“Now Cliched” Application Spaces Are Relevant • Tactical Military – > $10 B JTRS/TCA Market for Do. D Network-Centric Warfare (NCW) • Emergency Services (Police, Fire, Rescue, Etc. ) – Market (post-9/11) will materialize; Ex. : Packet. Hop 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 90 s No Application Has Achieved Mass Market Status, Yet… Aerospace Electronic Systems 6/4/2004 - 4
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? w Do dynamic spectrum sharing approaches address this challenge? – This approach will be resisted by the current service providers w Not a problem if there is no incumbent/infrastructure, which is the case for many areas Aerospace Electronic Systems 6/4/2004 - 5
Mobile, Wireless (Kids) Gaming • Hand Held Gaming Device – Affordable ($100 s) – Hardened for use by kids – Standalone as well as able to attach to infrastructure (hot spots, etc. ) Display and Entry Wireless MAC/PHY Network Routing Geolocation Range Finder? Games Other Applications Batter y Palm, i. Paq, etc. 802. 11 x Software GPS, IMU, map, compass Laser tape measure Doom, D and D, etc. Calendar, Datebook, Tetris, etc. 4 hours of battery life before recharge Exists ~$200 Exists ~$100 Exists Free w/ Device Develop Target of $100? Exists $35 Develop - $ and free Exists - Free w/ device Exists Free w/ device • 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 (PS 2/XBox-like) Would Lower Cost to $100 s – Do. D wants this Now for every dismount but can’t afford it (batteries) – Other applications and markets would develop Aerospace Electronic Systems 6/4/2004 - 6
Stepping on My Technical Soapbox… • Default Media Access Control (MAC) approaches (e. g. 802. 11 x) are inefficient when used in Mesh/MANET contexts vice the AP/cellular context for which they were designed – Hidden terminal/exposed node; Qo. S/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 Qo. S – Timing is now free from GPS – Needs attention in standards bodies which traditionally are routing focused Aerospace Electronic Systems 6/4/2004 - 7
