CIAN students at Columbia University, from the WiMNet lab of Dr. Gil Zussman, including Raphael Norwitz, Savvas Petridis, Craig Gutterman, and Varun Gupta recently took home the 2nd place prize (out of about 100 demonstrations) for the New York City Media Lab Summit.
In a joint project of the WiMNet Lab and Alcatel Lucent Bell Labs we have been developing the AMuSe (Adaptive Multicast Services) system. AMuSe combines methods for collecting accurate feedback information with low overhead and for network adaptation (e.g., transmission rate) based on this feedback. Specifically, the system includes a scheme for dynamic selection of a subset of the multicast receivers as feedback nodes, which periodically send information, such as channel quality or received packet statistics, to the multicast sender. Moreover, it includes schemes for dynamic rate adaptation based on the collected feedback.
This system was implemented in the ORBIT testbed to evaluate its performance in large groups with 150 to 200 receivers.
CIAN students Raphael Norwitz and Savvas Petridis are also recent recipients of the CIAN Undergraduate Research Fellowship. Learn more and apply.
