Vehicle-to-vehicle broadcast for highway safety applications

Vehicle-to-vehicle (V2V) communication is a potential method to improve road safety and reduce car accidents. In V2V communication, vehicles broadcast safety messages to inform drivers about the danger ahead. Safety applications based on the dedicated short-range communication in vehicular networks have very strict requirements of reliability and delay for safety messages. Meeting the reliability requirement is challenging due to the effect of packet collisions caused by hidden terminals and direct collisions. In this thesis, we analyse, design, and develop different techniques to improve the reliability of vehicular safety applications.
