An ARQ protocol simulator for the ECE 358 computer networks course.
Just run make in the top-level directory
And make clean to remove compiled object files and other generated data files
Usage: ./sim [-S npackets] [-N wsize] [-c bps] [-l plength] [-h hlength] [-t tau] [-b ber] [-d tratio] [-n]
-S(Number of packets that need to be sent successfully for the simulator to terminate)-N(The window size in packets. If this is set to 1 then ABP simulation is selected, otherwise GBN simulation will be performed)-c(The simulated link rate of the channel in bps)-l(The length of a packet in bytes)-h(The length of the frame header in bytes)-t(Tau, the propagation delay of the channel in seconds)-b(The bit error rate (must be between 0 and 1). Set to 0 for no bit errors)-d(The timeout period is set to this value (i.e. timeout/tau) times tau)-n(Specify NAK retransmission. If N=1 and this option is given, then the simulator used will be ABP_NAK)
scripts/run_ABPto run the ABP simulator and produce the required CSV filescripts/run_ABP_NAKto run the ABP_NAK simulator and produce the required CSV filescripts/run_GBNto run the GBN simulator and produce the required CSV filescripts/plotto generate png images of all the required plots. The above scripts must be run before this.
