parameters will be like signal to noise ratio with respect to packet second parameter throughput third parameter is bit error rate with respect to packet

The parameters necessary to create a WSN node are that it have a distinguishable identity, even if only positional, so that when you change the state of one you are not changing the state of the others at the same time. This would, for example, not be the case if your implementation of nodes was as object oriented handles all pointing to a single "real" WSN node.
Everything else about WSN nodes is contextual and depends upon what properties they are to have for the purpose of your simulation. One of the more common properties for simulation purposes is some kind of absolute 3D position coordinates. But you need to be careful with that because it is not uncommon for the nodes not to start out knowing where they are and having to discover their relative positions, so you have to distinguish between what "you" know and what the nodes know.
How to make a link between nodes is part of what you need to research and model. It will probably involve one or more nodes broadcasting some identity information, and other nodes receiving that information. But which nodes to talk to directly and which nodes to talk to by relaying through another node is a matter to figure out (it might involve signal quality; it might involve time-slicing because nodes might not be able to transmit and receive simultaneously; it might involve deduced topology, spanning trees, limited memory to keep track of other nodes... there is no one right answer, there are different possibilities to meet different needs.)
