An assessment of various clustering techniques for VANET

Abstract

Vehicular Adhoc Network (VANET) is a technology where various vehicles on the road use Wireless Adhoc network technique for making communication among them for better driving environment and laser probability of roadside accidents. The vehicles are considered as wireless mobile nodes. These mobile nodes will form a network using various network topologies. These vehicles will communicate with each other using wireless communication technology. Intelligent Transportation System (ITS) is an application which plans to offer inventive types of assistance to traffic the board. The wireless nodes are allowed to communicate in about short range so vehicle networks are further divided in the clusters to make communication among neighbors’ vehicles within the cluster. The formation of clusters is based on various parameters like speed, direction, density, velocity etc. These clusters are variable in nature, so maintaining a cluster head in a cluster is a very tedious task. This paper surveys various clustering adopted in the VANET with their possible benefits and drawbacks.
