I consider a peer-to-peer network(blockchain) with N node where a node send its own data(transactions or block) to other peer nodes.
I would like to limit data replication in my network and show it with simulation.
For example, I have 7 nodes in the networks that I restrict the replication of special transaction or data in the network where they are replicated between only 3 nodes(not 7 nodes).
I was wonder if you could tell me which simulator is the best(NS3 or core,for example, my time is limited to learn it) and how can I show decreasing the network overhead(comparing in 2 conditions: 1) a node sends data to other 6 node 2) that node sends data to only 2 other nodes)
and other parameters such as performance evaluation of network?

Although you can use NS3 or VIBES, I think your problem is not bounded to blockchain problem domain and you can use any capable network simulator software. Anyway, I recommend OPNET first and if not possible, OMNET++ regarding to the learning curve.
CORE (https://www.nrl.navy.mil/itd/ncs/products/core) is not a simulator, it is a network emulator and it actually virtualizes the networking stack so you will get more realistic results from it. You can also run full bash scripts in the emulated nodes, it's as if you are running a linux machine in each node.
Have a look at this simulator, which is built for Bitcoin network using NS3 https://github.com/arthurgervais/Bitcoin-Simulator,, hope it helps
Is anybody help me how NS3 used for blockchain implementation in the transportation of supply chain simulation, please.
Hi, your best bet is to use any network simulator. One of the good yet complex ones is NS3, for which the following proves useful to learn.

Shadow ( https://shadow.github.io/) seems to be a unique tool as it's both an emulator and a simulator. It says it runs real applications like Tor and Bitcoin over a simulated network topology.
Hyperledger wants to use Shadow in the their Umbra project but backed off (https://wiki.hyperledger.org/display/INTERN/Hyperledger+Umbra%3A+Simulating+Hyperledger+Blockchains+using+Mininet)
