This document proposes an architecture called Collaborative Business Items (CoBIs) that bridges the gap between virtual business logic and real-world sensor networks. CoBIs implements business logic as services that can be deployed to and executed on sensor networks. This allows business rules and processes to interact continuously with physical items and environments. Key aspects of the CoBIs architecture include using standard service interfaces, hiding network details, and providing lifecycle management of services on sensor networks. The architecture aims to integrate wireless sensor networks into enterprise systems like ERP applications.
