I could find some real life traces like Infocom'06, MIT etc for network simulation. But I would like to record some own traces ( In our Location ) and use it for my simulation . how do i record the traces ?
If you want to record network simulations, you have to build your own Agent. This agent should be distributed on the network nodes and collect your desired parameters. You can check some distributed component simulation materials.
If you want to produce your own dataset and build an extensive collection of packet traces, you can use one of the networking monitoring tools recommended by the Center for Applied Internet Data Analysis (CAIDA) and collect traffic information (locally or remotely):
