Invited Paper: Thoreau: A fully-buried wireless underground sensor network in an urban environment

This paper describes the design and deployment of a functional Wireless Underground Sensor Network (WUSN) on a university campus. This is an unique system that is operational over a large area and over a long period of time, providing real time monitoring of the environment with the data being curated and displayed on an open website. The system details, including the architecture, node design, user interface, and deployment are provided. Initial measurement results are analyzed to show the functionality and performance of the system.
