Self Configuring Sensor Networks

• Most important attribute of a sensor network
• Nodes organize into an ad-hoc network
• Localize themselves in space and time
• Calibrate their sensors

Ad-Hoc Deployment
Operate in the presence of obstacles
Rapid Infrastructure Setup
6
Our Approach to Node Localization

• Vertical cut-through approach that examines all
  system aspects
• Care about physical layer effects
• Multipath, interference, obstacles
• Low power distributed operation
• Realistic application scenarios
• Multihop operation is key!!
