Abstract

VANETS is associate degree rising new technology developed by group action accidental network, wireless LAN (WLAN) and cellular technology to modify intelligent inter-vehicle communications and to enhance road traffic safety and potency. VANETS square measure distinguished from other forms of accidental networks by their hybrid network architectures, node movement characteristics and new application eventualities. Therefore, VANETS cause several distinctive networking analysis challenges in specific areas as well as Quality of Services (QoS), economical channel utilization, measurability, quality and security and therefore the style of a QoS aware routing protocol for VANETS is extremely crucial. Analysis work is said to explore the assorted challenges associated with communication over VANETS by considering the QoS constraints. Provision of QoS constraints square measure vital factors that may have an effect on the performance of the routing protocol. Thanks to the various problems like variation within the node density, spare flow of management data, mobile atmosphere will degrade the performance of entire network thanks to the additional management overhead. During this survey paper, QoS problems and recently developed solutions are going to be mentioned which might improve the network performance.
