LEGATE: Location management system for logical Group-bAsed Tracking of mobile nodes in retailing malls

Location is a kind of contextual information that is often realized through localization technologies in strict sense. The technologies such as WSNs provide geographical location as in Cartesian coordinates or in referenced landmarks, rendering a rigid and unilateral interface to multiple applications. A myriad of applications using localization technologies often do not require precise location, instead need to syntactically process location information with newer contexts. The current work in localization does not abridge location and context. In this paper, we have presented the idea of logical groups; a bridge between context and location. The idea is substantiated through LEGATE, a location management tool, whose design and operation is shown to be of relevance and practical significance in commercial applications.
