In VANET single Network types i.e. WAVE is not sufficient to provide QoS. UMTS in integration with WAVE can provide efficient network connectivity – A Survey

Abstract

This survey provides an insight to the Qualtity of Service (QoS) provision in Vehicular Adhoc Networks (VANET) through Wireless Access in Vehicular Environment (WAVE) and Universal Mobile Telecommunication System (UMTS). In order to provide ubiquitous and pervasive connectivity for the high mobility vehicular networks in dynamically changing context and service adapting situations, careful techniques must be adopted to provide QoS in VANET applications. To address different implementation scenarios and overcome the shortcomings of WAVE and UMTS, I some alternatives were captured to improve QoS in VANET either by amalgamating WAVE/UMTS or through some other viable protocols
