Podcast conversation about mesh networking

Very interesting conversation podcast about mesh networking, the obstacles and the ways to circumvent them. Mentions the Open Garden project, a mesh networking utility for Android smartphones and for Windows and Mac laptops (support for iOS is coming). It’s a free app that turns your device into a mobile hot spot. No matter how you’re connected to the Net (Wi-Fi or cellular), it makes that connection shareable (over Bluetooth) to other Open Garden users. Likewise, if you’re running the product but don’t have a connection to the Net, and you’re near a user who does, this service seamlessly gets you online. The conversation describes the military’s application of mesh networking. I think we need the decentralization of connectivity that mesh networking offers. As during the “Arab spring”, governments can shut down the internet in its territory. Mesh networking will get round that. The sophistication of smartphones and other gadgets and the RF power available to consumers nowadays means that a decentralized network that can route around censorship will soon be a reality.

Compared to more centralized network architectures, the only way to shut down a mesh network is to shut down every single node in the network. Image from www.interference.cc

Mentions Open Garden, Tropos, plus technology such as utilities meters being part of a wireless mesh network so the meter reader doesn’t actually need physical access to read the meter.
