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. A bunch of sensor nodes B. A central node or a proxy server for sensor network C. A terminal to human for sensing data

13 A. Cell Phone as a Sensor To collect, to process, and to distribute data around people 1. Home Care scan environmental data and forward it to care center e.g.) check the gas leakage or poisonous material 2. Health Care sense user’s health status and update/keep it. e.g.) keep the heart rate or blood sugar rate for diabetics 3. 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 1)place a strip of testing paper located near battery 2)place a drop of blood on the end of the strip 3)get a reading from the phone 4)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 1)Call at three saved numbers 2)Take two pictures and send them 3)Inform others of the position using GPS  Mobile Handset senses emergent data

17 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. Sensor Network Cellular Network

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  Colorzip.com : "ColorCode" - an interface connecting you to online contents 1) Media provides ColorCode 2) User camera on phone recognizes it 3) Server provides contents to client 4) User enjoys the contents  Mobile Handset provides an interface like camera to read and process data 12 34

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
