前言/序言
Advances in micro electromechanical systems and wireless technologies have allowed for the emergence ofinexpensive micro-sensors with embedded processing and communication capabilities. A wireless sensor network (WSN) is a collection of these physically distributed micro-sensors communicating with one another over wireless links. In their various shapes and forms, the WSNs have greatly facilitated and enhanced the automated, remote, and intelligent monitoring of a large variety of physical systems and have found applications in various areas, such as industrial and building automation; environmental, traffic, wildlife, and health monitoring;and military surveillance. The purpose of a WSN is to provide users access to the information of interest from data gathered by spatially distributed sensors.In most applications, users are interested in a processed data that carries useful information of a physical plant rather than a measured data contaminated by noises.Therefore, it is not surprising that signal estimation, especially the multisensory fusion estimation, has been one of the most fundamental collaborative information processing problems in WSNs. The WSN, as a typical multisensor system, has greatly extended application areas of multisensor information fusion estimation,which was originally developed for military applications, such as target tracking and navigation. Although WSNs present attractive features, challenges associated with communication constraints, such as the scarcity of bandwidth and energy, as well as the delays and packet losses, in wireless communications have to be addressed in the WSN-based information fusion estimation and have attracted increasing research interest during the past decade.
