fog computing resouce allocation using matlab

I'm working on fog computing resouce allocation problem, I want to implement a research paper https://ieeexplore.ieee.org/document/8233651.

I'm unable to understand that how to start implementing it, means how to create "The set of candidate cloud nodes, cand_set; The set of category for each cloud node, cate; The task need to be offloaded, task" as used input in the algorithm.

Anyone can help me to start it please....
