Abstract
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.
