| help |
| Use CSMA-CA mechanism (listen-before-talk with exponential backoff) |
| to transmit packets. This is the most common way of mediating radio |
| channel access and fits most usage scenarios (see IEEE 802.15.4-2020, |
| sections 6.2.5.1 and 10.2.8). |
| |
| config NET_L2_IEEE802154_RADIO_ALOHA |
| bool "IEEE 802.15.4 Aloha medium access protocol (CCA mode 4)" |
| help |
| Use Aloha mechanism (send without any clear channel assessment) to |
| transmit packets. This is a simplistic way of transmitting packets |
| and fits low duty-cycle contexts where the radio spectrum is not |
| too heavily loaded (see IEEE 802.15.4-2020, section 10.2.8). The |
| current implementation does not randomize channel access. |
