Sensor Virtualization for Enabling Novel Services

The paper presents a model for the virtualization of a wireless sensor network in a smart home application for energy consumption monitoring. By correlating physical sensor data with information on home's design, sunrise and sunset time according to day of year, time of day and weather data, novel services for consumed power statistics and efficiency of use of natural light were developed in the virtualized environment. Based on this model, distributed applications were developed to implement analysis of energy consumption over large scale areas. We detail the solution implementation based on the OpenSHS simulator and NodeRed.
