基于CTMC和状态空间模型的宽带无线接入网的QoS性能研究
The Research on QoS Performance of Broadband Wireless Access Network Based on CTMC and State Space Model
摘要
Abstract
In order to achieve the high QoS requirements demanded by many users in the same geographic area in a finite bandwidth case,the performance of providing packet-level QoS in the broadband wireless access network based on the IEEE 802.16 standard is studied in this paper.In practice,firstly,the arrival process and the traffic source is modelled by Batch Markov Arrival Process and Continuous Time Markov Chain and the more practical and more accurate queuing model is achieved.Then,based on the state space,a wireless access network system is modeled.By the in-depth analysis for the obtained system model and the queuing model achieved previously,the QoS performance metrics about this model,such as the average queue length,packet dropping probability,the queue throughput and the average packet delay,are obtained.The simulation results show that the proposed analytical model in this paper can improve and enhance the QoS performance metrics compared with other typical analytical models.关键词
