I need to simulate and analyze different congestion control algorithms of TCP like Old Tahoe, Tahoe, Reno, New Reno, BIC and CUBIC and study the difference between these.
What may be a good simulation tool to do this?
I would recommend NetSim (https://www.tetcos.com) simulator which has these congestion control algorithms.
You may want to study the growth/reduction of the congestion window and this can be done using the packet trace or by capturing the packet in wireshark. I would recommend you use wireshark for the plots since it comes with a set of excellent analysis tools.
This pdf document also has an analysis of these congestion control algorithms

The general impression I get from people (and some personal experience) is that NS2/NS3 is too difficult to use/modify.
Do you have any other suggestions?
Ali H. Wheeb I would like to initially run some experiments and then do a project which may involve modifications to the congestion control algorithms.
Sai R N Thank you, the information you provided was very helpful. I will explore NetSim further.
Please see https://en.wikipedia.org/wiki/Ns_(simulator), and NS-2 development was stopped in 2010.
I would recommend a simulator like NETSIM or OPNET. You can go for the low price academic version. The open source tools are very complex and takes many months to understand & use.
NETSIM Standard Version V10.0 onwards tool is the best for congestion control algorithm.
You can use NS-3 to simulate different networks.
while coding, Using
"Config::SetDefault ("ns3::TcpL4Protocol::SocketType", TypeIdValue (TcpNewReno::GetTypeId ()))"
command can be beneficial. You can change the variant by changing the NewReno to other ones.
Actually, this link has done it for your network
