—Observing the environment is the raison d’ ˆetre of sensor networks, but the precise reconstruction of the measured process requires too many messages for a low power sensor ...
— Recent studies on wireless sensor networks (WSN) have shown that the duration of contacts and inter-contacts are power law distributed. While this is a strong property of these...
—This paper highlights a series of proven concepts aimed at facilitating the design of next generation systems. Practical system design examples are examined and provide insight ...
If we hope to automatically detect and diagnose failures in large-scale computer systems, we must study real deployed systems and the data they generate. Progress has been hampere...
Firms invest heavily to develop on-line cooperative systems in the hope of creating unique value in the minds of their customers. However, when system use begins to decline, firms...
