A review paper on context: Awareness system of mobile computing.

In various fields of computer science the word meaning has been explored. In various fields such as Smart Environment, Distributed Computing and Contextual Consciousness, context conscious devices are in popularity. Context Aware System is the new path towards the technology in Mobile Computing. This is a portable computing component where mobile apps can detect spatial data (e.g. User Place, Period of Day, nearby people, locations and user activities). Now in the era of Mobile Computing, recently we have seen the new developments in Apple iPhone-5 and Samsung Galaxy Note where they have application of Context aware System but it is not that what we call a "Killer App". Context conscious System is an old field but a rich field of research. In this paper, the difficulties and possible solutions are discussed which can serve as guidance to the developer or a researcher hoping to make an efficient Context Aware System a reality.
