1. Research Experience W.Lilakiatsakun

2. Before Get started Must have a Goal –PhD. –Academic Position –Etc For me, it was to finish PhD. ASAP.

3. Started From Scratch Prof. Aruna told “ Power saving for mobile devices is an interesting topic” Then, I went to 2 important Websites –http://ieeexplore.ieee.org/Xplore/guesthome.jsphttp://ieeexplore.ieee.org/Xplore/guesthome.jsp –http://portal.acm.org/dl.cfmhttp://portal.acm.org/dl.cfm

4. Get Keyword Keyword –Power /Energy saving –Mobile devices –Wireless –And etc

5. Surveying Read a lot of related papers and also improve the basic knowledge –Power/energy saving techniques –Wireless link characteristic –Wireless Protocol –TCP/IP Protocol –TCP for Wireless link

6. Finally I came out with an idea “Energy Saving Techniques on TCP over wireless Link” Next Problem is how to prove my idea

7. How to Prove Mathematics –Not easy for me Simulation –It is possible Experiment –Too difficult to control environment

8. Tools Simulation Tools –Network Simulator (NS2) Free / Open source and widely used in research community http://www.isi.edu/nsnam/ns/ http://www.isi.edu/nsnam/ns/ –OpNet /Licensed / not widely used Other tools –MATLAB –GNU plot /Microsoft EXCEL

9. To use NS2 you need to know Linux fundamentals TCL Script –To generate topology C++ –To create your plug in module for NS2 Shell Script –To do management tasks

10. Simulation Assumption Error Model –Random error –Correlated error (Two–state Markov Channel) Comparing your technique and the existing techniques

11. Simulation Results Your technique Vs others It would be shown as –Tables –Line/ Bar Graph

12. Research Interest TCP/IP Protocol design to improve energy efficiency Video Streaming on multi servers –Peer to Peer –CDN Distributed Network Management –Efficient management VoIP –Anti SPAM on VOIP –mobile devices to save energy
