| Outline of Final Research Achievements |
In peer-to-peer (P2P) systems, application processes have to be reliably performed in presence of server faults. One way to make an application service fault-tolerant is that multiple replicas of each application process are performed on multiple peers. On the other hand, a larger amount of electric energy is consumed since multiple replicas of each application process are performed on multiple peers to make application services fault-tolerant. It is critical to discuss how to realize not only fault-tolerant but also energy-efficient P2P systems to provide application services. In this study, the computation model and power consumption models of a peer to perform computation processes are defined. Based on the models, the energy-efficient server selection algorithms to select multiple servers for redundantly performing replicas of each computation process are proposed.
