摘要 研究了无线局域网IEEE802.11协议的DCF(distributed coordination function)接入方式,在建模基础上进行算法改进,提出了一种新的节点自适应链路碰撞的退避算法NSAD(new self-adaptive DCF algorithm).大量的仿真实验表明,所提出的算法在吞吐量、公平性、丢包等方面较原DCF协议都有显著提高. This paper presents an in-depth analysis of the DCF (distributed coordination function) access mode of IEEE802.11 protocol. Based on the result of this study, the authors have developed a new self-adaptive wireless LAN MAC (medium access control) algorithm with the name of NSAD (new self-adaptive DCF algorithm). Simulation results show that NSAD is superior to DCF in all characters concerned (e.g. goodput, fairness, and packet drop rate).
