Abstract

This paper presents the development and performance study of a two-level wireless sensor network (WSN) for structural health monitoring (SHM). The lower-level network adopts low-power ZigBee protocol whereas the higher-level network employs high speed WiFi communication for long distance data transmission. To promote distributed data processing and damage diagnosis, the higher-level sensor nodes are designed to possess high computational capabilities. A reliable data transmission mechanism is implemented in the lower-level ZigBee network. To reduce the power consumption and quickly respond to extreme events, an eventdriven monitoring approach is proposed. The impact of the coexistence of ZigBee and WiFi on the system's performance is also studied. Copyright © 2009 by ASME.
