1. A node of a multi-node network, the node comprising:
a communications interface including at least one paired directional antenna element comprising 1) a transmit (Tx) antenna element steerable to a first direction and 2) a receive (Rx) antenna element oriented opposite the first direction;
and
a controller operatively coupled to the communications interface, the controller including one or more processors and configured to, for one or more first time intervals:
transmit, via the at least one Tx antenna element, at least one message in a transmit (Tx) direction within a transmit (Tx) region;
and
receive, via the at least one Rx antenna element pointed in the Rx direction, at least one message transmitted by a neighbor node of the network, the Rx direction within a receive (Rx) region;
the controller configured to, for one or more second time intervals subsequent to the first time intervals:
transmit, via the at least one Tx antenna element, at least one message in a Tx direction within the Rx region;
and
receive, via the at least one Rx antenna element, at least one message in a Rx direction within the Tx region.
