DSPN和熵权双基法在WLAN网络可靠性评估中的应用

摘要

Deterministic and Stochastic Petri Net (DSPN) model has the superity in the area of discrete dynamic event system description.In this artcle, such superiority of DSPN is used to model the RTS/CTS mechanism of WLAN communication protocol.Moreover two important performance parameters of WLAN are calculated, and their reliabilities evaluation are conducted using entropy weigh dual-base method.%基于DSPN模型描述离散动态事件系统的优越性.对WLAN通信协议的RTS/CTS机制进行建模,计算出了WLAN的两个重要性能指标,并利用熵权双基法对其进行了可靠性评估.
