Volunteer clouds are a prominent example, where participants join and leave the platform and collaborate by sharing their computational resources. The high dynamism and unpredictability of such scenarios call for decentralized self-* approaches to guarantee QoS. We present a simulation framework for collaborative task execution in volunteer clouds and propose one concrete instance based on Ant Colony Optimization, which is validated through a set of simulation experiments based on Google workload data. date: 2013-08-01 date_type: submitted institution: IMT Institute for Advanced Studies Lucca citation: Sebastio, Stefano and Amoretti, Michele and Lluch-Lafuente, Alberto A Computational Field Framework for Collaborative Task Execution in Volunteer Clouds.
