Survey on Modelling Context-aware Systems

Abstract

ABSTRACT. Context-aware system (CAS) presents completely novel opportunities for users and application developers through gathering context data and adapting systems behavior based on current situation. Particularly in relation to various types of mobile devices, high value mechanisms are utilized to increase usability of it.The usage of CAS hasbeen increased nowadays. The main objective of the CAS is to provide intelligence that has ability to detect context on behalf of the user. Modelling context-aware system is still developing and till date onlya small number of researches triedto present modellingofCAS. This reviewfocuses on the context aware system and conceptual design framework with respect to their principles and merits. This explains the two types of modelling CAS; the first one, when the context is certain and the second, when the context is uncertain.Each type has its own techniques. It is believed that this survey will make it easy for the software engineers to select the appropriate technique for the system.
