CSOnet: A Metropolitan Scale Wireless Sensor-Actuator Network for Storm Water Management

This paper describes recent a metropolitan (citywide) scale deployment of a sensor-actuator network called CSOnet. CSOnet is a sensor-actuator network that monitors and controls the frequency of Combined-Sewer Overflow (CSO) events in municipal sewer systems. CSO events represent a major problem having a significant negative impact on public health This paper describes the hardware, middleware, and distributed control components being used by CSOnet. Wireless Sensor Actuator Networks or WSANs introduce a novel and important dimension to the paradigm of sensor-only networks. WSANs implement devices that are not only able to measure and detect events in the environment, but are also able to interact dynamically with it. WSANs are therefore examples of so-called Cyber-Physical Systems.
