Clustering in MANET and VANET: A survey

Vehicular Ad hoc Network (VANET) as a special class of Mobile Ad hoc Network (MANET) differs from the latter in a number of parameters. Clustering and Cluster Based Routing (CBR) protocols are the two important areas where a lot research work is in progress at present in both of these categories of networks, especially in VANET. The aim of this paper is to present a snapshot of clustering techniques and CBR protocols with a special focus on VANET since clusters ensure rapid and reliable data transmission.
