Data Storage and Sharing for Mobile Devices in Multi-region Edge Networks
Aug 2020
The edge computing paradigm has been recently introduced with the aim of bringing cloud services closer to end- users, by providing an intermediate layer between devices and the actual cloud infrastructure, resulting in faster response times. In this paper, we propose a framework that leverages stationary nodes within the edge infrastructure to provide a persistent publish/subscribe system to a set of mobile devices, distributed across multiple network regions. We combine device-to-device and device-to-edge interactions with the goal of optimizing access to relevant data and allowing such data to be available to all users, hence creating a persistent and global data storage and dissemination network. Our experimental results show adequate response times for interactive usage and low energy consumption. We also evaluate our system against a cloud solution and verify that our proposal yields considerable latency speedups.
