A mobile-agent-based wireless sensing network for structural monitoring applications

Abstract

A new wireless sensing network paradigm is presented for structural monitoring applications. In this approach, both power and data interrogation commands are conveyed via a mobile agent that is sent to sensor nodes to perform intended interrogations, which can alleviate several limitations of the traditional sensing networks. Furthermore, the mobile agent provides computational power to make near real-time assessments on the structural conditions. This paper will discuss such prototype systems, which are used to interrogate impedance-based sensors for structural health monitoring applications. Our wireless sensor node is specifically designed to accept various energy sources, including wireless energy transmission, and to be wirelessly triggered on an as-needed basis by the mobile agent or other sensor nodes. The capabilities of this proposed sensing network paradigm are demonstrated in the laboratory and the field.

Evaluation of Multi-agent Architecture for Structural Damage Detection and Location

“…Also, the integration of each agent into SHM is explained. [29] Proposes a mobile agent to be used in SHM. Every sensor is checked periodically by the agent.…”

Improving Performance and Versatility of Systems Based on Single-Frequency DFT Detectors Such as AD5933

“…It usually involves a piezoelectric transducer tightly coupled mechanically with some component of a complex engineering structure such as a bridge, naval vessel, airplane, and others [6][7][8][9]. The component can be a metal or a concrete beam [6,9,10] or bolted joints [7,11,12], etc. Mechanical resonances of the structure can be excited and observed by measuring complex impedance of the transducer.…”

Estado del arte en monitorización de salud estructural: Un enfoque basado en agentes inteligentes

“…Se especifican también, los diferentes niveles organizacionales que se requieren para realizar una monitorización con esta arquitectura los cuales son los niveles de monitorización de datos, interpretación de los mismos, diagnóstico de daños y el nivel de información que es el único que entra en contacto con el usuario. taylor, et al [56], plantean el uso de un agente móvil para mejorar el rendimiento de una red de sensores de monitorización de salud estructural. el agente móvil está encargado de revisar periódicamente los datos de los sensores y posee la capacidad computacional para realizar juicios sobre la condición de la estructura acerca de su estado y acerca de sus fallas.…”
