I have created a simulation environment for IoT network which consist of 10 nodes 1 edge node and 1 control center. I want to send data from nodes to the edge node.

Hi @Zara,
To send data from 10 IoT nodes to the edge node in MATLAB simulation, configure each node to transmit its data to the edge node’s IP address and port using UDP communication. The edge node listens on that port to receive data from all nodes.
You can understand by following example code:
%On each IoT node
u = udpport;
write(u, data, "string", "EdgeNode_IP", EdgeNode_Port);
%On each edge node
u = udpport("LocalPort", EdgeNode_Port);
data = read(u, u.NumBytesAvailable, "string");
For more details look into the following documentation:

Hope this helps!
