Chayan Sarkar




I am a Scientist at the TCS Research & Innovation and currently working at the Kolkata lab. I am part of the Embedded Systems and Robotics group and my main research focus is multi-robot systems, human-robot interaction, and Internet-of-Things. Before that I worked briefly as a researcher at SICS Swedish ICT in Sweden. I got my bachelor’s and master’s degree from Jadavpur University in 2009 and IIT Bombay in 2011, respectively. I completed my PhD studies at the Delft University of Technology in Netherlands in 2016.

Efficient wireless communication for IoT

A popular technique to reduce overall data traffic in a WSN is to keep only a subset of nodes active at any point of time. Data for the sleeping nodes can be reproduced using the data from the active nodes. This reproduction utilizes the inherent spatio-temporal correlation amongst the nodes. Although correlation based sensor data estimation can reduce the overall data traffic significantly, without a complementary routing mechanism, the energy efficiency can be diminished significantly. Also special, routing mechanism is required for energy harvested network and real-time network.

Code & Demo

Most good programmers do programming not because they expect to get paid or get adulation by the public,
but because it is fun to program. - Linus Torvalds
