This review is from: Wireless Mesh Networking: Architectures, Protocols and Standards (Wireless Networks and Mobile Communications) (Hardcover)
Wireless networking has been around for more than a decade, but mesh is a relatively recent revolution. This book edits together extensive research from about 50 global experts into an easy-to-read, fluid and authoritative account of this emerging technology and market.
The release of the 802.11 IEEE standard in 1997 set off a chain of developments including 802.11 a / b / g / and n that have revolutionized the lives of computer users – to a point where laptop/notebooks/netbooks tend to be a primary and fully capable method for network access today.
A similar effort, 802.11s, has been under development since at least 2003 – with the objective of establishing a mesh networking standard. This book does an excellent job raising many of the considerations behind that standard, at the same time it addresses other protocol and standards.
At the beginning of the Occupy Wall Street protests in New York City, Motherboard TV uncovered an unlikely hero in the thicket of the protest’s confusion. Meet Issac Wilder, the founder of The Free Network Foundation, a mesh networking system that allowed demonstrators access to free internet—that is until Zuccotti Park was ransacked and the Freedom Tower was confiscated and destroyed. See how DIY tech is influencing the state of modern day protesting and protecting our privacy in this video. Protests around the world, or even neighborhood networks will continue to be utilized and evolved as long as governments try to restrict people’s access to the internet in times of great need. This video takes a look at DIY mesh networks during the Occupy movement several years ago. We should see mesh networks pop up around the world during times of protest as this technology evolves.
No size limits, no cloud: Hands-on with BitTorrent's new file syncing software.
BitTorrent today released folder syncing software that replicates files across multiple computers using the same peer-to-peer file sharing technology that powers BitTorrent clients.
The free BitTorrent Sync application is labeled as being in the alpha stage, so it's not necessarily ready for prime-time, but it is publicly available for download and working as advertised on my home network.
BitTorrent, Inc. (yes, there is a legitimate company behind BitTorrent) took to its blog to announce the move from a pre-alpha, private program to the publicly available alpha. Additions since the private alpha include one-way synchronization, one-time secrets for sharing files with a friend or colleague, and the ability to exclude specific files and directories.
BitTorrent Sync provides “unlimited, secure file-syncing,” the company said. “You can use it for remote backup. Or, you can use it to transfer large folders of personal media between users and machines; editors and collaborators. It’s simple. It’s free. It’s the awesome power of P2P, applied to file-syncing.”
File transfers are encrypted, with private information never being stored on an external server or in the “cloud.”
“Since Sync is based on P2P and doesn’t require a pit-stop in the cloud, you can transfer files at the maximum speed supported by your network,” BitTorrent said. “BitTorrent Sync is specifically designed to handle large files, so you can sync original, high quality, uncompressed files.”

From Bruce Schneier:
What I've Been Thinking About
I have been thinking about the Internet and power: how the Internet affects power, and how power affects the Internet. Increasingly, those in power are using information technology to increase their power. This has many facets, including the following:
1. Ubiquitous surveillance for both government and corporate purposes — aided by cloud computing, social networking, and Internet-enabled everything — resulting in a world without any real privacy.
“Alexis Ohanian, the 29-year old founder of social news site Reddit, has partnered with the online advocacy group Fight for the Future to create what they’re calling the “Internet Defense League.” Ohanian describes the project, which they plan to officially launch next month, as a “Bat-Signal for the Internet.” Any website owner can sign up on the group’s website to add a bit of code to his or her site–or receive that code by email at the time of a certain campaign–that can be triggered in the case of a political crisis like SOPA, adding an activist call-to-action to all the sites involved, such as a widget or banner asking users to sign petitions, call lawmakers, or boycott companies.
“People who wish to be tapped can see, oh look, the Bat-Signal is up. Time to do something,” says Ohanian. “Whatever website you own, this is a way for you to be notified if something comes up and take some basic actions…If we aggregate everyone that’s doing it, the numbers start exploding.”
