Falvo II, KC5TJA/6 2005 "Because the amateur service isn't bound by commercial interests looking to maintain compatibility with existing infrastructures, we needn't be hindered with past technologies." Requirements for the NgARN: * an all-wireless internetwork * affordable * easy to deploy * advance the current state of the art somehow (to develop and debug technology that can later be applied to non-amateur fields) * provide excellent return on investment Samuel's article focuses on communication between amateur radio operators; perhaps the same technology (or at least some of the standards layers) can be applied to [http://wsn.oversigma.com/ wireless sensor networks]. === autobaud === Often we have some "slow" devices and some "fast" devices. Even with 2 identical devices, often they can communicate "fast" when they are close to each other, but need to down-shift to a slower speed when they are far apart and/or there is more environmental noise. It would be nice if the protocol provided support so that any 2 communicating devices could automatically switch to the "best" speed, rather than manually setting the baud rate. * [http://www.psocdeveloper.com/forums/viewtopic.php?t=3693 psocdeveloper: auto detect baudrate] * [http://en.wikipedia.org/wiki/Automatic_baud_rate_detection Wikipedia: automatic baud rate detection] == mesh network == I assume that we want the NgARN to be a "mesh network" with some "ad-hoc routing protocol". In other words, * We want new nodes to detect the network and start helping carry traffic automatically, with a minimum of configuring the new nodes or the rest of the network. * We want the network to automatically "heal" when a node moves to a different location or goes completely offline. related links: * http://communitywiki.org/MeshNetwork * http://opensourcemesh.org/ * https://www.open-mesh.net/ * http://en.wikipedia.org/wiki/List_of_ad-hoc_routing_protocols * http://www.reprap.org/bin/view/Main/ASelf-organisingPeer-to-peerCell-basedWi-FiNetwork The Open Phone: A self-organising peer-to-peer cell-based wi-fi network * Lots of people are developing (incompatible) protocols for wireless sensor networks: http://wsn.oversigma.com/wiki/index.php/WSN_Platforms#Standard_wireless_protocols == discussion == "The biggest reason why wireless projects are being held up is a lack of standards." -- Paul Sereiko, as quoted by Dan Hebert in [http://www.controldesign.com/articles/2007/170.html "The Invisible Threat"] 2007 CategoryStandard
