无线媒体接入控制退避算法研究

Study on Backoff Algorithms for Wireless Medium Access Control

介绍了几种用于分布式无线媒体接入的典型退避算法,对几种算法的吞吐率、时延、公平性、稳定性等性能进行了比较和讨论,分别指出了它们的优点和不足,并说明了造成这些差异的内在原因。基于快速冲突解决算法和二阶竞争解决算法的基本思想,提出了一种高稳定性的二阶竞争快速冲突解决算法DSC-FCR。

This paper introduces several typical backoff algorithms used for distributed wireless channel access and discusses and compares their performances such as throughput.delay.fairness and stability.This paper illuminates their merits and flaws respectively,points out why these differences exist.Then,based on the basic concepts of fast collision resolution algorithm and dual stage contention resolution algorithm,proposes a high-stable dual stage contention with fast collision resolution algorithm DSC-FCR.
