The Effect of RTS/CTS Frames on the Performance of Ad Hoc-Based Mobile LAN

This paper analyzes the effect of RTS (Request To Send) and CTS (Clear To Send) frames on the network performance in the ad hoc-based mobile LAN. An ad hoc-based mobile LAN with two clients and one server is simulated using OPNET simulator to analyze network load, connection congestion window size and traffic received from each client in the FTP server. We found that both the connection congestion window size and network load about Clients are affected by the node mobility. The server terminates the FTP session with ClientA earlier if RTS/CTS is enabled. On the other hand, the server terminates the FTP session with ClientB later if RTS/CTS is enabled. We also identified that applying RTS/CTS scheme does not always improve the performance of the “traffic received from each client in the FTP server” in all network environments.
