Amrita Vishwa Vidyapeetham’s world-class research in wireless technologies was recognized yet again at a prestigious and recent International Conference.
 

Three research papers from the Amrita Centre for Wireless Networks and Applications were selected for presentation at SENSORCOMM 2010 – The Fourth International Conference on Sensor Technologies and Applications. SENSORCOMM covers topics related to theory and practice on wired and wireless networks and sensor networks.
 

The research papers were titled Integrating Geophone Network to Real-Time Wireless Sensor Network System for Landslide Detection; Real – Time Monitoring and Detection of Heart Attack Using Wireless Sensor Networks; and Wireless Smart Grid Design for Monitoring and Optimizing Electric Transmission in India.
 

Recent years has shown an increase in the occurrence of natural disasters, threatening human life and property. Early warning systems could help in reducing the impact of such disasters. Dr. Maneesha and her colleagues designed and deployed a real-time wireless sensor network for landslide detection, in one of the landslide prone areas in India.
 

Amrita researchers Abhishek T. K. and Dr. Maneesha V. Ramesh authored the paper Integrating Geophone Network to Real-Time Wireless Sensor Network System for Landslide Detection.
 

“The current system has a single axis geophone installed in it. This captures information from one direction,” stated Abhishek. “Our research work incorporates a three-axis geophone into the system so that information from three directions can be captured at a single time. The new design of nested geophone has been tested and validation is now being done in our lab.”
 

The second paper, Real – Time Monitoring and Detection of Heart Attack Using Wireless Sensor Networks, was penned by Kala John and Dr. Maneesha V. Ramesh.
 

“This paper talks about the design of a system used to monitor the cardiac system within the human body,” stated Kala. An M. Tech. student in Amrita’s Wireless Networks and Applications program, Kala further elaborated on the concept.
 

“The system collects ECG signals from the body through a mobile. A sensor will be kept inside the body of the patient. This will send signals to the mobile at regular intervals. The ECG analysis is done in the mobile and the reports will be sent to relatives and doctors.”
 

“The advantage of this system is that, wherever the patient goes, the doctor can keep an eye on the health condition of the patient,” she added.
 

The final paper, Wireless Smart Grid Design for Monitoring and Optimizing Electric Transmission in India, was co-authored by Arya Devi R. D. and Dr. Maneesha V. Ramesh.
 

Electricity losses in India during transmission and distribution are extremely high and vary between 30 to 45%. Wireless network based architecture was proposed in this paper, for monitoring and optimizing the electric transmission and distribution system in India. The system consists of multiple smart wireless transformer sensor nodes, smart controlling stations, smart transmission line sensor nodes, and smart wireless consumer sensor nodes. The proposed software module also incorporates different data aggregation algorithms needed for the different pathways of the electricity distribution system.
 

The implementation of this system can potentially help save a large amount of electricity.
 

Once again, researchers from Amrita Vishwa Vidyapeetham are creating solutions to help solve monumental problems of humanity.
