Commotion Wireless
Commotion Wireless is an open-source wireless mesh network for electronic communication. The project was developed by the Open Technology Institute, and development included a $2 million grant from the United States Department of State in 2011 for use as a mobile ad hoc network (MANET), concomitant with the Arab Spring. It was preliminarily deployed in Detroit in late 2012, and launched generally in March 2013. The project has been called an "Internet in a Suitcase". Commotion 1.0, the first non- beta release, was launched on December 30, 2013. Commotion relies on several open source projects: OLSR, OpenWrt, OpenBTS, and Serval project.

Ubiquiti
Ubiquiti Inc. (formerly Ubiquiti Networks, Inc.) is an American technology company founded in San Jose, California, in 2003. Now based in New York City, Ubiquiti manufactures and sells wireless data communication and wired products for enterprises and homes under multiple brand names. On October 13, 2011, Ubiquiti had its initial public offering (IPO) at 7.04 million shares, at $15 per share, raising $30.5 million. Products Ubiquiti's first product line was its "Super Range" mini-PCI radio card series, which was followed by other wireless products. The company's Xtreme Range (XR) cards operated on non-standard IEEE 802.11 bands, which reduced the impact of congestion in the 2.4 GHz and 5.8 GHz bands. In August 2007 a group of Italian amateur radio operators set a distance world record for point-to-point links in the 5.8 GHz spectrum. Using two XR5 cards and a pair of 35 dBi dish antennas, the Italian team was able to establish a 304 km (about 188 mi) li ...

Serval Project
The Serval Project (often referred to as Serval) is a project financed by the Shuttleworth Foundation, as well as various other organisations and accepting individual donations. It is headquartered at Flinders University in Adelaide, Australia. The project aims to develop technology that can be used to create direct connections between cellular phones through their Wi-Fi interfaces, without the need of a mobile phone operator. The technology allows for live voice calls whenever the mesh is able to find a route between the participants. Text messages and other data can be communicated using a store and forward system called Rhizome, allowing communication over unlimited distances and without a stable live mesh connection between all participants. The Serval Project includes a collaborate mapping application intended to support disaster relief and recovery efforts. A "mesh extender" is being developed, which establishes a short range Serval mesh over WiFi and joins it with other more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenBTS
OpenBTS (Open Base Transceiver Station) is a software-based GSM access point, allowing standard GSM-compatible mobile phones to be used as SIP endpoints in Voice over IP (VoIP) networks. OpenBTS is open-source software developed and maintained by Range Networks. The public release of OpenBTS is notable for being the first free-software implementation of the lower three layers of the industry-standard GSM protocol stack. It is written in C++ and released as free software under the terms of version 3 of the GNU Affero General Public License. Open GSM infrastructure OpenBTS replaces the conventional GSM operator core network infrastructure from layer 3 upwards. Instead of relying on external base station controllers for radio resource management, OpenBTS units perform this function internally. Instead of forwarding call traffic through to an operator's mobile switching center, OpenBTS delivers calls via SIP to a VOIP soft switch (such as FreeSWITCH or yate) or PBX (such as Asteri ...

OpenWrt
OpenWrt (from ''open wireless router'') is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl, and BusyBox. All components have been optimized to be small enough to fit into the limited storage and memory available in home routers. OpenWrt is configured using a command-line interface (ash shell) or a web interface (LuCI). There are about 8000 optional software packages available for installation via the opkg package management system. OpenWrt can run on various types of devices, including CPE routers, residential gateways, smartphones, pocket computers (e.g. Ben NanoNote). It is also possible to run OpenWrt on personal computers and laptops.

Optimized Link State Routing Protocol
The Optimized Link State Routing Protocol (OLSR) is an IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol, which uses ''hello'' and ''topology control'' (TC) messages to discover and then disseminate link state information throughout the mobile ad hoc network. Individual nodes use this topology information to compute next hop destinations for all nodes in the network using shortest hop forwarding paths. Features specific to OLSR Link-state routing protocols such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) elect a ''designated router'' on every link to perform flooding of topology information. In wireless ad hoc networks, there is different notion of a link, packets can and do go out the same interface; hence, a different approach is needed in order to optimize the flooding process. Using Hello messages the OLSR prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Release Life Cycle
A software release life cycle is the sum of the stages of development and maturity for a piece of computer software ranging from its initial development to its eventual release, and including updated versions of the released version to help improve the software or fix software bugs still present in the software. There are several models for such a life cycle. A common method is that suggested by Microsoft, which divides software development into five phases: Pre-alpha, Alpha, Beta, Release candidate, and Stable. Pre-alpha refers to all activities performed during the software project before formal testing. The alpha phase generally begins when the software is feature complete but likely to contain several known or unknown bugs. The beta phase generally begins when the software is deemed feature complete, yet likely to contain several known or unknown bugs. Software in the production phase will generally have many more bugs in it than completed software, as well as speed/performan ...

Yahoo News
Yahoo! News is a news website that originated as an internet-based news aggregator by Yahoo!. The site was created by a Yahoo! software engineer named Brad Clawsie in August 1996. Articles originally came from news services such as the Associated Press, Reuters, Fox News, Al Jazeera, ABC News, ''USA Today'', CNN and BBC News. In 2001, Yahoo! News launched the first "most-emailed" page on the web. It was well-received as an innovative idea, expanding people's understanding of the impact that online news sources have on news consumption. Yahoo allowed comments for news articles until December 19, 2006, when commentary was disabled. Comments were re-enabled on March 2, 2010. By 2011, Yahoo had expanded its focus to include original content, as part of its plans to become a major media organization. Veteran journalists (including Walter Shapiro and Virginia Heffernan) were hired, while the website had a correspondent in the White House press corps for the first time in February 2012 ...
