“…In contrast to CXFS and LaneFlood, G1M does not need to collect network topology when performing one-to-one transmission. Unlike LWB, in which nodes send and receive information on a periodic basis, eLWB [6] is an event-triggered wireless sensor system that enables low-power event detection and response. The Harmony [7] protocol takes advantage of concurrent transmissions and embeds techniques to ensure reliable and timely delivery of data in the presence of high channel congestion.…”

Recent studies have shown that concurrent transmission with precise time synchronization enables reliable and efficient flooding for wireless networks. However, most of them require all nodes in the network to forward packets a fixed number of times to reach the destination, which leads to unnecessary energy consumption in both one-to-one and many-toone communication scenarios. In this letter, we propose G1M address this issue by reducing redundant packet forwarding in concurrent transmissions. The evaluation of G1M shows that compared with LWB, the average energy consumption of one-to-one and many-to-one transmission is reduced by 37.89% and 25%, respectively.

“…A wireless sensor platform, the TelosW platform [17], was upgraded from the TelosB platform using an ultra-low-power acceleration sensor as a wake-up mechanism with the integration of wake-on radios. Sutton et al, [18] developed an event-detection system with low power wake-up receiver that used 1/1000 of the power of the designs presented in [17]. Bischoff et al [19] used an event-detection-based wireless sensor system for railway bridge monitoring using a commercial accelerometer with a triggering function.…”

Wireless sensor networks (WSNs) are promising solutions for large infrastructure monitoring because of their ease of installation, computing and communication capability, and cost-effectiveness. Long-term Civil structural health monitoring (SHM), however, is still a challenge because it requires continuous data acquisition for the detection of random events such as earthquakes and structural collapse. To achieve long-term operation, it is necessary to reduce the power consumption of sensor nodes designed to capture random events and, thus, enhance structural safety. In this paper, we present an event-based sensing system design based on an ultra-low-power microcontroller with programmable event-detection mechanism to allow continuous monitoring; the device is triggered by vibration, strain, or a timer and has a programmed threshold, resulting in ultra-low-power consumption of the sensor node. Furthermore, the proposed system can be easily reconfigured to any existing wireless sensor platform to enable ultra-low power operation. For validation, the proposed system was integrated with a commercial wireless platform to allow strain, acceleration, and time-based triggering with programmed thresholds and current consumptions of 7.43 and 0.85 mA in active and inactive modes, respectively.

“…Teizer and Castro-Lacouture [13] adopted WSN to collect the realtime status of personnel, materials and equipment at the construction sites, and improved the monitoring and management efficiency. Sutton et al [14] realized remote monitoring of construction projects based on WSN, and achieved functions of safety monitoring, quality monitoring and building energy saving. Murty and Shrestha [15] combined the CI system with the enhanced RFID positioning technology to realize multi-parameter monitoring of key parts of bridge structures and applied it to the risk warning of bridge structure damages.…”

For most construction projects, the complex engineering environment, the backward data collection technology, and the unreasonable monitoring network have resulted in many problems in monitoring data such as lots of noise and missing data items, therefore, it is of great significance to study the safety monitoring system of construction projects based on wireless sensor network (WSN). For this reason, this paper proposed a construction safety monitoring and evaluation (CSME) model based on multi-sensor fusion. First, the system structure and data flow model of the construction safety monitoring system were constructed; then, combining with a multi-sensor deep fusion system which was built on physical and information systems, this paper designed a spectrum sensing algorithm for sensor signals within the construction area. After that, tempo-spatial correlation analysis was conducted on the monitoring data, and a multi-sensor monitoring network joint sparse (MSMN-JS) model was constructed, which realized reconstruction of missing data items. At last, this paper used experimental results to prove the application value of the algorithm model to the safety monitoring and evaluation of construction projects.
