    摘要: An embodiment of the present invention provides an apparatus, comprising a transceiver capable of dynamic cluster-based node sleep/wake scheduling by integrating application information such as scheduled data transfers with the sleep/wake scheduling, wherein the nodes may sleep immediately after a scheduled data transmission. Further, the nodes may intelligently and automatically choose to sleep based on the ongoing communication of its neighbors and the apparatus may be part of a wireless sensor network. The nodes may consist of battery-operated computing and sensing devices that collaborate to deliver sensed data and the delivery of the sensed data may be over multiple hops between multiple nodes.

    摘要: An embodiment of the present invention provides an apparatus, comprising a transceiver capable of dynamic cluster-based sleep/wake scheduling using hierarchical routing, cluster formation, and sleep-wake synchronization. The hierarchical routing may comprise a sink node capable of sending periodic route updates, which may propagate through a network to regular nodes and the route updates may include metrics allowing the regular nodes to select a “best” path to the sink node. The metrics may include hop count or end-to-end reliability and the regular node may track a next hop which optimizes the metric; and packets originating or forwarded by the regular node to the sink node may be sent to the next hop. Further, the route updates may propagate across a backbone network to cluster heads.

    摘要: 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.
