What we will talk about?

23-04-19 6

Introduction• General requirements

• Divided in 5 parts• Main application - basic functionality• Mote network - communication between motes• PDA Application - gives visitor multimedia content• Web Application - view exhibition from home• Database - store information

Main aplication

• Has five main functions– Staff management– Visitor registration– Floor plan and mote administration– Exhibit content administration– Mote management

• Technologies– .NET framework 2.0– C#

Staff management

• This part allow us to register new users– Two different types of users

• Administrator– Able to see all main application options (possibilities)

• Staff– Can only register new visitors and see visitors positions

in a museum

• Also allow us to change user details– Name, password ....

• Or delete existing user

Floor plan and mote administration

• Allow us to present mote deployment in museum space (using preloaded map of the museum)

• Drag and drop functionality will make adding removing and relocating the motes easy

• Displayes signal coverage

• We will see visitors current positions in a museum and will be able to see attendance for each exhibit

Exhibit content administration

• Part for adding deleting and modifying exhibit related content

– Allow administrator to chose video and/or static content that will be sent to visitors PDA

– Creates links in database that will be used in data streaming module

Visitor registration

• When visitors come in the museum this is where we will register them– Using some personal data (e-mail) but never

storing it, and links it with PDA IP address and mote ID

– taking care of visitors privacy– Allows merging of data for previously visited

exhibitions

• Administrator can delete information on visitors

Vision of the main application

Mote management

• Allows administrator to power up and shut down motes in the museum

– Power up in the morning when museum opens

– Shut down at the end of work time– Power up/shut down on will

Mote Control

Mote network requirements

• Detect visitors at every exhibit

• Identify visitor

• Identify exhibit

• Inform the rest of system about this

• Allow system to control network (start up / shut down)

Mote network - overview

Three mote classes:• Static motes

– At every exhibit stand– Larger radio range

• Dynamic motes– With museum visitor– Smaller radio range

• Base mote– Connected to the server computer– Bridge between hardware and software part of the

system
