A context-aware framework for mobile computing environment

Abstract

Context awareness is a computer application that uses context, that is usually used when a person communicates or acts. Context aware computing, a computing paradigm related to context awareness, provides quality service by being aware of users and its neighboring contexts in mobile computing environment. A main research issue in context aware system is to collect and transmit appropriate context data among related nodes in time. In addition, it is very important to design a framework to clearly define functions and roles in the system to provide scalability, reliability, flexibility and reusability. In this paper, we design a logical integrated model for context aware system. We then propose a context aware framework for mobile computing environment based on environment monitoring using a sensor network. Comparison with other context managing framework architectures shows that our framework provides security and privacy lacking in other architectures.
