data network

Data Networks is one of the master's courses that I took in the sixth semester of my undergraduate degree. The exercises of this lesson, which were of 4 different layers, were in the languages of "C++", MATLAB, NS3 emulator, Netanya, Wire Shark, Python, etc., which can be seen in the above folders.

topics:

• physical layer

• data link layer

  channel simulation and coding methods

  implementing Bitstiffing coding with channel simulation

  implemrnting 4B/5B coding with channel simulation

  implementing hamming code coder and decoder

  1.soft decision

  2.hard decision

  channel simulation bit one parity bit with BER analyis

  channel simulation with to 7 hamming code with BER analyis

  channel simulation with to 7 hamming code and parity bits with retrasmition methodwith BER analyis

  LDPC simulation channel and BER analyis

• mac layer

  CSMA multiple accsess method implementing in NS3 simulator (analysing NetAnim files and wireshark files)

  wifi multiple accsess control implementing in Ns3

• network layer

  leaky bucket and token bucket implementing on python and simulation for four diffrent arrival distributions

  finding sink tree using NS# simulator for given topology of nodes

• project

  HTTP simple sever implementing in class form to request GET and POST request in stantard form

  multi-thread server implementing
