Network power optimization via white lists

摘要

A device and method for controlling radio power in a wireless sensor network. A wireless sensor device includes a wireless transceiver, a white list generator, and power control logic. The wireless transceiver is configured to transmit and receive via a wireless sensor network. The white list generator configured to identify wireless sensor nodes that communicate directly with the wireless sensor device via the wireless sensor network, to identify time slots assigned for communication between the wireless sensor device and each of the identified wireless sensor nodes, and to create and maintain a list of the identified wireless sensor nodes and corresponding time slots. The power control logic is configured to power the transceiver for reception of transmissions from each identified wireless sensor node based on the identified time slots corresponding to the identified wireless sensor node provided in the list.
