Abstract: In one embodiment, a method comprises: receiving, by a network device in a data network, a wireless data packet containing new data; responding to the wireless data packet, by the network device, by initiating a prescribed randomized collision avoidance method requiring the network device to first wait at least a first half of a prescribed minimum contention interval before attempting transmission at a randomized position within a second half of the prescribed minimum contention interval; selectively retransmitting, by the network device, the wireless data packet based on determining, at the randomized position, that the network device has not received a prescribed number of copies of the wireless data packet; and selectively sending, by the network device to a path computation element in the data network, a message requesting membership in a dominating set in response to transmission of the wireless data packet by the network device.

Abstract: In one embodiment, a method comprises: promiscuously detecting, by a parent network device in a tree-based network topology, a data packet transmitted to a child network device attached to the parent network device, the data packet transmitted by a grandchild network device attached to the child network device; determining, by the parent network device, whether the data packet transmitted to the child network device is to be forwarded toward a destination via the parent network device; and the parent network device selectively initiating intercepted forwarding of the data packet toward the destination, on behalf of the child network device, based on determining that the data packet is to be forwarded toward the destination via the parent network device.
