具有多速率能力的IEEE分布式协调功能的建模与分析

Modelling and Analysis of the Distributed Coordination Function of IEEE 802.11 with Multirate Capability

F. Daneshgaran, M. Laddomada, F. Mesiti, M. Mondin

摘要:

该文致力于研究两个问题.一方面,它提出了一种多维马尔可夫状态转移模型,该模型通过包括传输状态和状态来表征在介质访问控制(MAC)层处的行为,所述传输状态说明了由于通过信道的传播所引起的错误而导致的分组传输失败,所述状态表征了当在站的队列中没有分组要被传输时的系统(以模拟非饱和业务条件)。另一方面,它提供了IEEE 802.11协议在数据链路层在饱和和非饱和业务条件下的吞吐量分析,同时考虑了瑞利衰落环境中的传输信道和多速率传输的影响。仿真结果与理论推导结果吻合较好,验证了所提模型的有效性。

英文摘要:

The aim of this paper is twofold. On one hand, it presents a multi-dimensional Markovian state transition model characterizing the behavior at the Medium Access Control (MAC) layer by including transmission states that account for packet transmission failures due to errors caused by propagation through the channel, along with a state characterizing the system when there are no packets to be transmitted in the queue of a station (to model non-saturated traffic conditions). On the other hand, it provides a throughput analysis of the IEEE 802.11 protocol at the data link layer in both saturated and non-saturated traffic conditions taking into account the impact of both transmission channel and multirate transmission in Rayleigh fading environment. Simulation results closely match the theoretical derivations confirming the effectiveness of the proposed model.
