Clustering and routing in mobile ad hoc networks (MANETs)

Abstract

First of all, I would like to express my sincere thanks and great gratitude to my supervisor, Assistant Professor Chong Han Joo Peter. Without his intellectual guidance, constant attention and strict demands, this work would have not been completed. His extensive knowledge, enlightened direction and continuous encouragement make my Thesis work much easier. In particular, I wish to thank him for teaching me some of the philosophical aspects of research and some intangible skills, which I believe are the most invaluable knowledge that I have acquired as a PhD student. I would like to thank the centre director, Associate Professor Shum Ping, technicians and many labmates, especially Dr. Li Xuejun and Dr. Yang Ming, in Network Technology Research Centre for their guidance, support and help in the past few years. I would like to express my gratitude to my family, especially my husband and parents, for their consistent support and encouragement during my PhD study and my life. Last, but not the least, I would like to thank Nanyang Technological University for providing all the study facilities and research scholarship. III

Safety of Mobile Wireless Sensor Networks Based on Clustering Algorithm

“…The proposed centrality metric considers residual energy of individual nodes, link quality, hop distance between the prospective cluster head, and respective member nodes to ensure better cluster head selection and cluster quality, which results in better scalability, balancing of energy consumption of nodes, and longer network lifetime. (Yu, 2012) try to secure clustering mechanism against wormhole attack in ad-hoc networks (communication between CHs) but after forming clusters, not during the election procedure of CHs. (Liu, 2012) surveyed the clustering algorithms available for WSNs but from the perspective of data routing.…”
