Programming Secure and Robust Pervasive Computing Applications

We have developed a programming framework for building context-aware multi-user collaborative applications in pervasive computing environments. It supports context-sensitive security and multi-user coordination requirements. It also supports error handling in pervasive computing applications through an exception handling model. In this paper we present the programming framework and demonstrate its utility for building context-aware, secure, fault-tolerant pervasive computing applications. We also demonstrate integration of an agent-based distributed event monitoring system for gathering context information that is derived from sensor data.
