Function Documentation

void tsch_roots_add_address ( const linkaddr_t * root_address )

Add address as a potential RPL root that is a single-hop neighbor in the TSCH network.

Author: Atis Elsts atis..nosp@m.elst.nosp@m.s@gma.nosp@m.il.c.nosp@m.om For now, only add addresses that send TSCH EB's with join priority set to zero.

Parameters

root_address - the address of the root.

int tsch_roots_is_root ( const linkaddr_t * address )

Tests whether a given address belongs to a single-hop reachable root node in this network.

Parameters

address - the address to test

Returns: nonzero if the address belongs to a root node that is a single hop neighbor; zero otherwise.

Note: does not check if the address belongs to self, or to a root node more than a hop away!

void tsch_roots_set_self_to_root ( uint8_t is_root )

Set the root status of the local node.

Parameters

is_root - if nonzero, the local node becomes root; otherwise, it ceases to be root
