A Developing Approach of Information Acquisition System in Pervasive Computing Environment

How to effectively acquire information that users need is especially important in pervasive computing environment of wireless sensor networks. In this paper we present a kind of business rules about business activity-business object constraints, discuss the meaning of this type of complex business rules and study the relations among business activity, business object and business constraint. Based on this, a formalization of this type rule is presented. We also propose a methodology of this type business rule to implement information acquisition system. Through an example, it is proved that this methodology improves the adaptation to dynamic pervasive computing environment of wireless sensor networks
