The emergence of smart grid technology is offering a unique opportunity to improve power management in intelligent buildings through the integration and optimization of distributed energy resources and loads. In this paper, the interactions of multiple intelligent buildings in the context of energy market, as well as distributed energy generation and storage facilities, is considered. Within a time...
In this paper, a discrete version of weighted centroid localization algorithm (dWCL) is proposed for a wireless-sensor-network-based indoor positioning system. Under this architecture, a wireless device can estimate its own position based on the location information of connected wireless sensor nodes in the network. Unlike other weighted centroid localization algorithms, dWCL classifies the sensor...
Typical low cost light sensors used in modern day buildings have an error of up to 40%. To achieve intelligent lighting control for intelligent energy management, illuminance sensor nodes need to have less than 5% error. In order to realize such sensors, high accuracy illuminance sensors of error less than 3 % are proposed to be integrated with high resolution Analog to Digital Converters (ADC). Subsequently,...
Accurate prediction of received signal strength is pivotal to reliable wireless communications. Unfortunately, wireless signals are often subject to random attenuation due to the environment surrounding the receivers. Shadowing loss, one of the main degradation factors, is well known to exhibit correlation when two wireless links are in proximity. In this pa-per, we study the features of two existing...
This paper presents a prototypical implementation of WSN-based daylight-responsive lighting and shading systems control in buildings that utilizes real-time sensing. This system can control the position of window blinds and the states of the luminaires to achieve the desirable visual comfort and energy efficiency based on the weather conditions and occupant activities. We first present the system...
Distributed Energy Resources (DER) are one of the distinguished features of Smart Grid. A combination of small-scale energy generator and storage unit can produce energy to serve the associated load, while at the same time store or sell excessive energy. Assuming there is an energy surplus, the system can choose to sell a portion of its available energy to the market. In this work, an oligopoly model...
Accurate prediction of received signal strength is pivotal to reliable wireless communications. Unfortunately, wireless signals are often subject to random attenuation due to the environment around the receivers. One of the degradation factors that contributes to such loss is shadowing loss. It is well known that the shadowing losses of two nearby radio links are correlated. In this paper, we study...
