at the beginning of a period called the beacon interval. e stations
that successfully exchange control packets during the ATIM window
start to transmit data immediately after the ATIM window expires.
When network load is increased, the stations waste energy in conten-
tion and retransmission operations, which are significant sources of
energy consumption and channel utilization degradation. A new bea-
con interval structure removes the ATIM window and divides the rest
of the beacon interval into equal interval time slots. e distributed
coordination function (DCF) with different interframe space and pri-
ority-based time-slot occupation is used to provide quality of service,
increase time in the doze state, and decrease ...
