| Popis: | 98 In a wireless network, how to allocate resources efficiently and fairly is an important issue. Since there are no specified scheduling mechanisms to let the base station (BS) allocate bandwidth to the subscriber station (SS) in the IEEE 802.16 standard, we propose two new scheduling mechanisms considering the nature of IEEE 802.16, quality of service (QoS), and fairness in this thesis. Our proposed scheduling mechanisms can fairly determine priorities of connections and the amount of resource to be allocated according to the QoS parameters and throughput of connections so that both QoS and fairness can be enhanced. Through simulations, we show that our proposed scheduling mechanisms can outperform the closely related mechanisms in the literature in terms of throughput, average packet delay, and fairness. |
