Every year global cities swell in size. Modernization in techniques helps create sustainable cities for all. Cloud infrastructure providers strive to offer the highest level of availability across the infrastructure stack with the help of Fog Computing (FC) that was invented to deal with IoT interacting with wireless sensor networks (WSN) to enhance services. For intelligent devices to communicate efficiently, the Mobile ad-hoc network (MANET) in IoT is required. Intelligent devices that are connected together through the aforementioned networks may suffer from sudden errors in data storage and transfer thus the need for zero touch networks where devices can heal and adjust themselves to form autonomous networks based on data collected from different integrated network devices. In this work we aim to provide an overview of recent research works that combine FC, IoT and MANET technologies integrated together to build up sustainable cities. We illustrate works of three important applications that affect human daily life. While zero touch technologies are still in their early stages, we set a study of the latest information related to zero touch technologies and how AI supported by machine learning and data analytics constitutes a key enabler to fully autonomous future generation cities.
