Energy-Aware Middleware

Computer networks have become a critical part of our society as we, as users, need our networked world to function continually and at full capacity. One of the basic and often overlooked factors required for such qualities is that of energy. Energy consumption is a non-functional property that needs to be addressed by a network manager, at the more specialized level of middleware. In this paper we model resource energy using a middleware language called MIDAS. This language is resource-centric and based on a formal framework for location-aware computing. By taking a device energy into consideration we reach a new approach regarding the resource locations. We distinguish between two networks types and further distinguish software resources from hardware devices. We obtain a unitary approach of considering co-located resources that can be exploited for efficiency in context-oriented applications. Hence, better availability and reliability of the energy-aware MIDAS resources can be ensured.
