Here’s an interesting video about the design challenges associated with dissent networks built using mesh networks. Dissent networks are usually built using a mesh networks, and are often built in response to the censoring or limiting of Internet access by oppressive governments (think Egypt during the Arab Spring protests in 2011). The video suggests that there’s no silver bullet for building a mesh network that’s difficult to disrupt while also providing good performance. For example, using directional antennas improves signal range and reception, but it also makes the network more conspicuous and easier to trace; on the other hand, using omnidirectional antennas leads to a more robust network that is harder to jam, but it also leads to a lot more transmission collisions that decrease the network efficiency.
