Wireless Sensor Network using MATLAB

I want a WSN simulation in MATLAB, there is no hardware. I want to create a simulation with multiple clusters, and each cluster has a few slave nodes and one master node. The cluster should be connected to a database. I want the slave nodes (sensors) to read data from an excel sheet that I already have. Then I want the data sent to the master node and then to the database where there will be a machine learning algorithm that will take the data as inputs (the algorithm is already finished). Or if it is possible, to add the algorithm to the master nodes and make the computations there instead of the database, in a way to parallelize and divide the computations. This should be done in MATLAB.
