Based on the research on the characters of network in the pervasive computing environment, a rule-based method for network data collection and processing is brought forward. The method encapsulates the logic of network data collection and processing in business rules, and organizes the business rules through object-oriented Rete algorithm. Data processing logic is able to easily be read and verified. And business logic and process are separated by this method. At the same time, the complex business determinant statements do not have to be modified to adapt themselves to the changes of network environment and business.
