‘Anywhere, anytime, anything connectivity’
for supporting ‘cyber-physical real world interactions’ [MSDC12]

5. Background – IoT services
5
IoT services: customized, pervasive
cyberphysical services provided
together conventional products.
Benefits
 increase operational efficiency
 boost productivity
 enhance customers loyalty
 open new markets
[PLJC14]

6. IoT services: Related work
IoT services
 well-established definition is missing
 service modeling acknowledged as fundamental
Available IoT service models
6
Developer-oriented
(metamodels,
ontology,…)
Enterprise-oriented
(Petri nets, Business
Processes,…)
descriptive approach
for high-level service
analysis
operational approach
for service verification
and simulation

7. IoT services: Related work
7
Related work analysis
 descriptive and operational models are different but
complementary
 important IoT concepts (e.g., IoT Entity, context,
policy) coarse grained modeled or neglected
Proposal: a novel IoT service modeling
paradigm which includes and improves current
operational and descriptive service models.
[MSMP11], [TMSMB12]

8. Proposal - Opportunistic IoT Service model
8
Opportunistic IoT service: distinctive features
 Context-aware
 Transient
 Co-located
 Dynamic
Opportunistic IoT service: definition
interface for entity’s functionalities that allows establishing, under specific constraints and
pre/post-conditions, a temporary and localized (in other terms, confined in the space and
in the time) usage relationship between the service provider and the service consumer(s).
The service provisioning impacts the service provider, the service consumer(s) (and, in
some case, third parties indirectly involved to the service provisioning) by modifying their
properties and/or their status.

9. Proposal - Opportunistic IoT Service model

Descriptive modeling
what service does?
how service works?
[FRRS16]

10. Proposal - Opportunistic IoT Service model
10
Operational modeling
IoT service S, IoT Entitiy E, IoT Environment Env
compliant to
[TFZT10]

11. Case study: SmartConnectivity IoT service
SmartAGV (Automatic Guided Vehicle) performs temporary networking (opportunistic SmartConnectivity
service) to overcome node failures and enhance the connectivity of a SmartWorkshop (comprising and
clustered in Production, Assembly, Boxing and Controlling Areas) [DLFY16]

12. Conclusion and future work
12
• Problem: limitations affecting IoT service modeling hinder the subsequent
phases of service automatic verification, execution and simulation.
 Preliminary contributions: definition of (i) Opportunistic IoT service
definition 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.
