Dynamic Bandwidth Allocation for QoS in IEEE 802.16 Broadband Wireless Networks

Abstract

IEEE 802.16 broadband wireless access (BWA) technology is suitable for providing multimedia applications without accessing the wired networks directly. Although IEEE 802.16 standard well defines the quality of service (QoS) framework, it makes no specific recommendation with regard to the bandwidth allocation. In this paper, we propose an algorithm for allocating bandwidth in response to dynamic changes in the arrival rate such that the total bandwidth is efficiently utilized. key words: broadband wireless networks, IEEE 802.16, quality of service (QoS), scheduling algorithm

Bandwidth Allocation for QoS Using Adaptive Modulation and Coding in IEEE 802.16 Networks

“…In this subsection, we show the simulation results of the proposed algorithm. We compare our proposed algorithm with the algorithm in [3]. We assume that 4 SSs send data to the BS through uplink.…”

“…To accommodate AMC, we extend the time allocation algorithm in [3]. Consider only rtPS connections with delay requirements, T di .…”

“…However, the scheduler needs the information on the individual packets. In [3], [4], they have proposed a scheduling algorithm based on the queue information with the time varying arrival rate and the fixed data rate. In real wireless channels, SNR is changing with time due to many reasons like fading.…”
