Power management for multi-interface device clusters
First Claim
1. A computing device configured to participate in a power management cluster, the computing device comprising:
- a high-power network interface;
a low-power network interface;
a power management module comprising;
a power management cluster module configured to, at least, connect to at least one other computing device of a plurality of devices in the power management cluster through the low-power network interface so that the connected computing devices participate in a low-power peer-to-peer network via the low-power network interface, each of the plurality of devices has a probability of being designated as the lead device, the probability based on at least one of;
an amount of time a device has previously served as the lead device, a residual power of the device, or a mobility pattern of the device;
a lead designation module configured to, at least, designate at least one of the devices participating in the network as the lead device of the power management cluster; and
a high-power network monitoring module configured to, at least, connect to a high-power network access point through the high-power network interface in response to being designated lead device of the power management cluster such that the lead device is in communication with the high-power network and the low-power peer-to-peer network.

Abstract
Multi-interface devices with at least a high-power network interface and a low-power network interface may form into power management clusters. Power management clusters may be maintained over low-power networks associated with the low-power network interfaces. One or some relative few of the cluster participants may be designated lead devices. Designated lead devices participate in high-power networks as well as a low-power network of their power management cluster. Designated lead devices may monitor associated high-power networks for messages addressed to any participant in their power management cluster, and may notify a participant of the incoming message. In response, the participant may establish a high-power network connection to receive the message. In this way, each participant in the power management cluster receives a service quality benefit of a continuous high-power network connection, but only a relative few participants suffer the associated power expenditure at any given moment.
