Green networking in home and building automation systems through power state switching

Intention of this work is to investigate the opportunity and feasibility of more energy efficient networking in wired Home and Building Automation Systems, which have traditionally devoted a relatively little attention to this issue, especially if compared to wireless networks. This paper will propose a solution to address the problem by evaluating the introduction of power state switching in a real scenario and defining the concept of functional and spatial adjacency among packets. The impact of adopting such approach will be assessed through a simulation aimed at determining the best trade-off between energy and Quality of Service.
