Wireless sensor networks have been proposed extensively over the past several years as a means of alleviating instrumentation costs associated with structural health monitoring of civil infrastructure. However, low data throughput, unacceptable packet yield rates, and limited system resources have generally plagued many deployments by limiting the number of(More)
Low-power radio frequency (RF) chip transceiver technology and the associated structural health monitoring platforms have matured recently to enable high-rate, lossless transmission of measurement data across large-scale sensor networks. The intrinsic value of these advanced capabilities is the allowance for high-quality, rapid operational modal analysis of(More)
(2009) " Real-Time wireless vibration monitoring for operational modal analysis of an integral abutment highway bridge, " Abstract— Remote structural health monitoring systems employing a sensor-based quantitative assessment of in-service demands and structural condition are perceived as the future in long-term bridge management programs. However, the data(More)
Homeland security requires thorough monitoring of the nation's transportation infrastructure health. Discussed in this paper is research aimed at developing a smart wireless sensor network that is an efficient and practical health monitoring system and is also versatile for security monitoring strategies. At the core of such a system is an integrated(More)
With the increased demand placed on aging infrastructure, there is great interest in new condition assessment tools for bridges. The routine deterioration that bridges undergo causes a loss in the intended performance that, if undetected or unattended, can eventually lead to structural failure. Currently the primary method of bridge condition assessment(More)
The development of low-cost wireless sensor networks has resulted in resurgence in the development of ambient vibration monitoring methods to assess the in-service condition of highway bridges. However, a reliable approach towards assessing the health of an in-service bridge and identifying and localizing damage without a priori knowledge of the vibration(More)
Over recent years, there has been much interest in the use of low-cost wireless transceivers for communication of sensor data to alleviate the expense of widely distributed cable-based sensors in structural monitoring systems. However, while the number of unique wireless sensor platforms has continued to expand rapidly, the lack of success in replicating(More)
