Abstract
Vehicle Ad Hoc Network (VANET) has been recently attracting an increasing attention from both research and industry communities. The specific characteristics of VANET pose difficulties and challenges on network control techniques, particularly, the mobility management techniques of vehicles, which are essential in providing seamless communication and guaranteeing user QoS requirements. In this paper, an overview of mobility management techniques in VANET is presented. The mobility scenario and the technical challenges in mobility management in VANET are discussed. Recent studies on performance enhancement of mobility management protocols in VANET is summarized and the problem of optimal mobile gateway selection is discussed. Finally, the related open research issues are discussed.
