Abstract: A peer-to-peer (P2P) system is composed of peer computers which are interconnected in overlay networks. Here, each peer computer can play both the roles of server and client. The P2P system is fully distributed and there is no centralized coordinator. The power consumption of each peer will vary accordingly. Here, the calculation of CPU utilization time is addressed. In the existing system, a reducing power consumption of web application is considered. A client peer issues a request to a set of server peers. On the receipt of a request, a server peer performs the request and sends the web pages to the client. An algorithm is developed to calculate the power consumption of each server peer. The minimum power consumed by the server peer is selected by the client. The proposed work is to consider the file transfer protocol (FTP) application. In the existing system, minimum power consumption is identified in the web applications. Here, the power consumption is measured in multi-CPU servers by using an algorithm and by comparing with an existing algorithm.
