Deployment Knowledge

• What is deployment knowledge?
• How are sensors deployed?
• Are they uniformly randomly distributed?
• How to model deployment knowledge?

Positions and Challenges

• Our Positions
• Not all deployments are uniformly random.
• Deployment knowledge is power.
• Our Challenges
• What else can we do with the deployment
  knowledge?
• Are there other knowledge that can be used?
