Abstract :
The IEEE 802.16 standard defines MAC and Physical layers for broadband wireless networks called WiMAX, however, it does not define the scheduling algorithm for the uplink and downlink traffic. In this paper, a predictive scheduling algorithm for uplink traffic in IEEE 802.16 networks is proposed. The proposed algorithm uses the cross-layer approach and is applied on the queue of the bandwidth requests messages in the BS. For each bandwidth request, the proposed algorithm calculates a deadline in accordance with the Modulation and Coding Schemes (MCS). Thus, the proposed algorithm reduces the average delay on the access network and uses the resource, in the environment with several burst profiles, in a fair and efficient way. Its evaluation by means of modeling and simulation showed satisfactory results.
