1 CPSC 641 Course Project Ideas Carey Williamson Department of Computer Science University of Calgary

2 PROJECT OVERVIEW H A “typical” course project might involve: –design/build/obtain appropriate testbed, environment, or platform for your project –extend/customize as needed –obtain relevant data/measurements needed –design suitable experiment: clear goal, identify factors, levels, performance metrics –obtain and describe (new/interesting) results

3 Examples of Recent Projects H Benchmarking dynamic Web content generation H Web browsing using wireless PDAs Web browsing using wireless PDAs H Traffic classification using machine learning H Temporal locality in media workloads H WWW2007 Web workload characterization H Benchmarking modern Web browsers Benchmarking modern Web browsers H Probabilistic key distribution in WSNs H Measurements and analysis of IP-TV

4 Experimental Equipment H Wireless laptops (6), PDAs (4), and APs (4) H Wireless network analyzers (3) H Wireless video cameras (3) H Wireless sensor motes (12) H Rack-mounted clients, servers, and proxies H WiMAX modem (1) H EV-DO air card (1) H iPod touch with WiFi (3)

5 Some Available Simulators H ns-2 network simulator (TCP packet level) H OpNet simulator H Web proxy caching simulator H ATM-TN simulator (ATM cell-level) H IP-TN simulator (U of C) H IP-TNE network emulator (U of C) H Peer-assisted streaming H EV-DO cellular network scheduling

6 Some Useful Software Tools H Synthetic Web proxy workload generation H Web client traffic model (mosaic, 1995) H LRD traffic analysis (R/S, V-T, AC, etc) H GUI for traffic modeling/analysis (synTraff) H Wavelet-based traffic model (MWM) H Synthetic MPEG video trace generation H GISMO (Generator for Internet Streaming Media Objects)
