In this paper, the authors propose an UpLink (UL) scheduling algorithm for Mobile WiMAX (IEEE 802.16e) system that satisfies the throughput and delay for the real and non real time application taking the adaptive Modulation and Coding Scheme (MCS) into consideration. The proposed algorithm works by adjusting the threshold which is imposed on the nrtPS queue. The threshold value here represents the number of bandwidth request messages in the nrtPS queue. WiMAX is a promising technology for a broadband wireless access which is based on wireless transmission methods defined by the standard IEEE 802.16.
