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.
Claims16
A method for managing power consumption at each node set in a tree-based, Time-Division Multiple Access (TDMA) multi-hop wireless network, which includes a set of nodes powered by a battery, the method comprising:
- relinquishing initial role of the node 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 and/or stops acknowledging beacons from a parent node;
- and
- wherein said each node has a lower power consumption in this new role than it had in its initial role.
An article of manufacture tangibly embodying a non-transitory computer-readable program code which, when executed, causes the computer program to implement the steps of a method for managing power consumption in a tree-based TDMA multi-hop wireless network of nodes, wherein the method comprises:
- relinquishing initial role of the node 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 and/or stops acknowledging beacons from a parent node;
- and
- wherein said each node has a lower power consumption in this new role than it had in its initial role.
