Abstract

For the past few decades, there is a lot of advancement especially in communication technologies which provide an implementation of various networks in different environments. Vehicular Ad-hoc Network (VANET) is one of the end products of that evolution leading to have a greater scope in the near future. There is a lot of research that is going on VANETS in countries like US, Japan, and European Nations. The main reason for this is due to the standardization of VANETS in combination with infrastructure based communication contributes a new era in Intelligent Transportation Systems (ITS). This ITS enabled vehicles can be used for high level of transportation from conventional controlled car to an autonomous vehicle. ITS deals with road safety, faster transport, Collision avoidance and many other transportation problems that are faced in real time scenarios. A lot of researches have focused on VANET algorithms, routing protocols, broadcasting techniques and security related issues. Broadcasting in VANETS is highly unreliable due to the Broadcast storm problem. This can be minimized with the help of modified broadcasting technique by splitting the region based on density and followed by clustering mechanism. Such type of context aware mechanisms leads to increase in efficiency and Quality of service (QoS) of the system.
