25.4 TRACKING IN WHSNs

25.4.1 Problem Statement

Previous work mainly aims at event detection and tracking in wireless homogeneous sensor networks, in which a considerable number of one type of sensors equipped with the same sensing units are deployed. In addition, the event formed by only one attribute is mainly concerned. Due to the limitation of sensing capability, the existing approaches are obviously unsuitable for the event, which is a compound of multiple attributes and any one of the attributes cannot be perceived by only one type of sensor. Without loss of generality, a network composed of various types of sensors is called the WHSN.
