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
