Descriptive and Operational models are different but complementary
Important IoT concepts (e.g., IoT Entity, Context) coarse grained
modeled or neglected, considering IoT services like Web services
A novel IoT service modeling paradigm which includes and improves
current operational and descriptive service models is required. 7

Operational modeling
Considering that IoT Entities and Service interactions are typically (asynchronously) event-driven
and time-dependent, IoT systems may be formally modelled as Discrete Event Systems (DESs) and
represented, for example, through finite state automata.

15. Use Cases
15
Smart City: a large-scale scenario, highly dynamic and with a variety of potential different
IoT Entities and services.
Smart Workshop: a medium-scale, homogeneous scenario with a limited number of IoT Entities,
specific functionalities but strict requirements.
The proposed approach supports scenarios featured by
different scales, purposes, and requirements.
16. Smart City Use Case: Crowd Safety Service
16
Crows Safety Service considers a mass public event, such as the Vienna marathon, and aims at
(i) alerting people located nearby overcrowded zones;
(ii) proposing alternative paths according to the user’s preferences/constraints.

Crows Safety Service considers a mass public event, such as the Vienna marathon, and aims at
(i) Alerting people located nearby overcrowded zones;
(ii) Proposing alternative paths according to the user’s preferences/constraints.
Crowd Safety Service exposes the four aforementioned opportunistic properties of:
1. Dynamicity, since it is activated only if a zone’s density level exceeds a threshold continuously for
a certain amount of time;
2. Co-located, since it exploits multiple SOs at the same time for contemporary serving multiple
citizens located nearby the overcrowded zones;
3. Transient, since it lasts only for an emergency situation and until the citizen is near an
overcrowded zone;
4. Context-aware, since it considers athletes and audience positions and environmental elements
(e.g., a bridge) for determining density and risk levels, as well as citizens positions and their
preferences for providing alerts and customized hints.

Smart Workshop Use Case: Smart Connectivity Service
Smart Connectivity Service performs temporary networking to overcome a node failure within a
clustered workshop area, and aims at:
(i) providing a temporary intra-cluster networking activity to prevent network fragmentation;
(ii) providing a temporary inter-cluster networking activity to prevent network paralysis.

24. Conclusion and future work
24
Problem: limitations affecting IoT service modelling hinder the subsequent
phases of service automatic verification, execution and simulation.
Preliminary contributions: definition of (i) Opportunistic IoT Service
properties and (ii) a full-fledged approach jointly exploiting descriptive
(metamodel-based) and operational (DES-based) IoT Service models.
Future work: implementation of descriptive and operational IoT Service
models within an integrated framework for performing service automatic
verification, execution and simulation.
