Abstract

The aim of this study is to develop an open architecture platform for mobile-phone-centric ambient intelligence applications. The two main application fields are 1) local wireless sensor networks for health-related applications and 2) ubimedia, meaning digital content embedded in the environment. In the proposed architecture, a mobile phone acts as a central node hosting applications and connecting a local, e.g. sensor, network to back-end servers in the Internet. The technologies used in the architecture include Simple Sensor Interface (SSI) protocol, nanoIP, and lowpower short-range radios, e.g. Bluetooth Low Energy (formerly BTLEE), Radio-frequency Identification (RFID), 5 kHz inductive links, and impulse ultra-wideband (UWB). The sensor network architecture has been implemented and successfully demonstrated using several applications with commercially available mobile phones with add-on electronics. A system architecture, including both the hardware and software architecture, enabling mobile phones to read Ubimedia with sufficiently high data rates for multimedia applications is also presented. This architecture could also be used as a new type of high-speed wireless internet access.
