Abstract
A method of communicating between a wireless security device and a security server through an access point includes estimating a link latency between a time of transmission of a message from the wireless security device and a time at which a response is received from the security server. A polling mode is enabled in which the access point will hold messages received by the access point that are directed to the wireless security device while the device is in a sleep state, without discarding the messages for a threshold period of time. The wireless security device may be placed in a sleep state and woken after a wake time determined based on the estimated link latency, and receives any messages received by the access point during the sleep state.
