Wireless sensor networks (WSNs) have many potential application areas including environmental monitoring, health, security and surveillance, and robotic exploration.The goal of WSNs is often to deliver the sensing data from all sensors to a Fusion Center (FC).The received signals at FC are estimated.One of the concerns in WSNs is the power constraint, because the sensors have only small-size batteries whose replacement can be costly.In this dissertation, we focus on distributed estimation and capacity analysis in WSNs with power constraint.In Chapter 1, we describe the background of WSNs consisting of source, sensors, and FC.We explain the fundamental theory related to the dissertation, i.e., mutual information and estimation theory.In Chapter 2, we present survey on distributed estimation and capacity analysis in WSNs.We discuss the distributed estimation problem based on several factors including bandwidth constraint, energy constraint, Multiple Access Channel (MAC) models, and the presence/absence of Channel State Information (CSI).We review the capacity analysis following
