Patent ID: 8488500

Claim:
A system for managing power consumption of a device node coupled to a communication node of a communication network by way of a communication link, the system comprising: a control node coupled to the communication node and configured for: learning an activity pattern associated with the device node, where learning the activity pattern includes monitoring, by way of the communication link, activities undertaken at the device node; estimating future activity of the device node based at least in part on the learned activity pattern, where the estimated future activity of the device node is based on a probability value that the device node will be active at a future time and wherein the probability value is calculated by one or more linear filters or non-linear filters; automatically generating a command based on the estimated future activity of the device node; and sending the command to the device node, through the communication link, to set the device node into a power management mode associated with the estimated future activity of the device node.
