Aspen Grove 1.0 is currently deployed on the goTenna Pro X and contains the ECHO routing protocol for broadcasting (shouts/PLIs), and an efficient lightweight medium access protocol called g-CSMA (g for goTenna). Aspen Grove 1.1 adds the VINE protocol and more improvements to the MAC protocol that we now call g-CSMA (g for goTenna), and many efficiencies to headers and sleep-wake cycling. Aspen Grove 1.2 will add the SPIN protocol at the MAC layer for significantly more efficient access resulting in hop and size increases.
