1 THE INSTITUTE OF ELECTRONICS, INFORMATION AND COMMUNICATION ENGINEERS TECHNICAL REPORT OF IEICE Bluetooth Low Energy Wi-Fi Designing Feature of Generating and Storing Common Pass-by Data in Pass-by Framework Arisa HAYASHI, Shinsuke MATSUMOTO, Sachio SAIKI, and Masahide NAKAMURA Graduate School of System Informatics, Kobe University, Rokkodai 1-1 Nada, Kobe, , Japan Abstract In our previous work, we have been proposed a pass-by framework in order to facilitate development of pass-by system which uses proximity information of mobile devices. The framework isolates pass-by detection technologies and applications of pass-by information. This isolation provides developers to reuse common pass-by data that retrieved by various proximity detection technologies. The goal of this paper is to realize and design the pass-by framework. To achieve the goal, we discuss how the framework generates and stores pass-by data. First, we organize some specific requirements for converting, generating and storing the data. Based on the requirements, we re-design detailed architecture and identify responsibilities of each component in the framework. Finally, we organize s from the perspectives on pass-by detection and pass-by data application. Key words Pass-by framework, neaby detection, mobile devices, Bluetooth Low Energy, Wi-Fi 1.
