Abstract: Wireless structural health monitoring research
has drawn great attention in recent years from various
research groups. While sensor network approach is
a feasible solution for structural health monitoring, the
design of wireless sensor networks presents a number
of challenges, such as adaptability and the limited communication
bandwidth. To address these challenges, we
explore the mobile agent approach to enhance the flexibility
and reduce raw data transmission in wireless
structural health monitoring sensor networks. An integrated
wireless sensor network consisting of a mobile
agent-based network middleware and distributed high
computational power sensor nodes is developed. These
embedded computer-based high computational power
sensor nodes include Linux operating system, integrate
with open source numerical libraries, and connect to multimodality
sensors to support both active and passive
sensing. The mobile agent middleware is built on a mobile
agent system called Mobile-C. The mobile agent middleware
allows a sensor network moving computational
programs to the data source. With mobile agent middleware,
a sensor network is able to adopt newly developed
diagnosis algorithms and make adjustment in response to
operational or task changes. The presented mobile agent
