Wireless network communications utilizing routing information. A group of nodes of a wireless network are organized into one or more hierarchical clusters based, at least in part, on routing information corresponding to a path between a selected node and a cluster head node. A sleep state and an awake state are scheduled for each node in the cluster so that each node in the cluster transitions from a sleep state to an awake state at a selected time to receive transmissions from child nodes and to forward data the received data to a parent node and to transition to the sleep state, wherein the nodes of a cluster do not all transition from the sleep state to the awake state at substantially the same time.
