In this paper we have understood, what are the basics of the 802.11 protocol, what is a wireless ad-hoc sensor network , what is a Mobile Ad-hoc Network (MANET), and details of Clustering . We have further understood what is clustering, why it is necessary, and the different clustering schemes. Among these we have understood their clustering process, the cluster maintenance, benefits and drawbacks , and finally compared them with each other . In our thesis we work with four clustering scheme and try to find out their formation and cluster head selection process time. We have understood these various concepts by extensive study of IEEE papers and acquiring information from the internet. We hope that our report will aid anyone seeking to understand information on this topic and be a concise compilation of information for their research or study.43 pagesenBRAC University thesis are protected by copyright.
