Power conservation for devices is facilitated based on likelihood of power usage level. An example method can comprise determining, by a first device comprising a processor, that a second device is within a defined proximity of a third device, wherein the third device is determined to be operating in a mode according to a first power consumption operation that satisfies a defined condition, and wherein the operating in the mode according to the first power consumption operation is based on the third device being located at a defined location. The method can also comprise facilitating, by the first device, modification of the mode of the third device based on a determination of a likelihood of usage of a second power consumption operation by the third device. In various embodiments, the third device is configured to operate according to the power save mode or the extended discontinuous reception mode.

A system for reducing power consumption in a wireless network includes a station (e.g., Wi-Fi sensor) and an access point in wireless communication with the station. The station has at least a low-power sleep mode and an active mode. The system can be configured to assign a static Internet Protocol (IP) address to the station and disable re-negotiation of an encryption key while the station is in sleep mode. The system can further be configured to force the station to communicate via 802.11g and to transmit data to a proxy service while in active mode before returning to sleep mode upon receiving a response from the proxy service. Further, an association timeout period associated with the station can be configured to be at least twice as long as a wake-up period associated with the station.
