Review of Potential Methods for Handover Decision in V2V VANET

Vehicular ad hoc network (VANET) enables the vehicles to communicate each other. This technology could lead the future of transportation system by enabling the safety application, traffic management, and passenger entertainment. However, due to the fast moving nodes and very dynamic environment, VANET has some challenges waiting to be solved. One of the problems is related with vehicle to vehicle (V2V) handover decision. In this paper, the problem related to V2V handover decision is investigated. Furthermore, several potential methods to solve the problem are presented. The implementations of those methods in VANET are surveyed to assess the potential. Finally, the advantages and disadvantages of each method related to the implementation for V2V handover decision are presented in discussion.
