Energy-Efficient Server Selection Algorithm forPeer-to-Peer (P2P) Systems

在信息系统中，为了实现绿色it技术，降低计算机和网络的总功耗是至关重要的。分布式系统上有各种各样的应用程序。在本研究中，应用分为计算、通信和一般类型的应用。在一般类型的应用程序中，计算和通信模块都被执行。我们定义了计算机的计算模型、传输模型和功耗模型，以执行每种类型的应用程序进程。在此基础上，我们提出了一种算法，可以选择一台计算机来执行每种类型的应用进程，从而既可以减少系统的总功耗，又可以减少每个进程的响应时间。

In information systems, it is critical to reduce the total electrical power consumption of computers and networks in order to realize green IT technologies. There are various kinds of applications on distributed systems. In this study, applications are classified into computation, and communication, and general types of applications. In the general type of applications, both of computation and com- munication modules are performed. We defined the computation model, transmission model, and power consumption models of a computer to perform each type of application process. Based on the models, we proposed algorithms to select one of computers to perform each type of application process so that not only the total power consumption in a system but also response time of each process can be reduced.
