URECA: Efficient Resource Location Middleware for Ubiquitous Environment

We describe an effective resource location framework forubiquitous computing environments populated by a diverse set ofnetworks, devices, services and computational entities. Ourframework provides context adaptation with the aid of a middlewareservice to improve the quality of resource location. A resourcelocation protocol suitable to each type of network locates resourceeffectively by means of dynamic reconfiguration to the currentcontext. Our framework is also refined by support forinteroperability between different types of resource locationprotocols occurring across a hybrid ubiquitous network. Thesecharacteristics also reduce the control overhead for resourcelocation, saving resource, decreasing latency and permitting aconsiderable degree of scalability.
