RE: 9$ CHIP computer - j.crater - Dec-26-2016
@wavic While I like the idea, it is far too advanced for me at this point :D But I see it is another Kickstarter success, same as Chip. That tells a lot about public interest/support for this kind of projects and it is encouraging.

The Parallella is available (16 core risc) for $99 here https://www.parallella.org/
Keep in mind that Moore's Law is now considered obsolete (at least at MIT) with the advent of the gallium arsenide switch (see my previous post http://python-forum.io/Thread-New-old-news-tiniest-transistor-ever-and-not-in-silicon)

Mesh Networks and reliability
I am going to ramble here, It's the best way I know of to begin the process of
forming solid ideas (called a plan).
It's really not a new idea, my first experience with the internet was through a microwave
connection to MIT, some 10 miles from our building (I believe one repeater, which just
happened to be on op of the hill our building was on) back around 1986.
One idea that I am tossing around in my head is ... why not make every node have two
modes, repeater and terminal node.
Mesh Networks becoming commercial product:
This is a ground floor opportunity for what I think is going to become the next
great thing in networking.
Here's one company's blog on what they are doing with mesh networking.
---------------
All I'm trying to do here is start a discussion, and I think perhaps this is a good subject for
the forums chat server.
Anyone game?
RE: 9$ CHIP computer - j.crater - Dec-26-2016
I enjoy brainstorming sessions, so why not!
Are you considering a piece of hardware (with proper SW of course) which can act both as a node and repeater. Or is it a new network protocol design / current protocol improvement?
I'm fine with bloating the chat server with this discussion, if it can be made separate from the general chat.
RE: 9$ CHIP computer - Larz60+ - Dec-27-2016
Without much thought about how, I was thinking the same device.
I need to start doing some serious reading about what's currently being done. My
nephew was here for the holidays, so I was picking his brain yesterday, trying to
find out as much as I could about their New York setup. He didn't get into details about
their mesh setup. It uses DigiMesh firmware.
paper here
He did say that lost packets were a big issue.
I don't yet know what type of protocol is being used.
I would expect something close to tcp/ip, where lost packets should be retransmitted so
long as proper acknowledgements were in place.
... More after some rudimentary education.

Hm! I see a big place for MITM attacks in this kind of network.

As are 95% of HTTPS servers.
Quote:With companies like Let's Encrypt offering free certificates and automated management tools, it is also easier than ever to deploy an HTTPS website that will be trusted by all modern browsers.Have to use something like Strict-Transport-Security
There are several papers available on the subject:
Detecting Man-in-the-Middle and Wormhole Attacks in Wireless Mesh Networks
Security Issues in Wireless Mesh Networks
Accountability for wireless LANs, ad hoc networks, and wireless mesh networks
Book - Security of Self-Organizing Networks
and a lot more
Since I love to read, I'll start with these.
It may end up being more than I want to take on, but so far I'm still interested.

Mesh networks are going to save the civilization if we face a zombie apocalypse though

There are 5 links here, which one, IEEE?
RE: 9$ CHIP computer - j.crater - Dec-27-2016
@Larz60+
I'm sorry to say that I am not well educated in networking. I can invest time to start with basics. But I will lag behind the depth of understanding needed to be of much use in this case.
Atm I might be of some use with hardware related things. However, if you have suggested readings for me on newtorking subjects (apart from what you already linked), I will dive into it. Except for very thick volumes, frankly.

I believe @wavic was thinking of Let's Encrypt, since I was wondering the same, and IEEE has "institutional" and "personal" sign in.