The embedded code on participating sites might do more than just display a mere banner ad, says Tiffiniy Cheng, co-director of Internet-focused political advocacy group Fight for the Future, and could even go as far as the blackout technique that Web activists used to successfully turn the tide against SOPA. “We’ll invent something at the time, and it will be some really unified and shocking action,” she says, hinting at techniques that would temporarily take over the entire appearance of willing sites. ”We’re creating the tools and the forms of protest that allow for viral organizing. That’s how the SOPA protests were able to get started and grow to the level they did.”
So far, Cheng says Reddit, imaging hosting site Imgur, the Electronic Frontier Foundation, viral content company Cheezburger Network, Mozilla and the non-profit Public Knowledge have all signed up. The group hopes that eventually thousands of sites–including those as small as a single user’s Tumblr page–will join the project.
Fight for the Future and Ohanian have both been focused most recently on defeating CISPA, the Cyber Intelligence Sharing and Protect Act. The bill, originally designed to allow sharing of information between the private sector and government agencies like the National Security Agency for cybersecurity purposes, was amended just before being passed in the House last month to allow companies to hand over any user data they wish to the government without regard for existing privacy laws, for reasons as vague as preventing computer “crime,” or “the protection of individuals from the danger of death or serious bodily harm.” One of two Senate versions of the bill is expected to come up for a vote in early June.
Fight for the Future last week launched an anti-CISPA site, Privacy is Awesome, asking users to call their senators and demand meetings to discuss the bill. And Ohanian has spoken out against the legislation as well, asking investors not to buy shares of Facebook’s newly-public stock to protest the company’s support for CISPA.
But CISPA protests have yet to match the fever pitch of anti-SOPA and anti-PIPA protests in January that led to boycotts of SOPA-supporting Web host GoDaddy, attacks by Anonymous against the Recording Industry of Association of America and the Motion Picture Assocation of America, and the blackout protests that included sites as popular as Reddit and Wikipedia. Most of Silicon Valley continues to support CISPA, including Facebook, Microsoft, IBM, Intel, Oracle and Symantec, with Google refusing to take a stand on either side of the issue.
Ohanian argues the challenge in maintaining political vigilance against laws that would harm the Internet is long-term endurance, rather than the ability to defeat any one piece of legislation.”You can only cry ‘Oh my gosh, they’re going to shut down the Internet’ so often,” he says. “We’ve scared [Congress] from doing anything as egregious as SOPA and PIPA again. But the new challenge is this endless series of smaller bills that try to unravel internet rights.”
The answer, Ohanian believes, is to foster a new level of engagement between Internet users and Congress that emphasizes digital rights and either educates ignorant lawmakers on Internet issues or helps to push them out of office. He cites an idea that he attributes to Cheezburger Network chief executive Ben Huh, that every Internet user should have their legislators’ phone numbers saved on their cell phone and ready to use on a regular basis.”
On a recent trip to Shenzhen, China, a group of MIT students discovered that you can buy a cell phone there for as little as $10. While the cost of mobile phones has continued to decrease over time, the fact that you can buy a gadget that can make phone calls and send text messages (and has a working battery) for that price is pretty astonishing. The head of MIT’s Media Lab, Joi Ito, reckons that these are likely the world’s cheapest phones.
A $10 price tag means that virtually anyone in the world can afford a mobile phone. Moreover, in parts of the world where basic phones are still more predominant than the “smart” variety gaining steam in the developed world, local infrastructure makes these gadgets more powerful than even smartphones in rich countries.
In Kenya, more than 30 percent of its GDP is fueled by M-Pesa, a mobile payments system that operates via text message. (See a video about M-Pesa here.) Though they may make life easier, smartphones in developed countries have not yet become anywhere near as important to driving economic growth.
Despite the rapid proliferation of smartphones in many countries, basic mobile phones still account for the majority of those used around the world. And given the tremendous economic possibilities for mobile payment systems to create economic growth, perhaps the most basic, cheapest cell phone might make it the world’s most useful.
