An agent-based context-aware system on handheld computers

Context-aware system must adapt to changing contexts in dynamic environments, and it consists of a number of related subsystems, and each subsystem works together to achieve the functionalities of its parent systems. So, it is necessary to modularize the subsystems and it must be scalable and flexible infrastructure for the delivery, management and deployment of application to individuals. An agent-based approach through the OSGi service platform for context-aware systems leads to the development of more powerful abstraction mechanisms. This paper describes the overall architecture of an agent-based context-aware system, and that system can generate and provide high-level contexts to the applications and services. For the service interoperability, we use OSGi-based service platform. Using these agent modules and OSGi service platform that can act autonomously and interact in flexible ways, so we can utilize the context-awareness and modularization of complex context-aware system.
