Highly efficient rate adaptation algorithm for IEEE 802.11ac
摘要
Abstract
Rate adaptation , which is one indispensable mechanism for the multi-rate wireless local area network ( WLAN) , is critical to the system performance . In this paper , we propose a highly efficient rate adaptation algorithm for IEEE 802.11ac based on the receiver's information feedback without modifying the MAC frame format . The basic idea is that the RTS frame is used to estimate the channel condition accurately , and then the CTS frame is sent back with the information of the chosen rate in a scrambling sequence . Moreover , according to the probability of the error received , the threshold of rate selection can be adaptively adjusted , thus further enhancing the stability of system performance . Simulation and verification by NS-3 show that the throughput performance of this algorithm outperforms that of three well-known rate adaptation solutions ( AARF , ONOE , and Minstrel) in different channel environments .关键词
