An Integrated Power Consumption Model for Communication and Transaction Based Applications

In order to realize digital ecosystems, the total electric power consumption of computers and networks have to be reduced. In distributed systems, clients issue requests to servers and then servers send replies to clients. Here, application processes are composed of a pair of modules which mainly consume computation and communication resources, respectively. Based on the measurement of the power consumption of a server, we newly discuss a power consumption model of a server for applications. We propose an EPCLB (extended power consumption laxity-based) algorithm to select one of servers for applications so that the total power consumption of servers can be reduced. We evaluate the EPCLB algorithm in terms of execution time and power consumption compared with the traditional round-robin algorithm.
