Spectral Analysis of the Queueing Model for IEEE 802.16 Wireless Networks Reviewed International journal

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：Springer
Worldwide Interoperability for microwave access (WiMAX) based on the IEEE 802.16 standard has become one of the most promising wireless technologies and been widely
applied for the provision of broadband wireless access in the fourth-generation communication networks. In this paper, we investigate the performance of IEEE 802.16 wireless networks with the contention-based bandwidth (BW) request scheme in non-saturation mode.
Taking into account the buffer content as well as the backoff stage and backoff counter processes , we model the dynamics of the contention BW request scheme by a 3-dimensional Markov chain. We derive its steady state probability using the spectral analysis method and
obtain some key performance measures such as system efficiency, loss probability, mean number of packets in the buffer and mean head-of-line (HoL) delay. These results are useful in determining an optimization configuration for the efficient operation of the IEEE 802.16 wireless networks.DOI： 10.1007/s11277-02-08810-8

n the majority of IEEE 802.11 series wireless networks, the quality of service (QoS) requirements are
related to the queueing behavior of buffers in mobile stations, e.g., the buffer stability, overflow probability and packet delay, etc.. Thus, it is important to accurately evaluate the performance of such networks in non-saturation environments. In this paper, we analyze the IEEE 802.11e enhanced distributed channel access (EDCA) wireless network under finite load. We develop an analysis model by a 3-dimensional Markov chain and derive its steady state distribution using the spectral method. We present a variety of performance measures including the buffer stability, the collision probability, the non-saturation throughput and the probability generating function of Head-of-Line delay (HoL-delay). For IEEE 802.11e EDCA wireless networks, these results are very useful in optimizing the network architecture and system parameters under the given QoS requirements.DOI： 10.1007/s11276-020-02324-0
