  1. 15-441 Computer Networking Lecture 5 – testbeds and simulation

  2. Readings • [G.1] On the accuracy of manet simulators. David Cavin, Yoav Sasson, and André Schiper, Workshop on Principles of Mobile Computing (POMC'02), pages 38-43. ACM, October 2002. • [G.4] Using Emulation to Understand and Improve Wireless Networks and Applications, Glenn Judd and Peter Steenkiste, Proceedings of NSDI 2005 • [H.3] "Overview of the ORBIT Radio Grid Testbed for Evaluation of Next-Generation Wireless Network Protocols," D. Raychaudhuri, I. Seskar, M. Ott, S. Ganu, K. Ramachandran, H. Kremo, R. Siracusa, H. Liu and M. Singh, To appear at the Wireless Communications and Networking Conference (WCNC'05) March 2005.

  3. Optional • [G.2] Experimental evaluation of wireless simulation assumptions. David Kotz and Calvin Newport and Robert S. Gray and Jason Liu and Yougu Yuan and Chip Elliott. Technical Report TR2004-507, Dept. of Computer Science, Dartmouth College, June, 2004. • 7 axioms of different errors that wireless simulators make • 0: The world is flat. • 1: A radio’s transmission area is circular. • 2: All radios have equal range. • 3: If I can hear you, you can hear me (symmetry). • 4: If I can hear you at all, I can hear you perfectly. • 5: Signal strength is a simple function of distance. • 6: Each packet is transmitted at the same bit rate. • [H.4] Design Considerations for a Multi-hop Wireless Network Testbed, Pradipta De, Ashish Raniwala, Srikant Sharma, and Tzi-cker Chiueh • Good overview/summary of different testbeds and their properties

  4. Optional • [H.1] "A Large-scale Testbed for Reproducible Ad hoc Protocol Evaluations", H. Lundgren, D. Lundberg, J. Nielsen, E. Nordström, C. Tschudin, WCNC 2002. • APE system – relies on careful choreography of users • [H.2] Lowering the Barrier to Wireless and Mobile Experimentation, Brian White, Jay Lepreau, Shashi Guruprasad, ACM HotNets-I, October 2002. • Emulab converted to wireless • Nice emulab interface but simulation is specific to deployment • [H.3] "Overview of the ORBIT Radio Grid Testbed for Evaluation of Next-Generation Wireless Network Protocols," D. Raychaudhuri, I. Seskar, M. Ott, S. Ganu, K. Ramachandran, H. Kremo, R. Siracusa, H. Liu and M. Singh, To appear at the Wireless Communications and Networking Conference (WCNC'05) March 2005. • Nice indoor, dense, mesh deployment testbed • [H.5] "Wireless Link SNR Mapping Onto an Indoor Testbed," J. Lei, R. Yates, L. Greenstein and H. Liu, Submitted to IEEE Tridentcom 2005 • [G.3] WhyNet description (focus on hybrid testbed methodology), available at http://chenyen.cs.ucla.edu/projects/whynet/ • Not much here – but one of the well known planned testbeds
