Task Assignment Algorithm Based on Trust in Volunteer Computing Platforms

Abstract: In volunteer computing (VC), the expected availability time and the actual availability time provided by volunteer nodes (VNs) are usually inconsistent. Scheduling tasks with precedence constraints in VC under this situation is a new challenge. In this paper, we propose two novel task assignment algorithms to minimize completion time (makespan) by a flexible task assignment. Firstly, this paper proposes a reliability model, which uses a simple fuzzy model to predict the time interval provided by a VN. This rel… Show more

“…The works [22,23] have been described before, so we do not reiterate them here. Xu et al [24] proposed two algorithms with the goal of minimizing the maksepan of tasks, which is different to our goal. In summary, the existing algorithms cannot solve the dynamic task assignment problem under the disturbance of availability time, and the goals of existing algorithms are different from our algorithm, which aims to maximize the benefit of VCPs.…”

“…For the reliability, there are also many prior works [22][23][24]; however, their optimization goals are different from ours. The works [22,23] have been described before, so we do not reiterate them here.…”
