1. Web Service-Based Remote Monitoring System for Smart Home Space Sheng Cai Joshua Ferguson Xinhui Hu Wei Wu Project for CSE535 Mobile Computing

2. Outline 2 Conclusion Results Application Introduction System Structure

3. Introduction Smart Home Space –wireless sensor network deployed in home environment –monitoring the home space –query the specific type of data –control home appliance Motivation –remotely obtain the sensed data –retrieve the data pervasively –apply our system framework for extended functions

4. System Framework Home Space Sensor Home Gateway Internet Mobile User Web Service Database JDBC PHP Mysql Tinyos JAVA Web Browser

5. System Framework Leverage our previous knowledge to pervasive monitoring Web service –user based, require user name and password to login –generate user’s request for specific type of data, e.g. temperature –query the requested information and display it Home gateway –handoff between home network inside the home space and internet outside –combined with database, mysql –functions of database store the data transferred from sensors send user’s request

6. Example 1. user login 2. choose the first option 3. choose data type 4. request generation

7. Example 1. user login 2. choose the second option 3. browse the sent request Two steps: 1.Value attribute is firstly set to be NULL. 2.After obtaining the value from sensors, NULL value will be updated.

8. Application1 Data Gathering Schemes Reduce sensing times finally reduce energy consumption.

9. Results Energy-aware data gathering with dynamic frequency scheme

10. Application2 Temperature Control Adaptive and Intelligent: –Using the control orders and the owner’s custom in the database, the controller could automatically executes to make the environment to fit owner’s customs.
