Abstract

Method for managing power consumption in tree-based, Time-Division Multiple Access (TDMA), multi-hop wireless networks. The method includes at each node set the steps of: relinquishing its initial role in the network if a condition related to the power consumption of the node is not met; and adopting a new role in the network according to a TDMA protocol of said network; wherein the node stops emitting beacons to a child node thereof and/or stops acknowledging beacons from a parent node, and wherein each node has a lower power consumption in this new role than it had in its initial role.
