Abstract

A sensor network for monitoring of a pipeline comprises a sensor disposed for monitoring of a pipeline, the sensor capable of acquiring data related to the pipeline and communicating sensor data; a first remote sensor interface (RSI) comprising a data communications device capable of receiving the sensor data communicated from the sensor, and transmitting data relating to the received sensor data; and a data communications device capable of receiving the data transmitted by the first RSI and transmitting data related to the sensor data directly or indirectly to a network external to the sensor network. The sensor network comprises a common designation network.
