| Abstract: | Wireless Ad hoc networks mostly use IEEE 802.11 series of standards which provide several different modulation schemes and can achieve different data transmission rate. Rate adaptive MAC protocol in 802.11-based wireless Ad hoc networks can choose the appropriate data rate according to the channel quality estimation, make full use of multi-rate capability in physical layer and improve the network throughput. This paper analyzes the basic ideas of the rate adaptive MAC protocol, then introduces and discusses several typical rate adaptive MAC protocol proposed in recent years. Furthermore, the future research trend in this area is discussed. |
