Uncertainties, Sensor Motes, Trust Issues

This Works in Progress department features three submissions. The first focuses on the uncertainties associated with identifying nodes that are faulty or malicious. The second addresses the challenges of programming in the decentralized programming environment of sensor motes. Sensor motes are limited-functionality devices-they have limited memory, computational capabilities, and power resources. The final work in progress discusses a project to address pervasive computing trust issues in healthcare environments.
