Evaluation of different RAAs with TCP Westwood and TCP Westwood+

Files included

1. twoWayFlowTest.cc - the testbed for the evaluation

   • The file contains the testbed that is used for the evaluation
   • It uses a dumbell topology where there are equal number of wifi nodes on both sides of the p2p link. Half of the pairs from these have a TCP Westwood/Westwood+ flow and the rest of the pairs have a TCP NewReno flow in the opposite direction.
   • Relevant Commandline Arguments :-
     • nWifi (int) :- Number of wireless nodes(2-7)
     • raa (string) :- RAA variants to be used (Arf/ Aarf/ Aarfcd/ Onoe/ Minstrel etc.)
     • tcp (string) :- TCP variant to be used (TcpWestwood / TcpWestwoodPlus)
     • p2pRate (int) :- point to point link data rate in Mbps
     • p2pDelay (int) :- point to point link delay duration in Milliseconds

2. graphPlotter.py - script to generate graphs of throughput and delay from results obtained

   • The testbed evaluates avg Throughput and avg Delay for the whole network in intervals of 0.2 seconds the graphPlotter script uses the data to plot graphs

3. runExperiments.sh - shell script to run tests by varying number of wifi nodes from 2 to 7 and using the above mentioned RAAs along with TCP Westwood and TCP Westwood+ then plot the graphs for the results obtained.

4. create_RNG_graphs.ipynb-ipython notebook to generate graphs of cummulative throughput and cummulative delay from the results obtained

Output for 4 wifi nodes on each side of the p2p link and 2 Westwood/Westwood+ flows and 2 TCP NewReno flows in opposite direction
