Copy this file in to scratch/ folder

To Change a new TCP protocol in command line, use the following statement.

$] ./waf --run "scratch/wifi-tcp --payloadSize=1000 --tcpVariant=TcpHighSpeed --pcap=true"

To change the payload

$] ./waf --run "scratch/wifi-tcp --payloadSize=2000"

Throughput of TcpNewReno is
1000 50.8712
1472 52.1583
2000 53.7056
