4 Non functional requirements non functional requirements 1. The system should be open source. 2. Bugs/function point < 5 3. Available time >99% 4. The system should adopt the OGC sensor. Use Case Specification Use Case Name Manually Control Brief Description Provide a control interface for user to close all lights Flow of Event Use Case Scenario Basic flow: 1. User presses the lights off button 2. User confirms this instruction 3. Turn off all the lights and give feedback to user. The user presses the lights off button, then the system will ask user to confirm this instruction. After user confirming, the system turn off all the lights of the house, and give feedback to user. 4

5 Use Case Specification Use Case Name Sound Control Brief Description Flow of Event Use Case Scenario Provide a function to enable the system to control the lights according to signal of sound sensors. Basic flow: 1. Sound sensors send the signal from rooms 2. The system turn on the lights of rooms. Alternative Flow: 1. If the signal is from guest room, turn on the lights of guest room 2. If the signal is from bedroom, turn on the lights of bedroom 3. If the signal is from bathroom, turn on the lights of bathroom 4. If the signal is from kitchen, turn on the lights of kitchen The system gets the signal, and check the signal is from which room(guest room, bedroom, bathroom,or kitchen), then the system opens the lights of that room Use Case Specification Use Case Name Video Control Brief Description Flow of Event Use Case Scenario Provide a function to enable the system to control the lights according to signal of video sensors. Basic flow: 1. Video sensor send the signal about person coming in. 2. The system open all the lights of house. Alternative Flow: 1. After the system gets the signal from video sensor, the system finds the person inside the house, then ignores this signal. The video sensor detect the person is coming in, then it send the signal to video control. Video control check whether there is person inside the room, if not, opens all the lights. 5

6 Use Case Specification Use Case Name Timer Control Brief Description Flow of Event Use Case Scenario Provide a function to control the lights according to the time. Basic flow: 1. System clock send time to the timer control system 2. The system check the time and turn on/off all the lights Alternative Flow: 1. If the time value is 7am, turn on all the lights 2. If the time value is midnight, turn off all the lights The timer control system gets the time from system clock, and check the value. If the time is 7am, turn on all the lights, and if the time is midnight, turn off all the lights. Use Case Specification Use Case Name Light on Brief Description Provide a function to turn on the light Flow of Event Use Case Scenario Basic flow: 1. Find and check the light 2. If it is off, turn it on The light on function is used to turn on a certain light. If the light is on, do nothing; otherwise, turn it on. 6

7 Use Case Specification Use Case Name Light Off Brief Bif Description i Provide a function to turn off the light Flow of Event Use Case Scenario Basic flow: 1. Find and check the light 2. If it is on, turn it off The light on function is used to turn on a certain light. If the light is off, do nothing; otherwise, turn it off. 3 Part Three Service Modeling Services architecture, Contract, Interface 7

Criteria of Web Service Framework: ease of development, deployment, licensing policies, error handling capabilities, performance, integration with IDEs, standards compliance, memory footprint, interoperability etc 14
