“Now Cliched” Application Spaces Are Relevant
• Tactical Military
– > $10B JTRS/TCA Market for DoD Network-Centric Warfare (NCW)
• Emergency Services (Police, Fire, Rescue, Etc.)
– Market (post-9/11) will materialize; Ex.: PacketHop demo in Bay Area
• Disaster Relief / Humanitarian Operations / News Reporting
– WLANs augmented by commercial SATCOM (Inmarsat/Iridium)
• Space / Planetary Exploration
– Presidential manned space initiative
• Industrial Controls
– Factory automation, maintenance, safety, and security
• Inter/Intra Home Mesh Networking
– Implemented by Rooftop (among others) in the late 90s
No Application Has Achieved Mass Market Status, Yet…

Inter/Intra Home Mesh Networking
• Intra is now happening for nomadic users (because someone can make $)
– Fixed hotspots - coffee shops, hotels, airports, etc.
– Mobile hotspots - Trains, planes, buses, and ships
• Can do hotspots at home, but if not nomadic, wires are better
– Data rate, reliability, security, etc.
• How might the mass market develop for Inter/Intra develop?
– The “Cringely” example: School fund raiser creates a useful mesh density
– Up front cost for infrastructure but then free “dial-up”-like performance
• Technological/sociological roadblocks still exist
– Security
– Resource sharing (fairness)
– Legal/Law enforcement
• Will regulatory/competitive forces prevent development of mass market?
– Does sufficient unlicensed spectrum exist to support?
 Do dynamic spectrum sharing approaches address this challenge?
– This approach will be resisted by the current service providers
 Not a problem if there is no incumbent/infrastructure, which is the case for many areas

Mobile, Wireless (Kids) Gaming
• Hand Held Gaming Device
– Affordable ($100s)
– Hardened for use by kids
– Standalone as well as able to attach to infrastructure (hot spots, etc.)

• Lower Bar for Success for (Kids) Gaming
– Sufficient unlicensed spectrum exists (No .ppt or web pages files)
– No incumbent to overcome; a new (but adjacent) market for all players
– “Real” security is not an issue (maybe hacking is part of the game?)
• A Commercial Market (PS2/XBox-like) Would Lower Cost to $100s
– DoD wants this Now for every dismount but can’t afford it (batteries)
– Other applications and markets would develop

Stepping on My Technical Soapbox…
• Default Media Access Control (MAC) approaches (e.g. 802.11x) are
inefficient when used in Mesh/MANET contexts vice the AP/cellular
context for which they were designed
– Hidden terminal/exposed node; QoS/congestion; etc.
• So why does everyone use it? Its cheap!
– The MAC is embedded in the cheap radio and can’t be modified very easily
• The MAC challenge has received insufficient attention in comparison to
the PHY and routing challenges
– Is it a EE/PHY/Radio problem or is it a CS/NET/Router problem
– An integrated/cross-layer approach is preferred
• The community will have to move away from stochastic (e.g. RCDA)
approaches to deterministic approaches (e.g. TDMA) for QoS
– Timing is now free from GPS
– Needs attention in standards bodies which traditionally are routing focused
