Abstract

Providing quality of service to subscribers in wireless communication is one of the major issues in these days. An efficient packet scheduling algorithm in wireless network is one of the issues that require attention to quality of service provision. In heterogeneous wireless network, like WiMAX, whereby many packets of different Quality of service (QoS) are involved, packet scheduling becomes more difficult. This paper presents simple but efficient packet scheduling algorithm which uses earliest deadline first (EDF), wireless link condition and buffer state for scheduling UGS and rtPs packets. We estimate the link quality based on the total path loss and obtain SNR value which is use in chosen modulation for each packet to be schedule. The simulation shows that the proposed algorithm is efficient and has achieved higher throughput with negligible packet losses.
