Dr. Maneesha V. Ramesh, Nibi K. V., Kurup, A., R. Mohan, Aiswarya, A., Arsha, A., and Sarang, P. R., “Water Quality Monitoring and Waste Management using IoT”, in 2017 IEEE Global Humanitarian Technology Conference (GHTC), 2017.[Abstract]


Poor water quality in Pettipalam Colony in Thalassery, Kannur District, Kerala is the source of many health issues among the colony residents. Soil and water contamination due to the accumulation of waste is another serious issue that adversely affects the health of the inhabitants in the area. There is a compelling need for the village inhabitants to appropriately monitor the water bodies and take suitable measures to dispose of the waste in the area. Over 2 acres of land is inhabited by people in Pettipalam Colony at Thalassery. Their colony ground was used as a municipal waste dump yard until 2014. Presently, also, the colony residents use the area for waste disposal and open defecation, thus contaminating the land and soil with plastic, organic, and chemical pollutants, etc. These contaminants affect the ground water and get washed into the water bodies when it rains, thus polluting the water resources. Techniques such as Bio-remediation (use of microorganisms to remove or neutralize pollutants) and vermi-composting, which triggers growth of plants that absorb the contaminants, can be introduced to address the issue of reducing the level of contaminants in the soil. But these solutions require proper identification of the contaminants. An extensive sensor system, which can monitor the contaminants in the soil as well as the water bodies, is essential. This project aims to design and develop an IoT based system that can sense the environmental parameters and effectively deliver information on the level of contamination and the quality of the water. Sensors to detect the hydrocarbons, chemical and metal content in the soil can be integrated into a soil probe for monitoring the soil contamination. And sensors for detecting pH, conductivity, dissolved oxygen, turbidity, etc. can be used for monitoring the water quality in the rivers, ponds, etc. in the site of interest. The design, development and implementation of an IoT based system will help the authorities take the necessary steps to perform proper waste management of the affected area. We anticipate that monitoring the suitable parameters will help to impact land restoration initiatives in many areas of India.

P. Rekha, P. Venkat Rangan, Dr. Maneesha V. Ramesh, and Nibi K. V., “High Yield Groundnut Agronomy: An IoT Based Precision Farming Framework”, in 2017 IEEE Global Humanitarian Technology Conference (GHTC), 2017.[Abstract]


Agriculture is one of the main needs for human to survive. Agriculture has to tackle many problems like changing climate, water shortage, changing soil quality, etc. Due to the increasing demand for cereals and other crops for daily usage by the consumers there is a need for smarter implementation of irrigation and also develop farming methods that alter the basic eco systems and is less harmful to other creatures. India is one of highest crop producing countries all over the world. At the same time, India is facing the challenge of farmers committing suicide because of crop failure and debt. Most of the land in India is still being used for agriculture purposes. Still there exists several places that uses very primitive methods for irrigation, fertilization etc. This leads to the reduction in the crop yield and eventually less income for the farmers. This paper discusses the design and development of an IoT framework that helps farmers to improvise their methods of farming and also make the best use of their land for a better yield and income. The major goal of this IoT framework is to sense agriculture characteristics and advice farmers to properly grow and treat the crops. The system deploys a group of wireless sensor networks nodes deployed in the field for sensing agricultural parameters and the RF communication of WSN node is used to transmit the measured data to base station. Base station is connected to a decision support system. Based on the sensed parameters and the optimum values, the decision support system will generate an appropriate message for farmers. By using the collected data from the sensors, the proposed system will provide suggestions about the monitoring crop such as irrigation timings, directions for optimum usage of fertilizers etc. in accordance to the farmers' lands. An android application has been designed to deliver the messages to farmers in their regional language. The android app also gives information regarding the weather forecast and precaution to be taken based on the weather forecast.

Nibi K. V., K.A. Unnikrishn Menon, and Preeja Pradeep, “Underground Tunnel Detection Across Border Areas (in Press)”, in 1st International Conference on Power, Circuit and Information Technologies (ICPCIT-2015), Bangalore, India, 2015.[Abstract]


Tunnels are considered as the oldest method of passageway. Underground tunnels are popular from olden eras for connecting places, travelling, and aid for various surface threats. They are also used for illegal activities like smuggling of unlicensed drugs, weapons, currency, gold, explosives, and even human trafficking is being done through these tunnels. These immoral activities are concentrated in national border areas in order to escape from the border security measures. Hence the detection processes of such tunnels in the national security border areas are necessary in order to protect our homeland security systems. The geology plays an important role in the detection of the underground tunnel system procedures. There is no perfect system for the tunnel detection and localization and even today the tunnels revealed in coincidence. The basic principle to find the hollow space (tunnel) is, by sending an ultrasonic frequency signal into the ground, and study the reflected beam from the tunnel or the hollow space. By analyzing the reflected signal characteristics, preliminary detection of a tunnel/void is possible. Basic idea of the detection is to perform the range estimation algorithm (REA) by pulse echo method. From these, we can estimate the depth of the tunnel. The characteristics of the signal at the soil-tunnel (air) reflection interface are to be investigated. © Springer India 2016.

J. Mary Varghese, Sethuraman Rao, Nibi K. V., and Varghese, V. T., “A Survey of the State of the Art in ZigBee”, International journal on cybernetics and informatics(IJCI), vol. 4, no. 2, 2015.[Abstract]


ZigBee is one of the most widely used wireless communication technologies. ZigBee is being widely used for sensor communications and many other research fields. Why consider ZigBee? Because it is cheap and has better compatibility when compared to other communication technologies. We have given a detailed description on comparison between all the available technologies. In this paper, we have discussed some basic concepts about ZigBee and its security aspects in networking. We have also listed out the major manufacturers who are into the production of the transceivers for ZigBee.
