MAC Layer¶
LoRaWAN defines its MAC layer design for competitive uplink and time window for downlink. That is suitable for most of IoT DAQ systems. However, in some self-orgnized no-central-no-router network, competitive MAC layer is good enough. Therefore modified ALOHA algorithm is used, with RTS/CTS and time parameters.
DLL Layer¶
MLSE & MIB¶
LoRaWAN is well defined with MLSE and MIB.
X.25/AX.25¶
X.25 is a legacy protocol defined by CCITT/ITU. And AX.25 is a HAM version of X.25. Since AX.25 is still popular in HAM group, we are surveying the possibilities of put X.25 over LoRa MAC/DLL. It is just an option.
IPv6 over LoRa¶
IETF has a proposal of IPv6 over LoRa network.
