Package Switching Network. [2014]
Quadcopter delivery faces many challenges, one of which is their short range. One neat solution comes by shamelessly ripping off packet switching networks. With package relays from copter to copter, long deliveries become possible, but there is more to the story.
Routers
Physical sites, small warehouses constructed on top of leased roof space. Copters land, charge, trade packages depending on battery state, payload limits, reliability, range and other properties.
Build out open protocols to securely manage the following needs
(this should be written in Idris or Coq (they have C backends) for embedded platforms compiled with CompCert)
Machine operated air traffic control to prevent collisions.
Maybe use some fancy triangulation hardware to localize the copters more precisely.
Docking
quadcopters will need to charge their batteries, or provide a standard mechanism to swap them out.
