2. 0700384_UK.PPT-2 Background Various video and infrared (IR) monitoring methods exist today to monitor and control access –Video monitoring –IR moving object detectors –IR tripwire paths We propose a new approach to intruder detection and location – a swarming sensor network

3. 0700384_UK.PPT-3 Basic Technology Many sensor “pebbles” connected in a very simple network Act as cueing nodes using an influential form of communications without protocols Swarming of pebble behavior in response to cue stimulation from pebbles Means to remotely monitor the sensor network

5. 0700384_UK.PPT-5 Elements of the Network Corporate Facilities Security Office Remote Receivers Sensor “Pebble Field”

6. 0700384_UK.PPT-6 Intruder Detection Corporate Facilities Security Office Remote Receivers Sensor “Pebble Field”

7. 0700384_UK.PPT-7 Intruder Detection via Microwave Signal Blockage All nodes operate on communications frequency Several nodes act as “illuminators” Corporate Facilities Security Office Remote Receivers Sensor “Pebble Field”

8. 0700384_UK.PPT-8 Commercial Applications Means to monitor security zones –difficult to counter –highly automated and relatively inexpensive Scalable from room size to many square miles –Examples: Offices  Industrial complexes Malls  Utility installations Office buildings  Military test ranges Existing designs provide a practical starting point for rapid prototyping
