Semantic Service Discovery in a Middleware Based Ubiquitous Environment

A roaming user in ubiquitous environment should have access to different services anywhere anytime. In an infrastructure based smart environment, user acquires this facility from the middleware. Syntax based service discovery has proven to be inadequate for flexible interaction between user and the middleware; context based semantic matching is necessary. This paper shows the use of ontology to facilitate the semantic discovery of services in a ubiquitous middleware named Context Aware Middleware for Ubiquitous System (CAMUS).
