ABSTRACT:
An aggregation scheduler that determines which frames are to be aggregated in an aggregate at a specific time, and allocates a time and duration for each responder of the aggregate. The AP maintains information for each of its clients, including whether the client is in an awake or doze state and the time stamp arrival (TSA) for each frame received from the client by the AP. When an AP obtains channel access, it only aggregates frames for those clients that are awake. From the TSA and the voice packet arrival interval for the client, the AP can compute how many voice frames are waiting at the client since the AP received the last frame from the client. Knowing the number of voice frames waiting at the voice client and the transmission rate, enables the AP to accurately ascertain the response time and duration for the voice client.
