Panel Information

Panel 1 - Using collision-free scheduling: dream or reality?

[audio] [video]

There has been significant recent work on designing optimal scheduling solutions (e.g. TDMA-based). But there are fundamental questions about the implementability of such approaches: how to compute them in polynomial time, how to implement them in a decentralized fashion with low overhead, and yet stay near-optimal.

Panel 2 - Is random access fundamentally inefficient?

[audio] [video]

A number of recent studies have raised questions about the ability of random access to achieve fair and efficient performance especially in multi-hop scenarios. It is important to access whether these issues are fundamental or if they are artifacts of the way random access is implemented and used, and of the current practice of keeping higher layers unaware of interference.

Panel 3 -  What constitutes a useful experimental result?

[audio] [video]

Good experimental work can raise new questions and play an important role in validating or invalidating assumptions of and results from theoretical work. At the same time, experimental research faces the criticism of being driven too narrowly by current hardware limitations and market realities.

Panel 4 -  What constitutes a useful theory result?


The field has seen a number of theoretical findings varying from asymptotic results, some with potentially large hidden constants, to meticulous calculations that model almost all the details of specific protocols. What kinds of results in this spectrum are useful in understanding practical issues and then designing real protocols to address them?

Panel 5 - Cooperation instead of contention!

[audio] [video]

From physical layer cooperation and coding to the use of multi-channel radios, recent research has suggested exploiting simultaneous transmissions instead of treating them as interference.

Panel 6 - Medium access in new contexts: reinventing the wheel?

[audio] [video]

A number of new kinds of wireless systems are emerging, for example underwater networks, cognitive radio networks, embedded networks, vehicular networks, and delay tolerant networks. Do these systems require fundamentally new ways to manage interference?
