Abstract: The Internet of Things (IoT) consists of distributed entities that federate to implement use cases. Driven by its applications, distributed IoT services federate dynamically to deliver complex functionality.A fundamental requirement for service composition is discovery. The IoT requires a semantically-rich, dynamically extensible, low complexity service discovery mechanism. Existing mechanisms fail in delivering this functionality.We present a distributed modular directory of service properties. It can be extended at runtime. Combined our so-called search provider directories form an IoT ontology. With the novel modularization, our simple directories mash-up to a complex ontology. We introduce a query federation mechanism. Based on first-order logic it enables mapping complex semantic queries on the simple search providers. We evaluate our prototype regarding latency and usability.

QoS-Aware Service Discovery and Selection Management for Cloud-Edge Computing Using a Hybrid Meta-Heuristic Algorithm in IoT
Ronghan Wang,Junwei Lu +1 more
TL;DR: In this article, a QoS-aware cloud-edge service discovery and selection model in IoT environment is presented, which is evaluated based on a hybrid multi-objective meta-heuristic algorithm based on Grey Wolf Optimizer and a Genetic Algorithm (GWO-GA) for evaluating QoS factors as nonfunctional properties.

Giving IoT Services an Identity and Changeable Attributes
Marc-Oliver Pahl,Lorenzo Donini +1 more
- 08 Apr 2019
TL;DR: This work gives IoT services secure identities and attributes using site-local X.509v3 certificates with short lifetimes, and shows how service attributes can securely be changed at runtime, which enables enforcing security policies even on distributed, loosely coupled IoT nodes.

A relational model of data for large shared data banks
TL;DR: In this article, a model based on n-ary relations, a normal form for data base relations, and the concept of a universal data sublanguage are introduced, and certain operations on relations are discussed and applied to the problems of redundancy and consistency in the user's model.
