From agreement problems to replicated software execution, we frequently find scenarios
with voting pools. Unfortunately, Byzantine adversaries can join and collude to distort the …

MapReduce is a promising approach to support data-intensive applications on Volunteer
Computing Systems. Existent middleware like Bit Dew allows running MapReduce …

P2P systems are used to provide distributed storage, file sharing, video streaming,
distributed gaming, and other applications based on the collaboration of participating peers …

Open Distributed Systems, be it the Internet, peer-to-peer systems, e-commerce systems,
Desktop Grid Systems, wireless sensor networks, or vehicular ad-hoc networks, have …

A common technique for result verification in grid computing is to delegate a computation
redundantly to different workers and apply majority voting to the returned results. However …

We propose a mathematical model of a desktop grid computing system that solves tasks with
two possible answers. Replication is used in order to reduce the error risk: wrong answers …

Many grid-computing systems adopt voting-based techniques to resist sabotage. However,
these techniques become ineffective in grid systems subject to collusion behavior, where …

We consider a computing system where a master processor assigns a task for execution to
worker processors that may collude. We model the workers' decision of whether to comply …

With the rapid growth of Internet of Vehicles (IoV) applications and the advancement of edge
computing, resource-limited vehicles (and other IoT devices) increasingly rely on external …

While the mechanism of reputation aggregation proves to be an effective scheme for
indicating an individual's trustworthiness and further identifying malicious ones in mobile …
