Person Wide Web: Active location based web service architecture using wireless infrastructure

Due to the recent advancements of Wi-Fi technologies, people can receive various types of data services via their portable devices such as laptop, smart-phone, and PDA. Especially, as the localization technologies are well developed, the LBS (Location Based Service) is recognized as a promising technology in the upcoming ubiquitous era. In most of LBS applications, users generally tend to visit shops, restaurant and public facilities in his surroundings. To exploit this feature, we propose Person Wide Web (PWW), a new type of location based web service architecture that effectively recognizes the location specific web resources to the mobile device user based on his geographical position. Among so-many resources in the WWW, only the things closely located to the user, make up his PWW. By using the PWW, various location specific data services such as shop advertisement, restaurant menu, and discount coupon, are expected to form a new type of business model in which marketers can actively promote the mobile device users to gladly use their services. We implemented a prototype of PWW system on Android platform and saw that our prototype has reasonable performance on service establishment and message delivery time. We believe the PWW has a potential to open up a new market area of provider triggered wireless data services.
