An Efficient Services Placement for Optimizing the Energy Consumption in Volunteer Cloud Computing

Concurrency and Computation: Practice and Experience, Volume 37, Issue 3, 1 February 2025.
ABSTRACT Volunteer Cloud computing, like traditional Cloud computing, has gained significant importance due to its ability to harness resources from individual personal machines, contributed voluntarily by their owners. In this paradigm, personal machine resources are shared voluntarily by their owners.
