The present disclosure provides a method and a device for decentralized edge computing. An edge device for implementing decentralized edge computing using a plurality of neural networks having a stacked architecture is provided, including an uncooperative unit configured to generate an initial decision using a neural network of zero-th layer that is a lowest layer of the stacked architecture, an adjacently cooperative unit configured to generate a first transmission messages and a first decision using a pair of neural networks of a first layer, and a network-wide cooperative unit configured to generate a second transmission messages and a second decision using a pair of neural networks of a second layer.
