IndeedNET System Architecture : IndeedNET System Architecture Zigbee Network -----Zigbee Coordinator -----Zigbee Local Controller -----Zigbee Enabled Home Appliances Home Portal Internet Remote Controller Remote control Local control


Zigbee Home Network: Zigbee Home Network The Zigbee network is responsible for: Be responsible for building and maintaining devices communications Collect devices information in term of user requests Manage devices according to user settings


Zigbee Home Network Architecture: Zigbee Home Network Architecture


Two-way Communications: Two-way Communications Two way communication is required between the: Home Coordinator & Home Appliances Home Coordinator & Home Controller Home Controller & Home Appliances No communication between home appliances


Identify Zigbee Network Devices: Identify Zigbee Network Devices Zigbee uses a 16-bit network address or /and 64-bit unique IEEE address to locate all Zigbee devices including coordinator, router and end-device. Zigbee uses endpoints to distinguish different services provided by the appliances, e.g. extension socket.


Individual sensor/actuator identification: Individual sensor/actuator identification Sensors: Temperature Light Humidity Smoke Actuators: Light switch Radiator valve


Local Network Control/Communication Simulation: Simulate two-way communication between a local controller and a Zigbee device (LED) Demonstrate the local control function Local Network Control/Communication Simulation


Simulation Setup and demonstration: Simulation Setup and demonstration Simulation Devices -----Zigbee Home Coordinator -----Zigbee Home Controller -----Zigbee Home Appliances


Remote control/communication simulation: The architecture we propose for remote control of the indeedNET project is illustrated below: Remote control/communication simulation


Slide14: Remote Control Development Stages The proposed architecture consists of five main stages: Implementation of a Home Gateway to Internet enable a Zigbee Network using a personal computer. Replacement of the personal computer based Home Gateway with an embedded device. Development of a Virtual Home for monitoring the security and safety of actions. Integration of the Virtual Home with the Home Gateway Design and Implementation of a user friendly interface


Slide15: Stage 1 Development A connection between the internet and Zigbee network has been achieved using the following architecture:


Slide16: Stage 2 Development The next stage in development requires the replacement of the personal computer in the architecture with an embedded device.


Slide17: Stage 1 Implementation (1) The first stage of development has been implemented and is illustrated below: Zigbee Node showing switched of LED Mobile phone used to access home menu


Slide18: Stage 1 Implementation (2) The first stage of development has been implemented and is illustrated below: Menu showing current state of LED Menu showing LED being switched on. Zigbee Node after the LED has been switched on.


Work plan for next three months: Work plan for next three months Select wireless sensors Design wireless actuator (light switch, and radiator valve?) Design a local controller Design an embedded home server. Start to consider routing algorithm and energy saving control algorithm
