  10. Contents • Cellular Phone • Architecture • BREW • Power Consumption • Cellular Phone with Sensors • Sensor • Roles of Cellular Phone

  11. Sensor • What it senses • Home Monitoring • Health Monitoring • Environment Monitoring • Habitat Monitoring • Earthquake Monitoring • Battlefield Monitoring Sensors exist everywhere Monitoring of physical world & its phenomena • Additional Features • Data Processing • Communication • within Low-Power Constraints

  12. Cellular Phone • Main Function • Mobile Phone to connect people • Additional Features • Message Service • Camera and Camcorder • Multimedia Playback • with powerful computing and infrastructure-based network • Battery-operated • Roles for Sensors • A bunch of sensor nodes • A central node or a proxy server for sensor network • A terminal to human for sensing data

  13. A. Cell Phone as a Sensor • To collect, to process, and to distribute data around people • Home Care • scan environmental data and forward it to care center • e.g.) check the gas leakage or poisonous material • Health Care • sense user’s health status and update/keep it. • e.g.) keep the heart rate or blood sugar rate for diabetics • Emergency Care • catch the emergent situation around people and scan/send data • e.g.) send rescue calls and captured data like picture

  14. A-2. Health Care • People want to check their health simply • LG KP8400 : Diabetics Phone • Blood Sugar Testing Phone • place a strip of testing paper located near battery • place a drop of blood on the end of the strip • get a reading from the phone • upload to an online database for later retrieval  Mobile Handset provides tools to check our health status and to keep or accumulate it

  15. A-2. Health Care (cont’) • What else for heath care? • Very basic but important health care services • NONIN Onyx 9500 : Digital Finger Pulse Oximeter • Read data over fingertip • Real-time information on Heart-Rate and Blood Oxygen Saturation Level  Simple devices for health care can be converged into mobile phones to check the health by user

  16. A-3. Emergency Care • Cellular phone carries rescue button call for safe • Curitel PG-L5000 – SOS Phone • Emergency Button Call • Call at three saved numbers • Take two pictures and send them • Inform others of the position using GPS  Mobile Handset senses emergent data

  17. Sensor Network Cellular Network B. Cell Phone as a Proxy • To use computing power and communication ability of cell phones for sensor network like a Proxy or a central node • Offloading technology • CPU:1s MHz in Sensor VS 100s MHz in Cell Phone • e.g.) sensor captures images and cell phone encodes/encrypts them and transmits them.

  18. C. Cell Phone as a Terminal • A terminal to human for sensing data • User can get information from sensor network immediately after requesting • An interface to human for information • User can collect preferred data through cellular phone

  19. C–1. Security • Cellular phone scans user’s fingerprint • LG LP-3800 with Fingerprint Scanner • AuthenTech sensor for fingerprint recognition • Locked for unwanted user to use the phone  Mobile Handset recognizes unique data for personal security

  20. C-2. Code Interface 1 2 • Colorzip.com : "ColorCode" - an interface connecting you to online contents • Media provides ColorCode • User camera on phone recognizes it • Server provides contents to client • User enjoys the contents  Mobile Handset provides an interface like camera to read and process data 4 3

  21. Wrap-up • Cellular Network might be a huge-covering and very potential Sensor Network. • More Friendly and Closer to Human Being • Mobile Handset has an interface for sensing data and functionalities of computing and communication
