  1. Business models & killer applications forContext-based & P2P Services WMCS’06 Panel Chen-Nee Chuah Electrical & Computer Engineering University of California, Davis http://www.ece.ucdavis.edu/~chuah

  2. Mobile Applications • Mobile Messaging • SMS • Video e-mail • Unified messaging • Information/Entertainment • News, sports • Financial • Directory services • Yellow pages • Travel/Location • Traffic information • Navigation services • Location services • Travel schedule updates • On-Demand Access • On-demand video • Content distribution • Gaming • General Messaging • IP-telephony • Videoconferencing • Webcasting • Internet Access • Web browsing • Portals • WAP

  3. Technological Trend • GPS/Localization techniques • Multiple interface: cellular, wifi, bluetooth/zigbee • Output: display technology, audio • Advanced input capabilities: keyboard, audio, touch-screen, etc. • Power save mode

  4. What do we mean by Context ? • Usage context: topic, interest, etc. • User attributes • Professions, age, gender, etc. • Spatial/location • E.g., advertising local restaurants • Temporal • Time of day, specific holidays (Father’s day, etc)

  5. Location-Aware Services • Limitations with GPS • Doesn’t work in downtown SF! Relatively expensive! • Other low-cost solutions: landmark-based • Intel PlaceLab software (http://www.placelab.org/) • Detecting 802.11 APs with known locations and triangulate • Wigle.net (http://wigle.net/) • Database of discovered wifi w/ GPS locations • Challenges • Privacy issues: users do not want to be tracked! • Remote query vs. client-based localization

  6. Location-aware Services: Opportunities • Abundant wifi APs! • Landmark broadcast by local businesses? • Provide location info to users while advertising services?

  7. Revisit Wireless Connectivity • Infrastructure-based connectivity • Cellular: wide-area, continuous coverage, low bit-rate • 802.11 a/b/g (wifi): intermittent, high bit-rate connectivity when you’re close to a hotspot • Peer-to-peer connectivity • Ad hoc 802.11 & Bluetooth/zigbee: high bit-rate in close vicinity with peers Questions: • How do we leverage P2P connectivity? • What are the roles of personal area networks (PANs)?

  8. Leveraging Intermittent Connectivity Substitution vs. alternative platforms • Wifi hotspots as alternative • Fill in the coverage gap for cellular network • Increase user bandwidth, e.g., if clients could use multiple interface simultaneously Time: exposure vs. action • Delay-tolerant networking (http://www.dtnrg.org) • Continuous end-to-end connectivity is not guaranteed • Data bundles are forwarded using intermittent connectivity but transparent to users, e.g, • Offline emails that are automatically forwarded using intermittent connectivity through intelligent middleware

  9. Role of P2P Connections • Trends: • PDAs, cell phones w/ bluetooth interface • Inter-vehicle, vehicle-to-roadside communications via DSRC channels • Opportunities: • Client nodes as data relay to ‘extend’ wireless coverage • Client nodes as data sources, e.g., P2P file sharing, ambient logging • Cooperative downloading to increase bit rate • Collaborative queries for services, e.g., VANET for traffic status, free parking space information

  10. Example Research Projects • Intel/Cambridge Haggle Project • ‘Pocket Switching’ via multi-hop P2P links • http://www.haggleproject.org/ • Berkeley Tier Project • Technology and infrastructure for emerging regions • http://tier.cs.berkeley.edu/ • Waterloo’s Mindstream Project • Opportunistic communications • http://mindstream.watsmore.net/ • UC Davis’s VMesh/VGrid Project • Distributed sensing and data computation • http://www.ece.ucdavis.edu/rubinet/vmesh.html

  11. P2P Services: Challenges • Incentives • Security & privacy • Killer applications? • What are the roles of the players? • Network operators vs. content provider vs. customers • Business models? • Content providers use P2P for efficient data distribution? • Wireless providers act as marketing intermediary and provide e-bay type platform for wireless peers/clients to trade content? • Content generation & marketing by peers (provider is out of the picture)?

  12. Questions? Discussions? • Acknowledgment • Hemant Bhargava, UC Davis
