Abstract

According to one embodiment of the invention, a system for monitoring a structure includes a plurality of sensor modules coupled to the structure. Each sensor module includes a sensor operable to sense a characteristic of the structure and a communication device coupled to the sensor. The communication device is operable to receive a signal from the sensor representative of the sensed characteristic and to transmit data representative of the sensed characteristic to one or more neighboring communication devices. The system further includes a central repository operable to receive, from one of the communication devices, the data representative of each sensed characteristic.
