Multilayer approach to cost-efficient home automation

This paper describes an approach to a full vertical smart building solution. The concept relies on identification of distinct layers, selection of optimal technologies for each, and their seamless integration into a unified service. The solution uses low-cost, energy efficient Zigbee for the most massive device layer, embedded solution for the layer local intelligence resides in, and enterprise technologies for the cloud. The experiments and measurements show that the selected technologies ensure adequate feature distribution and responsiveness across all layers. User test proves the interactivity is maintained across the full vertical.
