摘要

我们提出了一个分析模型来评估IEEE 802.11分布式协调函数(DCF)在无线光纤(RoF)无线局域网中使用和不使用RTS/CTS握手的性能。该模型捕获了在非饱和流量条件下,假设缓冲区大小较大的竞争节点和隐藏终端的影响。考虑了光纤传输延迟的影响。通过计算机仿真验证了所提模型的有效性。给出了基于该模型的RoF网络综合性能评价和仿真结果。

Performance analysis of IEEE 802.11 distributed coordination function in presence of hidden stations under non-saturated conditions with infinite buffer in radio-over-fiber wireless LANs
We present an analytical model to evaluate the performance of the IEEE 802.11 Distributed Coordination Function (DCF) with and without the RTS/CTS handshake in radio-over-fiber (RoF) wireless LANs. The model captures the effects of contending nodes as well as hidden terminals under non-saturated traffic conditions assuming large buffer sizes. The effect of fiber propagation delay is considered. The proposed models are validated using computer simulations. Comprehensive performance evaluations of RoF networks obtained from the proposed model as well as simulations are presented.
