TL;DR: It is shown that the group key management service, using any of the three rekeying strategies, is scalable to large groups with frequent joins and leaves, and the average measured processing time per join/leave increases linearly with the logarithm of group size.

TL;DR: This paper studies the application of sensor networks to the intrusion detection problem and the related problems of classifying and tracking targets using a dense, distributed, wireless network of multi-modal resource-poor sensors combined into loosely coherent sensor arrays that perform in situ detection, estimation, compression, and exfiltration.

TL;DR: The key requirements of ExScal, the corresponding design of the hardware/software platform and application, and some results of the authors' experiments are overviewed.

TL;DR: A reset subsystem is designed that can be embedded in an arbitrary distributed system in order to allow the system processes to reset the system when necessary, and is very robust: it can tolerate fail-stop failures and repairs of processes and channels, even when a reset is in progress.
