Ranking Energy-Aware Services

Green computing has the ultimate goal of eliminating technological waste. In the last decade, there has been a dramatic increase in the interest in green computing. One aspect of technological waste is energy consumption. In computing, this includes the energy consumed by both hardware and software. A service-oriented system, consist of distributed services. The energy consumed by a service request is proportional to the distance between the service provider and requester. This paper is interested in enabling SOA to be energy-aware. The service publication, discovery, selection and ranking, should consider energy consumption. This is achieved by introducing an extended service-oriented architecture, a new service definition model and a novel ranking algorithm that consider energy-consumption in the ranking process.
