LA-GPS : A location-aware geographical pervasive system

Abstract

The advancement of mobile information systems is going in parallel with Geographical Information Systems where they both meet in providing location-aware services. New systems are providing a new pervasive GIS dimension where access to geographical attributes is being possible "anytime, anyplace and anyhow". In this article, we propose a system that provides mobile users with a service that corresponds not only to their requests but also to their preferences, location and querying time. Finally, we project the query results to construct a GIS map layer that is added to original GIS area map in order to provide more indications to the path that the user should follow in order to reach the demanded service.

Contextualized User-Centric Multimedia Delivery System for Next Generation Networks

“…Despite the validity of such an approach, it does not define interfaces outside a closed environment and does not target other types of context, namely presence, weather, time, etc. The work done by Kukhun et al [8] presents a location-aware geographical pervasive system that provides mobile users with a service that corresponds not only to their requests but also to their preferences, location and querying time. Although this vision is going towards the authors' ideas, the work only establishes initial ground steps and does not specify any kind of architecture.…”

“…There, the user and service policies are cross checked to ensure the user is The first service to be executed is the subscription of the rich presence status of the selected users (7). Upon execution, the enabler sends the initial subscription status of the requested users to the application (8). Then the broker subscribes specific contexts of a particular user or a set of them on behalf of the CUMDA (9).…”

Integrating BLIP into Location-Aware System: A Service-Oriented Method

“…R. Tesoriero [2] proposes a location-aware system for museums to help the visitor to get information about the exhibits in the museum. Katsuhiro Takata [3] System) [4] and OYT System [5]. RFID is also seen in location-aware system, such as LACO [1] and the location-aware system for museums [2].…”
