03:50-04:50 PANEL:
Panelists: Blatt, Friedland, Haussecker, Papadopoulos, Pottie, Sayeed, Theriault 

Position statement: 5 minutes each, focusing on one of the following questions: 

1. (Theriault, Friedland, Sayeed) What can we sense using networks of distributed sensors (e.g. is CPA all we need to transmit)? What properties of targets should we sense? 

2. (Blatt, Haussecker) What is optimal placement/density of sensors for a given tracking or classification problem? What are the advantages/disadvantages of using simple, densely populated nodes versus powerful, sparsely deployed nodes? 

3. (Pottie, Papadopoulos) What are the tradeoff curves for power, communication bandwidth, and delay? How can a network of sensors adaptively allocate resources?
