent Transportation System (ITS). The safety application is one of the most crucial application in ITS. For example, if a vehicle detects traffic jamming, it will inform other neighboring vehicles about this traffic situation.
