DAYS Mobile: A Location based Data Broadcast Service for Mobile Users

Location dependent wireless data dissemination has become an integral part of our day-to-day activities. Most available applications are actually location aware which find restaurants, hotels, and millions of other points of interests (POI). Recent advances in global positioning systems (GPS) technology has led to the development of smart and efficient navigation systems with voice prompted turn by turn directions to the destination. Deployment of wireless broadband services like Evolution Data Optimized (EVDO) has motivated the development of ubiquitous data distribution systems or wireless broadcast of Location based Services (LBS). DAYS (Data in Your Space) Mobile discusses a broadcast based LBS which tends to decrease access latency [4] for location dependent data (LDD) when the number of mobile users is significantly large. We create a broadcast platform to disseminate commonly used LDD like weather, traffic, stocks, flight information, etc., and develop and deploy a java based mobile application in a mobile device which accesses the broadcasted LDD. Our experiments and results show that a broadcast based LBS can be highly efficient as compared to the present generation of request-response type LBS.
