Handover Techniques Routing Protocols and mobility management schemas for Vehicular Ad-hoc Networks – A Review

Abstract

The design of robotic vehicles in VANETs is the main consideration for Intelligent Transportation System (ITS). The primary motive behind this system is to reduce the risk of accidents and provide non-hazardous transfer of data messages and other security countermeasures. Various characteristics of VANETs like rapid change in topology, delay in data exchange, and infrastructure assets make it different from Mobile Ad hoc Networks. Hence, the routing protocols used for MANETS cannot directly opt for VANETs. In this paper, the primary routing protocols used in VANETs that are necessary for handover are discussed. Moreover, moving towards the next generation of 5g services, the end-users will have an option to use extraordinary and multiple functions simultaneously. As VANETs are engaged with high dynamic topology and high mobility rate achieving these services are still challenging and are tedious to provide QoS parameters with a high level of safety. The major outlook considered in this paper is the handover process. Handover is a mobility management approach in dynamic VANETs, which is a trending domain for researchers and industrial mobility providers. Thus, this paper deals with various handover techniques, routing protocols to maintain connectivity in handover and mobility management schemas to promote successful handover.
