ABSTRACT
In view of the characteristics of long propagation delay, hidden terminals and large users in LEO satellite to ground link environment, we adjust CTS_timeout according to the transmission distance, and the TDMA algorithm is introduced into the RTS/CTS access mechanism, an improved two-dimensional Markov model is proposed. Finally, we simulate the work flow of RTS/CTS mechanism under LEO satellite Wi-Fi network by MATLAB. The throughput performance of MAC layer is analyzed and the validity of Markov model is verified. Simulation results show that the system throughput is proportional to the transmission distance in the saturation state, and the lower the bit error rate, the longer the data frame length at which the highest throughput is achieved.

A New Method for Improving MAC Level Broadcast Receive Ratio Using 2-Phase RTS/CTS Handshakes Sequence
NBIS '09: Proceedings of the 2009 International Conference on Network-Based Information SystemsIEEE802.11DCF which is widely used wireless LAN standard employs RTS/CTS exchange for improving reliability of unicast transmission. But, broadcast receive ratio transmission is much lower than unicast transmission because the IEEE802.11DCF proceeds ...
Can multiple subchannels improve the delay performance of RTS/CTS-based MAC schemes?
We analyze the delay performance of RTS/CTS-based (Request-To-Send/Clear-To-Send) multi-channel MAC (Medium Access Control) schemes for wireless networks. These schemes usually employ multiple data subchannels for data transmission and one control ...
Successive-Capture Analysis of RTS/CTS in Ad-Hoc Networks
We consider a wireless ad-hoc network with random ALOHA transmissions between nodes. However nodes can decide to use the Request-to-Send (RTS) / Clear-to-Send (CTS) protocol for occasional long packets. Via the RTS/CTS protocol, nodes proactively make a ...
