Trust is becoming an increasingly important issue in large-scale distributed systems. Especially self-managed systems from the Autonomic and Organic Computing domains consisting of several cooperating entities have to rely on an automated estimation how reliable and trustworthy potential cooperation partners are. In this paper, we introduce a novel concept to represent trust among those entities....
For an application in public-resource computing environments, providing reliable scheduling based on resource reliability evaluation is becoming increasingly important. Most existing reputation models used for reliability evaluation ignore the time influence. And very few works use a robust genetic algorithm to optimize both time and reliability for a workflow application. Hence, in this paper, we...
This paper addresses the inherent unreliability and instability of worker nodes in large-scale donation-based distributed infrastructures such as peer-to-peer and grid systems. We present adaptive scheduling techniques that can mitigate this uncertainty and significantly outperform current approaches. In this work, we consider nodes that execute tasks via donated computational resources and may behave...
