Connecting Pervasive Frameworks Through Mediation

Context information helps an application decide on what to do in order to adapt to its user’s needs. To easily develop ubiquitous applications, there has been increased research in the design and development of frameworks called pervasive computing frameworks. Although these frameworks help application developers create ubiquitous applications easily, interoperability has been a problem because of the different representation of context information and protocols used. This research attempts to solve this problem by creating a Context Information Mediator (CIM) which will serve as a translation gateway between different applications created using different frameworks. To test our system, we developed two versions of an inventory system application that keeps track of items inside a building. The idea here is to let these applications communicate with each other and share information through the CIM.
