Performance evaluation of IEEE 802.11 for vehicular communication

The advancement of technology has always been driven to comprehend the need for the various aspects of life like productivity, efficiency and safety. Intelligent transportation system (ITS) is introduced as a part of the global efforts and advanced application to fill the needs. It has been shown to be promising strategy as it could enhance the traffic efficiency and promote on-road traffic safety through the utilisation of both vehicle-to-roadside (V2R) and vehicle-to-vehicle (V2V) communications. This special kind of communication is known as Vehicular Ad Hoc Network (VANET) technology. Multihop ad hoc network paradigm is considered to be backbone for many VANET development. Besides, the researches on VANET are mostly inherited from the result of Mobile Ad Hoc Network (MANET) related to multihop ad hoc transmission and routing protocol which have been modified and adjusted to acclimate to the feature of vehicular field. Due to rapid growth of VANET, IEEE standard committee (IEEE 802) has develop a standard defining functions and operation for VANET. This paper aims to accurately simulate the behaviour of VANET simulation with the key parameters of the standard developed by IEEE 802 committee. The performance of this standard is evaluated in the network simulation environment in Matlab with realistic vehicular mobility model.
