ABSTRACT:
Network node control is described that includes node wakeup scheduling that reduces the energy consumption of levels of nodes and reduces the delay of information transfer through the network. The node wakeup scheduling includes a crossed ladder pattern that combines two wakeups in one level. The node wakeup scheduling also includes an adaptive version of the crossed ladder pattern that changes the wakeup patterns of the crossed ladder over time to provide uniform energy savings. The network node control also includes the use of multiple trees to transfer information through a network. This multi-parent node assignment assigns multiple parents with different wakeup schedules to each node in the network. This multi-parent assignment reduces the delay in transmission of information through the network and also increases energy efficiency in the nodes.
