i want to create a wireless sensor network with a source node,intermediate nodes and sink node with multiple paths from source to sink through intermediate nodes. The problem which i am facing is that when i want to connect more than one intermediate node with sink then it gives an error that "sink.network.in is already connect" means i can make connection of only one node with sink node, please help me to learn to make multiple connections with sink node.
This has nothing to do with MIMO, this is just because your sink isn't correctly defined. In your sink class, rather than just having a single gate, make it a vector:
simple Sink {
gates:
input in[];
}
You can also explicitly specify the size of this vector (i.e. put a maximum number of incoming connections); you can also add the @loose keyword after in[] or in[N] to allow inputs to be unconnected. Similarly inout instead of in etc.
It is all documented at the attached link.

U hv to use MIMO system !! Then this problem will be reslove !!

I suggest you to try the Castalia framework. It is designed typicallly for Wireless Sensor
