Single-hop unicast

The unicast module sends a packet to an identified single-hop neighbor.

The unicast primitive uses the broadcast primitive and adds the single-hop receiver address attribute to the outgoing packets. For incoming packets, the unicast module inspects the single-hop receiver address attribute and discards the packet if the address does not match the address of the node.

Channels

The unicast module uses 1 channel.
