In this study, we show that high-speed IEEE 802.11n wireless ad hoc networks suffer from loss of efficiency at network layer. Through extensive simulations, we find the problems of unfairness among traffic flows, packet drops, increased delay and decreased throughput in these networks. We believe the root cause of these problems is RTS Threshold implying that setting an appropriate threshold value can solve most of the problems. To the best of our knowledge, this is the first work that finds this problem and to solve it, we propose an analytical model by which the RTS threshold is set. The simulation shows that this setting can improve the efficiency of IEEE 802.11n networks up to 25% in terms of throughput.
