Abstract: 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.
