• Introduction
• Current status for :– Mote network– Main Application– PDA Application– Server Application– Web Application– Web Service– Database– System demonstration
• Project status update
What we will talk about?
Mote network
• Tested and functional
• Meets (almost) every requirement– Static mote startup / shutdown support
pending
• Additional feature– Ability to increase / decrease dynamic mote
radio range
Mote network – potential problems
• Corruption of data packets sent over radio– Very rare, but present
• Considering potential solutions:– Protecting radio packets with CRC– Implementation of safe communication
protocol
Mote server
• Propagation of mote network events to the PDA server
• Three main parts:– MoteIF– PDASignaller– MoteServerGui
MoteIF
• Application – level access point to the mote network
• Receives messages from the mote network, and forwards them to listeners
• Sends messages from applications to motes in network
PDASignaller
• Listens for messages
• On message receive passes it to the PDA server– Communication realized using RPC
