[4/24] Lecture notes for today's class have been posted on the "schedule and notes" page. In the first part of today's class, we'll cover the two papers "Wireless Link-Level Measurement" and "ExOR: Extremely Opportunistic Routing"; we'll spend the second part of the class to hold a "Q&A" session on your final essay (so please come to the class today if you can!). We'll finish up the paper "XOR in the Air" in next week's class. We'll spend the remaining time in next week's class to have a "round-table" discussion on Future Internet Architecture issues. Please think about what fundamental problems/issues you think that the current Internet suffers, and if you were asked to design for the Future Internet Architecture, what mechanisms and architectural components would you like to see incorporated, or "designed-in"? As a means to inspire you, please read the required (and optional) papers on the (updated) reading list; on the other hand, we will _not_ go over these papers in details (as in other classes) next week.
