Information Exchange in Vehicles Ad-Hock Networks

For wireless vehicular communication both Europe and USA adopted IEEE802.11-2012 (WiFi) based communication systems. These systems are road infrastructure independent type of communication enabling both vehicle with vehicle communication as well as vehicles communication with infrastructure. However, as WiFi radio system architects stressed low system complexity, adopted communication system reaches the only sub-optimal performance with relatively low spectral efficiency, limited communication capacity and principally reduced services guaranteed performance as well as the only restricted possibility of farther system performance enhancement. New generation of 3GPP cellular networks with progressively growing services availability can in future offer alternative solution to WiFi based systems with much higher spectral efficiency and communication capacity and with possibility to guarantee communication services performance. Recently were introduced 3GPP proximity services and their extension devoted for vehicular communication. Such communication system augmentation opens possibility of full 3GPP communication systems engagement in the extensively growing vehicular communication. In this paper is discussed future expected development in this systemic area as well as both communication systems potential coopetition
