TL;DR: Wang et al. as discussed by the authors proposed a novel edge FL architecture based on edge devices in mesh network architecture; next, they exploited the mesh networking features to address the problem of possible internal attacks from edge devices and design a Dynamic Local Differential Privacy (DLDP) algorithm; then, according to the communication characteristics of mesh network, they design Edge-FedAvg algorithm to reduce the communication cost; finally, to enhance the response to untrusted center servers, embed watermark in the model to further enhance the privacy protection capability.
