Optimal distributed detection and estimation in static and mobile wireless sensor networks

To my parents iii ACKNOWLEDGEMENTS I would like to express my sincere gratitude to my advisor, Prof. Edward J. Coyle, for his invaluable advice and persistent support during my Ph.D. study. Without his guidance, I would not have been able to successfully complete my dissertation. Moreover, his guidance in both my research and life has pretty much reshaped my way of thinking and working in the past several years and certainly for the future. my defense committee. Their advice and comments have helped me to improve my dissertation. I want to thank the many other faculty, staff, and students at Georgia Tech who have given me a lot of inspiration and help during my study here, especially my lab mates: Ghaith M. Matalkah, Seskan Laitrakun and Ximeng Mao. I would also like to extend special thanks to Dr. Junlin Li, who was the earliest one to introduce to me the topic of distributed signal processing in wireless sensor networks and some interesting research by Prof. Coyle and his previous students. Finally I would like to express my deepest gratitude to my parents for their unconditional love and support. It is to them that I dedicate my dissertation. 1 Comparison of the energy allocation schemes under different crossover probabilities of the BSC channel. Bits are allocated first to the sensors closest to the CH, with sensors in the third ring contributing more bits as the channel crossover probability p c increases. Recall that p abc is the probability that node b in ring a transmits 2 2 Comparison of the energy allocation schemes under different crossover probabilities of the BSC channel.

As the measurement noise becomes more severe (as V increases), sensors in the outer rings must contribute – but the energy cost of transmitting over multiple hops ensures that the sensors in the inner rings use the most bits. p c = .05 and the MSE is held at 0.015. 1 A Cluster-Head (CH) of the eStadium sensor network in Ross Ade stadium at Purdue.
