1. A method comprising:
assigning, by a coordinator node, a first network address and a first time slot to a first stationary network node (SNN);
assigning, by the coordinator node, a second network address and a second time slot to a second SNN, wherein the assigning, by the coordinator node, of the first network address and the first time slot to the first SNN occurs before a mobile network node (MNN) has joined a wireless network;
receiving, by the MNN, a multicast address over the wireless network, wherein the multicast address addresses the first and second SNNs;
receiving, by the MNN, first downlink data from the first SNN at the first network address during the first time slot, the first downlink data not being received via the second SNN;
receiving, by the MNN, second downlink data from the second SNN at the second network address during the second time slot, the second downlink data not being received via the first SNN; and
communicating, by the MNN, uplink data to the first SNN or the second SNN using the received multicast address.
