this paper proposes an efficient network architecture to improve energy consumption in wireless sensor networks (wsn). the proposed architecture uses a mobile data collector to a partitioned network. the mobile data collector moves to center of each logical partition after each decision period. the mobile data collector must declare its new location by packet broadcasting to all sensor nodes. h...

The development of smart grids makes possible the introduction of dynamic electricity rates, with prices changing each hour. Dynamic rates can reflect the temporal dependency of supply and demand for electrical power and network capacity, thus avoiding load peaks and promoting the use of fluctuating renewable energy sources. We present a simulation model that studies the electricity demand for ...

Accurate prediction from electricity demand models is helpful in controlling and optimizing building energy performance. The application of machine learning techniques to adjust the electrical consumption buildings has been a growing trend recent years. Battery management systems through allow control supply, adapting possible changes that take place during day, increasing users’ comfort, ensur...

With advances in energy metering, communication, and analytic software technologies, providers of Energy Management and Information Systems (EMIS) are opening new frontiers in building energy efficiency. Through their engagement platforms and interfaces, EMIS products can enable energy savings through multiple strategies including equipment operational improvements and upgrades, and occupant be...

Energy carriers are one of the most important inputs in the agricultural sector. These inputs have been the foundation of the development and transition of the agricultural sector from the traditional stage to the industrial stage. The energy per capita marginal consumption in Iran’s agricultural sector is 3.2 times greater than its global average. Therefore, it is essential to save and optimal...

We consider two problems in the design and operation of energy-efficient buildings. The first is the prediction of energy consumption of a building from that of similar buildings in its geographical neighborhood. The second problem concerns the localization of faults in building sub-systems with a focus on faults that lead to anomalous energy consumption. For both problems, we propose algorithm...

N etworks are one of the most significant developments in computing and a hallmark of modern society. However, along with increasing efficiency and productivity, both at home and in the workplace, networks have costs. One cost is the additional energy that electronic devices consume when attached to networks. Recent studies indicate that the economic and environmental impact of such energy use ...

Sustainable facilities management (SFM) opens the door of opportunity for companies to evaluate the quality of resources and environment management at their facilities. It enables the principles of sustainable development. There is still inefficiency in quantitative research of integrating environmental factors, particularly multi-source data, to monitor and control complicated systems in build...
