Enabling Technologies for Location Based Services (LBS)
 

Description: "Access of the right information anytime anywhere" is becoming the new driving force that drives the information technology revolution. The "right" information is information that is relevant based on the user's profile and his/her current position and/or time. Such services will contribute in improving individual and public safety (report the position of a casualty or of a fire). They will also facilitate effective information dissemination and enable individual or asset tracking. The benefits of such services will be immediately obvious to a number of industries as well as visible to many individuals. This project aims at developing the technologies that will allow wide deployment of such services. Specifically, during this project we investigated various Automatic Location Identification (ALI) techniques . We analyzed the Received Signal Level (RSL) approach and derived location estimates through Maximum Likelihood Estimation (MLE). The simulation results we obtained so far are promising and indicate that they can provide location estimates that are more accurate than similar techniques.

This project involves collaboration between the University of Cyprus and the Cyprus Telecommunication Authority (CYTA) and consists of two main parts. The first part is concerned with the investigation of technologies that improve the accuracy of automatic location identification estimates. We shall investigate the existing methods and will seek to improve their accuracy using intelligent systems as well as derive new approaches based on stochastic modeling and analysis. The second part involves the development and deployment of pilot location based services (LBS) which will allow service providers to disseminate information based on the subscriber's location. A number of LBS will be developed including a service for identifying the exact location of an emergency call such that emergency crews can act immediately, thus improving their chances for success. It is anticipated that this project will have significant socioeconomic benefits for Cyprus. These range from improving public safety to stimulating new product and service development.

 
This project if funded by the Research Promotion Foundation, Cyprus and the University of Cyprus
