Abstract

The IEEE 802.11s standard defines a novel deterministic channel access method called MCCA. In preliminarily reserved time intervals, MCCA allows packet transmission from the owner of the reservation to the intended receiver, while their neighbors are forbidden to access the channel. Such a protection decreases the interference from hidden stations, allowing to improve reliability of transmission between two stations, which makes MCCA a promising method to transmit real-time multimedia streams with parameterized QoS support. However, both random noise and interference from the stations out of one-hop neighborhood may cause transmission errors, increasing packet loss ratio. In this paper, we consider various mechanisms for protecting reservations from interference and propose a method to find the amount of reserved channel resources and the type of protection needed to meet QoS requirements while transmitting the data with MCCA in case of varying channel conditions.
