MANET Simulation Studies: Reversing the Incredibles
Colorado School of Mines
4/3/2007
3:30pm-4:30pm

A mobile ad hoc network (MANET) is defined by mobile network nodes, no fixed infrastructure, multi-hop communication, and unreliable wireless links. In the MANET research community, simulation is the main tool used to study these dynamic networks. To determine the state of MANET simulation studies, we surveyed the 2000-2005 proceedings of the ACM International Symposium on Mobile Ad Hoc Networking and Computing (MobiHoc). From our survey, we found significant shortfalls in the credibility of presented simulation results.

A simulation scenario must be properly constructed to be effective in evaluating the performance of a MANET routing protocol. For example, a poorly defined routing protocol might appear successful in a scenario with a low average hop count because little routing is needed. Of course, many standards are needed to establish a rigorous evaluation procedure for MANET simulation research, e.g., standards are needed for simulation scenarios, random number generation, and results analysis.

In this talk, I will propose and explore two standard metrics that researchers should consider to ensure long routes are available and used in the evaluation of a MANET routing protocol. I will also discuss tools that my students and I have developed to assist MANET researchers in improving the credibility of MANET simulation-based studies. Lastly, I will briefly present past successes, current research challenges, and future directions of my research group.

Tracy Camp received her PhD from the College of William and Mary in 1993, and is currently an Associate Professor of Computer Science at the Colorado School of Mines. She is the Founder and Director of the Toilers, an active research group in self-organizing networks. Dr. Camp has received 12 grants from NSF, including a CAREER award in 1997. She has published over 50 refereed articles and 9 invited articles; as of August 2006, her articles have been cited over 1300 times (per Google Scholar). Dr. Camp recently returned from New Zealand, where she was a Fulbright Scholar. She is currently a member of the Ad Hoc Networks Journal and Pervasive and Mobile Computing Journal editorial boards, the elected Treasurer of ACM's Special Interest Group on Mobile Computing (SIGMOBILE), and a member of ACM's Committee on Women in Computing. Dr. Camp was recently invited to be an ACM Distinguished Lecturer (August 2006), awarded IEEE Senior Member status (July 2006), and selected as an ACM Distinguished Scientist (October 2006).
