APPARATUS AND METHOD FOR REDUCING POWER IN A WIRELESS SENSOR NETWORK

摘要

A wireless sensor device (300) includes a wireless transceiver (304), a white list generator (302) and power control logic (306). The wireless transceiver (304) is configured to transmit and receive via a wireless sensor network. The white list generator (302) is configured to identify wireless sensor nodes that communicate directly with the wireless sensor device (300) via the wireless sensor network, to identify time slots assigned for communication between the wireless sensor device (300) and each of the identified wireless sensor nodes, and to create and maintain a list (320) of the identified wireless sensor nodes and corresponding time slots. The power control logic (306) is configured to power the transceiver (304) 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 (320).
