Objective

The 1st IITM-IITB Communications Research Workshop was held in the Dept. of Electrical Engineering, Indian Institute of Technology - Madras, Chennai, from 3rd to 5th July 2006. The workshop consisted of talks on recent research by faculty and research scholars of both IITs, with an ultimate aim to identify 2-3 joint projects.

Participants from IIT-Bombay

Participants from IIT-Madras

Workshop Notes

  1. Overall, the participants opined that the IITM research group has a lot of expertise in the Physical and MAC layers, while the IITB research group had expertise in MAC, Network and Transport layers. Thus, it would be fruitful to leverage each other's expertise and work jointly on the L1-4 aspects on following projects:
    1. Sensor Networks - build a prototype
    2. 802.11 / 802.16 Simulator - develop a realistic simulator
    With the help of faculty members of both sides, a joint proposal on the above has been targeted by August 1st week.
