MESDD: A Distributed Geofence-Based Discovery Method for the Computin...

Service discovery is a vital process that enables low latency provisioning of Internet of Things (IoT) applications across the computing continuum. Unfortunately, it becomes increasingly difficult to identify a proper service within strict time constraints due to the high heterogeneity of the computing continuum. Moreover, the plethora of network technologies and protocols commonly used by IoT applications further hinders service discovery. To address these issues, we introduce a novel Mobile Edge Service Discovery using the DNS (MESDD) algorithm, which uses a so-called Intermediate Discovery Code to identify suitable service instances. MESDD uses geofences for fine-grained service segmentation based on a naming scheme that identifies users’ locations across the computing continuum. We deployed a real-life distributed computing continuum testbed and compared MESDD with three related methods, outperformed by 60 % after eight update iterations.
