Mosh connections don't drop from merely wifi flipping around; you get replies back to the address and port the last uplink packet came from. You can just continue typing and a switch between Wi-Fi and mobile data (for example on a phone while sitting on public transit) shows as merely a lag spike during which typed characters will be predictive echoed by underlining them after an initial delay that serves to avoid flickering from rapidly retracted/changed predictions (predictions are underlined) during low-latency steady-state.

Mosh is like vnc or rdp for terminal contents: natively variable frame rate and somewhat adaptive predictive local echo for reducing latency perception; think client side cursor handling with vnc or with rdp I'd even assume there might be capability for client-side text echo rendering.

If you haven't tried mosh in situations with a mobile device that have you experience connection changes during usage, you don't know just how much better it is than "mere tmux over ssh".

I honestly don't know of a more resilient protocol than mosh that's in regular usage, other than possibly link-layer 802.11n aka "the Wi-Fi that got these 150 Mbit and those 300 Mbit and some 450 Mbit speed claims advertised onto the marker", where link-layer retransmissions and adaptive negotiation of coding parameters and actively-multipath-exploiting MIMO-OFDM (and AES crypto from WPA2) combine for a setup that hides radio interference to not be visible to higher level protocols beyond the unavoidable jitter of the retransmissions and varying throughput potentials from varying radio conditions.

Oh, I think when viewed regarding computers not the congestion control schemes adjusting the individual connection speeds, there'd also be BitTorrent with DHT and PEX that only needs an infohash: with 160 bits of hash a client seeded into the (mainline) DHT swarm can go and retrieve a (folder of) files from an infohash-specific swarm that's at least partially connected to the DHT (PEX takes care of broadening the connectivity among those that care about the specific infohash).

In the realm of digital coding schemes that are widely used but aren't of the "transmission" variety, there's also Redbook CD audio that starts off easy with lossless error correction, followed by perceptually effective lossy interpolation to cover severe scratches to the disc's surface.
