Algorithm 2: Steps of fog computing Layer
Step 1:	Retrieve the data from repository on fog layer.
Step 2:	Perform the preprocessing technique on collected data.
Step 3:	Applied random forest classifier for dengue prediction (Algorithm 3).
Step 4:	Adopted Gini Index based feature selection algorithm.
Step 5:	Monitor the dengue affected patients and generate an alert message (Algorithm 4).
Step 6:	Store the data on fog computing layer for future perspective.
