Deep Learning on WSN / Network Nodes

I have read the following article which finds the shortest / best flight between two countries using Networkx (library for Python) :

It is using the same Dijkstra’s algorithm to find the best path, so how it could be the part of deep learning, can some one please explain because I need to apply Deep learning on WSN network so that a node can decide where to send data, and I need some best resources which can help me that how much is this helpful and work has been done on it and what future work needs to be done.

Thanks
