WLAN中基于门限调整的速率自适应策略
Rate Adaptation Strategy Based on Threshold Adjustment in WLAN
摘要
Abstract
This paper proposes a dynamic rate adaptation Media Access ControKMAC) strategy for multi-rate IEEE 802.11 wireless LAN based on threshold adjustment. In the protocol, two groups of success thresholds are set respectively for fast-fading and slow-fading wireless channels. Each group of success thresholds is tuned by an improved Binary Exponential Backoff(BEB) algorithm. Without any change to the current 802.11 standard, the protocol facilitates its implementation. Simulation results show that the new scheme outperforms other existing schemes including the Auto Rate Fallback(ARF) scheme and its variants.关键词
