Cover page Title: Distributed Data Processing Architectures for Structural Monitoring Systems Implemented on Wireless Sensor Networks for Proceedings of the Fourth European Workshop on Structural Health Monitoring

Over the past decade, a variety of information technologies have emerged from the computer science and electrical engineering fields that are transforming how we monitor and manage complex civil infrastructure systems. The end result are safer structures that are easier and more economical to manage over their operational lives. Foremost among the emerging new information technologies are wireless sensors. Wireless sensors are low-cost data acquisition nodes that integrate communication and computing functionality with a sensor. Low-cost structural monitoring systems defined by high nodal densities can be designed using wireless sensors. To offer a scalable approach to management of the large data sets possible in wireless monitoring systems, in-network computing by the wireless sensor network is a powerful approach to automation of interrogation of structural response data for signs of structural distress. This paper will present the authors' experiences with the research and development of wireless sensors designed explicitly for structural health monitoring of civil engineering structures.
