Performance analysis of contention‐based access periods and service periods of 802.11ad hybrid medium access control

IET Networks, 2014
In this study, the authors present an analytical model for the contention‐based access periods (CBAPs) and service periods (SPs) as specified in the medium access control (MAC) layer of IEEE 802.11ad standards. The analytical model for CBAP is based on a
