Abstract:
1. A method comprising: determining a remaining battery power of a mobile device; generating battery status data based upon the determined remaining battery power; adjusting a listen interval between the mobile device and an access point of a wireless network based upon the remaining battery power; generating listen interval data based upon the adjusted listen interval; wirelessly transmitting an association request frame from the mobile device to the access point, the association request frame including the battery status data or the listen interval data; receiving the association request frame at the access point; adjusting, at the access point, a size of a buffer memory associated with the mobile device, wherein the size of the buffer memory is always increased when the battery status data is less than a first threshold or the listen interval data is greater than a second threshold, and the size of the buffer memory is maintained when the battery status data is greater than the first threshold or the listen interval data is less than the second threshold; and wirelessly transmitting an association response frame from the access point to the mobile device.
