- COMSNETS 2019Bengaluru, India, 2019Invited Paper: Thoreau: A fully-buried wireless underground sensor network in an urban environment", Xufeng Zhang, Arseniy Andreyev, Colleen Zumpf, M. Cristina Negri, Supratik Guha, and Monisha GhoshThis 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. Index Terms—wireless sensor network, underground, internet of things, urban environment, soil sensing. Read More

Balhara, R. C. Ponduru, H. Sharma, S. Chary, G.B. Subramanyam, S. Randhawa, T. Dutta, H. P. Gupta, A. Gupta, A. Haldar, A. Sarkar, I. Khan, S. Guha, IEEE Sensors Conference 2018, New Delhi, India, 2018The world faces a grave water risk that affects all aspects of human life and ecology with implications for food security, energy production, industrial activity and human health. In this study, we use mobile (moving) sensors to spatially and temporally map river water quality based on in-situ data gathered in some of India’s major rivers. Data visualizations generated are intended to pinpoint sources of pollution, ensure regulatory compliance and examine health of the water body. We show that such cyber physical sensing techniques can be a powerful and more practical (or cost-effective) way to dynamically monitor, predict and regulate the quality of large bodies of water.

- SPIE, 2018Berlin, Germany, 2018"BLUEWATER EYE: Using satellite as a low cost water pollution sensor: Analytics for deriving long term pollution insights based on mapping water turbidity”, S. Randhawa, R. Guruprasad, S. Balivada, P. Hirani, S. Guha, SPIE Remote Sensing Conference, Berlin, Germany, 2018.We leverage geo-spatial data analytics in combination with cloud based, real-time in-situ sensing, that is capable of mapping changes in water turbidity of a water resource. Spatio-temporal pollution insights are derived and represented via color-based heatmaps and matrices that are overlaid on Google maps and facilitate visualization and identification of pollution hotspots.

- IEEE Workshop, WCNEE 2017Atlanta, GA, USA, 2017"Thoreau: A subterranean wireless sensing network for agriculture and the environment", Xufeng Zhang, Arseniy Andreyev, Colleen Zumpf, M. Cristina Negri, Supratik Guha, and Monisha Ghosh, 1st IEEE Workshop on Wireless Communications and Networking in Extreme Environments (WCNEE 2017), Atlanta, GA, USA, 2017This paper presents the deployment of a working Wireless Underground Sensor Network (WUSN) on a university campus using existing wireless networking technology at 902 MHz. This is the first full system of its kind that is operational over a long time, with the data being gathered available in real time on an open website. Design details of the WUSN are described, including the network architecture, sensor nodes, user interface and power management techniques. Initial results obtained from the sensor network are provided and analyzed, showing information regarding soil properties and their influence on the performance of the wireless transmission. Read More
