Abstract
In the paper, we present an analytical study of multimedia stream transmission with the reservation-based channel access method called MCCA in IEEE 802.11s mesh networks. Various aspects of MCCA have been already studied under the assumption that the reservation guarantees successful transmission, no retries are needed and the period of reserved times is equal to the inter-arrival time of the input stream. However, recent papers reveal the fact that two-hop advertisement of reservations, as adopted in MCCA, fails to completely defeat the interference affecting transmissions in addition to random noise. To keep the packet loss ratio (PLR) acceptable for a stream, period of reserved times may be shortened to allow packet retries. However, a packet of a stream is usually discarded when the packet delay reaches its threshold, making its contribution to the PLR. Also, additional reservations is a burden. In this paper, we propose an analytical model to find the maximal period of reserved times to keep the packet loss ratio and delay below thresholds, given the input stream bit rate and packet error rate.Keywords
