1. Medium Access in New Contexts: Are we Reinventing the Wheel? Mingyan Liu University of Michigan, Ann Arbor Mingyan Liu University of Michigan, Ann Arbor

2. It’s rarely exactly the same wheel  New contexts, new properties, new constraints  Multichannel systems  Underwater, acoustic communication  New PHY results ...  New insights -- what may be ignored in modeling and analysis  Verifying old wheel on new road  Valid  Sometimes necessary  New contexts, new properties, new constraints  Multichannel systems  Underwater, acoustic communication  New PHY results ...  New insights -- what may be ignored in modeling and analysis  Verifying old wheel on new road  Valid  Sometimes necessary

3. But…  Reinventing does not require new contexts  802.11  We are influenced by what we already know  Doing without knowing…  Organizing literature  Does the application define the problem?  Or is it the abstraction?  Reinventing does not require new contexts  802.11  We are influenced by what we already know  Doing without knowing…  Organizing literature  Does the application define the problem?  Or is it the abstraction?

4. Some thoughts  Better dialogue  Better understanding of PHY advances  Putting theoretical results into context  Some community based effort?  Better dialogue  Better understanding of PHY advances  Putting theoretical results into context  Some community based effort?
