We propose an approach to efficient communication which helpful to reduce traffic, accidents, jam, pollution etc. During the routing process it is to divide the vehicular network into clusters. In clustering Cluster Head (CH) & Gateway (GW) node those are responsible for communication with Junction. CH communicates information to GW or another cluster’s CH or GW. In this paper we are designed clustering model for efficient communication in VANET. Keywords: Clustering, Junction, City map, Cluster head, Gateway etc. 1. INTRODUCTION In wireless network number of vehicles is communicate to other vehicle this special type of wireless networks, known as vehicular ad hoc networks or VANETs [1]. To develop the safety of drivers and provide the comfortable for driving, messages for different reasons require to be sent to vehicles through the inter-vehicle communications and also using fixed infrastructure a new concept junction, those are fixed on road side helpful to maintain the record of traffic and send or forward valuable information to the passing vehicles. Improvement in wireless technologies [5] has help integrate the capability of wireless networks to vehicles [2] enabling them to communicate without any infrastructure; thus reducing deployment cost. IEEE 802 committee [3] defined standard, IEEE 802.11p [4], for the Wireless Access in Vehicular Environments (WAVE). The Federal Communications Commission (FCC) has allocated 75MHz of bandwidth for short range communications between Vehicle-to-Vehicle communication (V2V) and Vehicle-to-Infrastructure communication (V2I) which operates on 5.9 GHz. Multiple wireless technologies exist such as IEEE 802.11 (Wi-Fi), Bluetooth, WiMax, Satellite Digital Audio Radio Systems (SDARS) and but VANETs use Dedicated Short Range Communication (DSRC) [7] due to its low latency and ability to broadcast messages in multiple directions [5]. The range of DSRC is 1000 meters which is suitable for both V2V and V2I.
