Frame work for context aware applications

In fast growing world we are in need of information for place we are in right now. For these types of services the Pervasive Computing is used. In Olden days, if we need some information means, we have to go to our computer and had the necessary information. Nowadays we have our laptop Computer with us and have the information where ever we are now. The sub domain of Pervasive Computing is Context aware Computing. People are in need of the computing should response based on the current context. The context is based on location, identity, activity and time. For that, nowadays there are several context aware computing system developed. Context aware system can produce the output based on the situation where the system is currently present, that is it acts according to the context. When people want to develop a context aware system they can adopt their own framework for their systems. So far there is no common framework irrespective of their domain in which the context aware system is developed. For each and every context aware system there are separate frameworks are used by the developer. By using separate framework the time taken to build the framework is wasted and the cost is also wasted. We have developed a framework and tested our framework with two separate context aware applications.
