DOI: 10.1109/twc.2023.3331263
Abstract: Despite its vital role in intelligent IoT networks, distributed computing was not studied well in wireless networks. Notably, the distortions introduced by wireless channels and noise can significantly undermine the accuracy of distributed computations. Unfortunately,… read more here.
