  1. Random Thoughts on MobiCom 2004

  2. Conference Facts • 326 submissions • 88 selected for discussion • TPC meeting: 26 selected on final program • 9 sessions, single-track • Acceptance ratio: ~8% • 65% are student papers • One Panel • Wireless Mesh Network

  3. Workshop Facts • 5 Workshops • DIAL M-POMC: Foundations of Mobile Computing • VANET: Vehicular Ad Hoc Network (1st) • WiSe: Wireless Security (3rd) • WMash: Wireless Mobile Applications and Services on WLAN Hotspots (2nd) • MobiWac: Mobility Management and Wireless Access (2nd)

  4. Topics by Session • Service infrastructure and network management • Experimental testbeds and data measurement • Algorithms for multihop networks (2) • Ad hoc networks • Sensor networks • Medium access control • Fairness and load balancing • Localization

  5. Topics by Network Technology • Mobile Computing Related (2) • Best paper • IEEE 802.11 (11) • One about wireless mesh • Sensor Network (4) • Multihop / Ad hoc / Generic Wireless Network (7) • One about wireless backhaul • WWAN / Cellular System (2)

  6. Topics by Contribution • Real System (5) • 2,2,1 • Modeling / Optimization / Measurement (5) • 1,3,1 • Novel Idea / Algorithm / New Direction (11) • Algorithm (4) • Protocol (7) • New directions: multi-radio, channel hopping • Borrow ideas from other fields (6) • Robotics (2) • Graph theory (4)

  7. Topics by Performance Evaluation • By Experiment / Prototype System (9) • Best paper • By Simulation Only (17)

  8. 1. Mobile Computing • Virtual desktop computing (best paper) • Code management/collection for resource limited mobile devices

  9. 2. IEEE 802.11 WLAN • Fault diagnosis and detection of unauthorized access point • Measurement and modeling of large-scale campus WLAN (2) • Routing in multi-radio multi-hop WLAN (wireless mesh) • Multi-user diversity and rate adaptation • Improving capacity via channel hopping • Battery-state aware MAC • Localization (2) • Local balancing via association control • Modeling of channel access protocols

  10. 3. Sensor Network • Localization • Power Conservation vs Quality of Surveillance • K-coverage • Initial deployment

  11. 4. Multihop / Ad hoc Network • Optimization of bounded flooding (in sensor network?) • Network deformation • Multicast routing • Topology control • Denial of Service • TCP over Ad hoc • Fairness in multihop backhaul network

  12. 5. WWAN and Cellular System • Performance optimization of WWAN system • Measurement study • Load balancing in multi-cell system • Packet-level scheduling • Call-level site selection • System level load balancing

  13. Summary • Novelty is KEY. • Research on building prototype systems or measurement. • Very appealing • A lot of work but doable! • MobiCom becomes more and more theoretical. • But novel ideas/protocols will survive!

  14. Summary • 802.11 is still an active area. • Most underlying systems are assumed to be 802.11 based • Several cross-layer papers (4). • Topics in multihop/ad hoc networks are diverse. • Not too many sensor network papers. • Other sensor networking conferences? • Not many security papers.
