Abstract

Ubiquitous services discovery without users requests (or guidance) is an important issue in ubiquitous environment. The ubiquitous systems mainly gathers the user and services context along with specific interests of users in selection right time the right services required by the user. Many of the existing service discovery schemes use a service matching process in order to offer services of interest to the users. In this work we propose a scheme to acquire the context information using CI-Constructs (Context Information Constructs) and analyze this information into observations from which beliefs are formed. The formed believes along with the users interest the system identify the user required service and guide the user to fetch the service. We propose a C-IOB (Context- Information, Observation and Belief) based service discovery model. With this formulated beliefs the required services will be provided to the users. The method has been tested with a typical ubiquitous museum guide application over different cases. The simulation results are time efficient and quite encouraging.
