Mobility Management in Vehicular Adhoc Networks: A Review

Vehicular Adhoc Networks (VANET) are gaining importance in vehicular networks and attracting an increasing attraction from both industry and research communities. Mobility Management is one of the most important and challenging research issue in vehicular networks which support various applications of Intelligent Transportation System (ITS). A specific mobility management solution is required for Vehicular Adhoc networks, because traditional mobility management schemes for mobile Adhoc networks (MANET) cannot meet the requirements of vehicular Adhoc networks (VANET) due to its unique characteristic (i.e. high mobility). In this paper, an overview of mobility management techniques in VANET is reviewed in three vehicular communication modes, i.e., Vehicle to Infrastructure (V2I) communication, Vehicle to Vehicle (V2V) communication and Hybrid Vehicle (HV) communication. Finally, the related open research issues are discussed.
