13. CprE 592 -- D.Q.13 Summary Novelty is KEY. Research on building prototype systems or measurement. Very appealing A lot of work but doable! MobiCom becomes more and more theoretical. But novel ideas/protocols will survive!

14. CprE 592 -- D.Q.14 Summary 802.11 is still an active area. Most underlying systems are assumed to be 802.11 based Several cross-layer papers (4). Topics in multihop/ad hoc networks are diverse. Not too many sensor network papers. Other sensor networking conferences? Not many security papers.
