In this paper we make the case for IoT edge offloading, which strives to exploit the resources on edge computing devices by offloading fine-grained computation tasks from the cloud closer to the users and data generators (i.e., IoT devices). The key motive is to enhance performance, security and privacy for IoT services. Our proposal bridges the gap between cloud computing and IoT by applying a divide and conquer approach over the multi-level (cloud, edge and IoT) information pipeline. To validate the design of IoT edge offloading, we developed a unikernel-based prototype and evaluated the system under various hardware and network conditions. Our experimentation has shown promising results and revealed the limitation of existing IoT hardware and virtualization platforms, shedding light on future research of edge computing and IoT.

The Internet of Things (IoT) is slowly, but steadily, changing the way we interact with our surrounding. Smart cities, smart environments, smart buildings are just a few macroscopic examples of how smart ecosystems are increasingly involved in our daily life, each one offering a different set of information. This information's decentralization and scattering can be exploited, optimizing mobile nodes on-demand information retrieval process. We propose an approach focused on defining competence domains in smart systems where the responsibility of providing a specific information to a mobile node is defined by spatial constraints. By exploiting the interplay and duality of Cloud Computing and Fog Computing we introduce an approach to exploit data spatial allocation in smart systems to optimize mobile nodes information retrieval.
