Recent and future communications networks have to provide QoS guarantees for a rapidly growing number of various telecommunication services, which can be ensured by application of an efficient MAC layer. Particularly, per-packet reservation MAC protocols are efficient ensuring a good network utilization and realization of QoS for various telecommunications services. However, per-packet reservation protocols suffers from an unfairness because network stations achieve different relative data throughput depending on the traffic characteristics of used services. A fair scheduling between network stations can be ensured if offered data rate per station is known, which is unfortunately not the case. In this investigation it is shown that the offered data rate can be successfully estimated by calculation of so-called effective requesting period per network station, which can be used for implementation of a fair scheduling mechanism. The results show a significant improvement of the fairness behavior in the network if the fair scheduling is applied.
