QoS Support for Bursty Traffic in Noisy Channel via Periodic Reservations

Ivanov A., Khorov E., Ляхов А. И.

The growth of the number of devices working at the same area, overlapping networks and multihop data transmission degrade the efficiency of contention based channel access. A number of deterministic channel access methods introduced in recent Wi-Fi standards allow to reserve a set of periodical time intervals, during which a single station can access channel without contention. Providing collision free transmission, these methods are favourable for real-time multimedia traffic which demands high quality of service (QoS). However, QoS provisioning for multimedia transmission is significantly complicated by the bursty nature of multimedia traffic and random noise inherent to wireless channels. In this paper, we propose an analytical model of multimedia transmission via periodic reservations considering both multimedia traffic bursty nature and random noise. The model can be used to find reservation parameters which allow to meet QoS requirements while transmitting multimedia data.
