Demonstration Scenario for SOWN

Approximately 1000 motes placed relatively uniformly over 100x1000m grass and scrub brush area encompassing a dirt road.  The network will be roughly divided into 10 sections with roughly 100 motes each.  In each section, a relay is in charge of commanding sensor operation and retrieving information about environmental events.

 In this demonstration scenario, there are two types of network sections. 

• The first type is called a tripwire section, in which sentry-based surveillance is provided.  We expect 30 to 40% of the motes in these areas to be sentries and they will provide timely detection.

• The second type of section is called a dormant section, in which no surveillance is provided. For the dormant sections, all nodes are in the dormant state, until there is a wake-up call from any tripwire section.
