Recent research on Low Power Wide Area Network (LPWAN) technologies which provide the capability of serving massive low power devices simultaneously has been very attractive. The LoRaWAN standard is one of the most successful developments. Commercial pilots are seen in many countries around the world. However, the feasibility of large scale deployments, for example, for smart city applications need...
The dense instrumentation of future smart buildings enables the implementation of advanced control techniques which are aimed at the dual objectives of energy efficiency/cost savings and occupant comfort. One of the essential functions and prerequisite consists of robust dynamic occupancy detection and prediction which allows improved estimation of active thermal zones and internal loads, as compared...
LoRa, an emerging wireless technology, is examined for long range communication performance in a large area. Although LoRa shows good performance for long-distance transmission in the countryside, its radio signals can be attenuated and interfered with by buildings, trees and other signal sources. In urban areas, our observation shows that LoRa requires a dense deployment of LoRa gateways to ensure...
Wireless sensor networks are a cheap and versatile solution for monitoring various environments. There are a number of such applications used worldwide to monitor areas in which human access is hard or near impossible. These applications are mainly used by government organizations or for research purposes, while standardized or commercial applications are still under development. They seldom focus...
With the rapid development of wireless communication technology, people's life has undergone great changes. In recent years, the comfort and safety of the building environment have become a universal concern. However, building fire is the greatest threat to building safety. In consideration of the current issues on building security, the design applies the important part, the wireless sensor network...
This paper presents a low cost approach for structural and seismic monitoring with the aim of developing an Early Warning System. The proposed architecture is based on a customized network of multi-sensor nodes equipped with inertial sensors and a microcontroller architecture aimed to signal processing and the management of data transfer. Results presented highlight the suitability of the developed...
During its whole service life, a building can be subjected to operational and environmental forces usually present, or to episodic seismic loadings (earthquakes). An automated smart building is a house capable of self-monitoring in order to signal the need of maintenance, when a reduction in performance levels is detects, or to signal the need of action if there are some structural problems. One of...
During Urban Search and Rescue (USaR) operations in collapsed buildings, once the entrapped victims are located the extrication starts. The latter is always time consuming whilst in most cases medical monitoring and support of the victim is needed. Monitoring vital signs of victim is quite important but due to the particular post-collapse conditions of the building (fires, gas leaks, tremors/instability),...
The availability of context aware scenarios is a compulsory requirement in order achieve efficient Smart Health services. In this work, the deployment large scale wireless sensor networks to enable interactive scenarios in order to provide Health services will be analyzed by means of deterministic 3D ray launching techniques in order to consider topo-morphological impact in services to be provided...
The traditional fire monitoring system for historical building adopts wired mode which can do a lot of damage to the building. In order to solve this problem, a wireless fire monitoring system is designed based on the CC2530. The sensor node and the routing strategy are implemented in this system. The sensor nodes sense the temperature, light and smoke. Then they transmit this information to the coordinator...
Buildings consume a large portion of electric energy worldwide and they are also expected to actively participate in demand response under the concept of smart grid. A key premise for efficient energy utilization is energy measurement and loads control. In this paper, a Web-based Energy Management Application (WEMA) is designed and implemented based on our previous work. This application runs on a...
Structural Safety of buildings is a major issue. The ability to monitor the behavior of the buildings which are subject to seismic acceleration or anthropogenic activity may reveal whether there is or has been created a structural problem in each construction. Public buildings, especially schools are even more of critical importance not only because each day they are visited by hundreds of children...
In recent years, Wireless Sensor Network(WSN) is considered as a potential solution for home automation because of its reliability, low-cost, low-power consuming characteristics. Several researches have been carried out using WSN for home automation, however most studies have been experimented in small houses or in one storey of a building. There has been little discussion about design and implementation...
Human life has changed since energy scarcity and climate change. We consider that building of high energy consumption. In this study, we propose a method to solve this problem by ZigBee Wireless Sensor Network (WSN). We use ZigBee WSN and Hall current transducer to monitor power consumption of load for each sensor node. If the power consumption of load is higher than maximal power, the ZigBee WSN...
This paper presents a monitoring system of building electricity using IPv6 to establish a network. This smart metering system consists of three parts: the host software, the network and the sensor nodes. The network, whose data transmits via Zigbee wireless communication protocol, is designed based-on IPv6 protocol, and builds the IPv6 protocol on IEEE 802.15.4 wireless network. The Sensor node has...
Structural health monitoring (SHM) is of great significance for ensuring the using functions, safety operation of buildings and extending service lifetime of buildings. The structural damage detection is the main work of the structural health monitoring. In this paper, we proposed a new online structural damage detection method called N-stage Kalman Filter Algorithm (NS-Kalman). Its main idea is to...
Residential building explosion caused by gas leak takes place every year. The explosion leads to a lot of injures even dead since it usually results in the partial collapse of the building. An automated approach to detecting the gas leak to keep the residents safe is thus of utmost importance. In this paper, we present the design of Gas Mon, a wireless sensor network system for gas leak monitoring...
In this paper we propose an agent-based approach for the integration of building networks (BNs) and body sensor networks (BSNs). Such an integration has the potential to enable a novel set of smart environments for ambient assisted livings further enhancing the concept of smart buildings. Specifically, inhabitants of buildings who are equipped with a BSN can expose their real and virtual sensed data...
