Wireless sensing technologies have been drawing increasing interest in the past years in structural health monitoring. This trend is particularly attributed to the attractive features of wireless sensor nodes in terms of both cost and labor as compared to cable-based systems. When wireless sensing technologies were introduced to the field of structural health monitoring, research focused primarily on power efficiency and wireless communication reliability. Various types of embedded software are proposed that execute basic functions within the nodes in an attempt to reduce the consumption of the inherently limited resources and to optimize their functionalities. Most software embedded into wireless sensor nodes is used to perform some basic local data processing and data analysis tasks. In previous review papers, the accumulated experience of the engineering community gained from the use of wireless sensor nodes in structural health monitoring is summarized, while focusing on hardware and technical specifications. This paper, by contrast, is intended to serve as a comparative review of state-of-the-art wireless sensor nodes with particular emphasis on the embedded computing capabilities and the suitability of nodes to autonomously solve complex monitoring problems in a decentralized manner.
