Abstract:
Ubiquitous computing aims to exchange and share services anywhere, anytime. However, discovering the appropriate service in ubiquitous environments poses very specific challenges. In this paper, we propose a new Semantic and Dynamic Cluster based Web Service Discovery System (SDC- WSDS) which deals with dynamicity and scalability challenges. Our discovery system is based on a clustered architecture and supports semantic publication and discovery queries. We, hence, present a new clustering algorithm for ubiquitous environments inspired by the Weighted Clustering Algorithm (WCA) and a semantic service publication and discovery model. This model is based on attribute value pairs and a semantic distance function.
