Abstract
Vehicular ad hoc network (VANET) is a category of mobile ad hoc network (MANET). VANET provides wireless communication among vehicle-to-vehicle (V2V) and vehicle to a computing device located on roadside infrastructure called Road Side Unit (RSU). The communication between vehicles can be used for safety provisioning and emergency awareness by exchanging information among traffic participants to realize a cooperative and more efficient transportation system. An important issue associated with V2V communications used for traffic safety and emergency awareness applications (TSEAAs) is better routing with the Quality of Service (QoS) support. This paper reviews the existing QoS routing protocols based on the two important parameters: link efficiency and link stability.
