A Survey on Mobility Management Techiques in Vehicular Ad-hoc Network

It came to the light of the world that last few years have brought a boom in the wireless communication. Continuous progresses in this field have opened new research field in computer networking aimed at enhancing data network connectivity to environment where the wired networks are not that practical. Due to importance of related applications vehicular networks are attracting most of the researchers and its mobility management is a challenging task due to small coverage range of 802.11 Access Point (AP) and fast mobility of the vehicles. Still now these traditional mobility management techniques cannot meet the requirement of vehicular networks and performance degrades. This article presents a comprehensive survey on mobility management solutions in vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) communication protocols in vehicular ad hoc network (VANET). Analysis is done on the critical issues over which the future vehicular applications should be deployed. The existing mobility management schemes are also reviewed. At the last, several open issues in mobility management for vehicular networks are outlined.
