The purpose of this paper is to aim to develop a new way to model mobile entities and manage their contexts accordingly.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Design\/methodology\/approach<\/jats:title><jats:p>This paper proposes the concept of \u201cMobile Space\u201d to model mobile entities and presents strategies to manage the various contexts associated therein. To handle availability related issues, two system services are designed: the \u201cAvailability Updating Service\u201d which is an identifier based mechanism and is designed to keep track of mobile objects and handle availability related issues, and the \u201cApplication Callback Service\u201d which is a publish\/subscribe based mechanism to handle application disruptions and interruptions arising due to mobility.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>The paper presents a detailed study of the proposed framework and a description of the underlying services and the components therein to validate the framework. Experimental results carried out in WiFi and 3G environments indicate that the proposed techniques can support mobile applications and minimize application disruptions with minimal overhead.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>The proposed context management framework is generic in nature and is not designed for a specific class of applications. Any mobile context aware application can leverage on the framework and utilize the provided functionalities to manage application disruptions. Also, the decoupling of mobile application layer and the underlying context data management layer renders context data management layer transparent to the application design.<\/jats:p><\/jats:sec>","DOI":"10.1108\/17427371211245382","type":"journal-article","created":{"date-parts":[[2012,6,23]],"date-time":"2012-06-23T07:14:24Z","timestamp":1340435664000},"page":"185-210","source":"Crossref","is-referenced-by-count":4,"title":["A context management framework for context\u2010aware applications in mobile spaces"],"prefix":"10.1108","volume":"8","author":[{"given":"Penghe","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shubhabrata","family":"Sen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hung","family":"Keng Pung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenwei","family":"Xue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wai","family":"Choong Wong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"doi-asserted-by":"crossref","unstructured":"Athanasopoulos, D., Zarras, A.V., Issarny, V., Pitoura, E. and Vassiliadis, P.
