While I was trained as a Nuclear Fusion Scientist and spent nearly two decades working on Nuclear Fusion in USA and India, I moved to Dhirubhai Ambani Institute of ICT(DA-IICT), Gandhinagar in Gujarat in summer of 2002 as Professor to enlarge my area of work. Considering the focus areas of DA-IICT, I felt that I could work on Robotics to help manage remote control requirements of Nuclear Fusion Reactors. As I was going through literature on Robotics, I started to see the scope of group of Robots linked by communication and working in a cooperative manner. From here I stumbled upon the concept of Wireless Sensor Network(WSN) or Sensor Network.
