Reliable multi-hop forwarding in vehicular networks is required by many critical Intelligent Transportation System (ITS) safety applications. Cooperative vehicular multi-hop schemes achieve reliability using broadcast transmissions and multiple forwarding relays at each hop. However, packet duplication must be controlled to circumvent the broadcast storm problem. This paper proposes the Cooperative...
Multiple channels have been allocated in the 5 GHz spectrum for vehicular communications in USA and in Europe. Due to the limited spectrum, simultaneous communications may occur over nearby channels and be affected by adjacent channel interference (ACI). To protect safety messages delivered on the control channel (CCH), the most likely approach is to prevent the use of adjacent channels with the consequence...
With the increasing demand for traffic safety and efficiency and constant search for innovative solutions within the automotive market coupled with supporting initiatives from regulatory domains, the potential of Intelligent Transportation Systems (ITS) is immense. Basic vehicle and roadside infrastructure collaboration allows an increase in efficiency and safety and acts as the foundation for an...
