Demonstration of TSCH adaptive channel selection based on background noise RSSI metric.
|
||||
TSCH stats must be enabled for the adaptive selection functionality to compile and work.
|
||||
|
||||
This code relies on the `os/services/channel-selection` library that implements
|
||||
the "RSSI upstream" adaptative channel selection strategy, described in the following paper:
|
||||
|
||||
A. Elsts, X. Fafoutis, G. Oikonomou and R. Piechocki. Adaptive Channel Selection in IEEE 802.15.4 TSCH Networks, 1st Global Internet of Things Summit, 2017.
