Abstract
In a wireless mesh network of network nodes, there is identified a first subset of the nodes that have a direct connection to at least one end user, and a second subset of nodes that are necessary to maintain connections among the end users. The first subset is exclusive of the second subset. Nodes that are not within either the first subset or the second subset enter a power savings mode, which may include shutting down completely for a predetermined period. This enables power savings in that only the minimum number of nodes that are necessary to maintain connectivity of the end users may remain powered. A centralized node may make the decisions and inform individual nodes to shut down, or each node may run the same algorithm using the same input information and determine its own shutdown decision.
