M2M-Based Metropolitan Platform for IMS-Enabled Road Traffic Management in IoT

(IEEE Communications Magazine, 2011)

• M2M enables highly scalable direct communications among wireless enabled heterogeneous terminals, called M2M devices.

• Between M2M devices and central application servers, called M2M servers.

• The ultimate goal of these standardization activities is to leverage widespread integration of M2M devices with any existing service-level solution.

– No commonly agreed solution has been identified so far.

• In the paper here discuss the adoption of the IP Multimedia System (IMS) to M2M realms.

• Each retractable bollard hosts an M2M device that participates to the M2M device domain.

• In the network domain, we show the most important 3GPP EPS nodes and IMS components that enable the communication between M2M device and M2M server via the mobile operator network.

• In the municipality application domain, the M2M server is the service integration core component: it interacts with M2M devices via IMS.


IMS-enabled M2M-based retractable bollard management scenario

• Distributed architecture consists of three main components: the M2M server, the M2M device, and metropolitan traffic management system, called (INVENTO).

• The M2M server is the core integration component

• that glues together M2M devices with authentication functions and high-level management applications.

– Bollard authorization component (BAC) periodically queries the AAA server.

– Obtain the list of vehicles that can be admitted in each limited vehicular traffic area, and updates it to M2M devices.

– Using standard IMS PS SIP-based message exchanges managed by the IMS AS component.


• The M2M device interacts with the M2M server to receive citizen credential updates, and publish authorized accesses and possible failures (via the IMS client component).

– The authorization manager takes over user AAA activities.

– Diagnostic procedure (DP), which implements the needed support to verify the continuous operability of all available retractable bollards.

– Bollard actuator control component (BACC) executes the retractable bollard’s work. • A web-based user interface that depicts the status of operability to operators

of the municipality control center by showing all of the interesting information.

Future Internet Apps: The Next Wave of Adaptive Service-Oriented Systems?

(Proceedings of the ServiceWave 2011, LNCS 6994, 2011)

• Future Internet will be built around four major areas:

– The IoS (Internet of Services) that relates to the provision, discovery, composition, and consumption of (software) services via the Internet.

– The IoT (Internet of Things) relates to embedded systems, sensors and actuators that collect and carry information about real-world objects via their interconnection with the Internet.

– The IoC (Internet of Content) relates to the discovery, distribution, combination, and consumption of all kinds of media objects. • Carry meta-information about their content and can be accessed via the

Internet.

– NoF (Networks of the Future) relates to ubiquitous communication facilities (e.g., mobile, broadband).


• Service-oriented systems in the Future Internet, we call them FI Apps.

– The capabilities and features of FI Apps will be increasingly provided and “owned” by third parties and “shared ownership”.

• FI Apps in such a way that those applications can

– Dynamically and autonomously respond to changes in the provisioning of services, availability of things and contents

– A changes of network connectivity and end-user devices, together with changes in user expectations.

• .Adaptation will become a key capability of FI Apps/

The Transport and Logistics Scenario --- Offshore Wind Energy Plant Example

• The Future Internet Platform layer constitutes generic technology building blocks from various Future Internet areas (IoS, IoC, IoT and NoF).

• The Future Internet Application layer constitutes domain-specific technology building blocks, as well as domain-specific FI Apps.

• The Socio-Economic layer constitutes networks of people and organizations, which can benefit from the FI Apps.

Future Internet Layers and Adaptation


• Cross-Layer Adaptation

• Cross-Area Adaptation

– FI Apps to adapt not only considering the changes and resources in one specific area (e.g., service availability in the IoS), but also regarding other areas (e.g., adapting according to sensor information availability in the IoT).

• Distributed Adaptation

– employ a central entity for gathering information from distributed sources and taking the decisions.

– the central entity will only have limited access to information from the third-party service providers.

– a central entity will present classical problems like single point of failure, lack of scalability, and bottlenecks which will not be acceptable once the scale of the Future Internet.


• Context-Aware Adaptation.

• Autonomic and Human-in-the-Loop Adaptation

– This means that there will be a range of adaptation strategies from completely automated (autonomous) to interactive and manual (human-in-the loop).

• Reactive and Proactive Adaptation

– Reactively, the application is re-configured due to changes in the context or due to faults of third party services.

– Preventive adaptation is associated with the case in which an actual local failure is repaired before its consequences become visible to the end-user.

– Proactive adaptation predicts future failures and changes, and modifies the application before those changes impact.
