IPSO Alliance

Enabling IoT Devices’ Hardware and Software Interoperability

What is the IPSO

Alliance?The IPSO Alliance is a global forum comprising a diverse international membership focused on enabling IoT devices to communicate, understand and trust each other with global interoperability based on open standards.

IPSO Alliance membership is open to all organizations supporting an IP-based approach to connecting smart objects and interested in defining the future of the Internet of Things.

The Importance of Interoperability

4

IoT Systems: heterogeneous, large-scale, distributed systems with multi-

vendor building-blocks

We need Interoperability to build systems, create systems of

systems, to keep cost low, to reduce risk, to spur innovation,…

IoT

The challenge

• An aircraft jet engine is built with

25,000 parts

• A passenger car has 30,000

• A wind turbine has 8,000

• There are >10,000 types of medical

devices

…all of which are from hundreds of

manufacturers

• Why Semantics?• The 2015 McKinsey report that said 40% of the additional

value to IoT is interoperability • Interoperability starts with the data• The value add exists when data coming from any origin can

be shared and used by everybody• The IPSO smart object definition is gaining traction:

•OMA•Bluetooth (BIPSO)•STMicroelectronics • IoTerop (and its smart city initiatives)•… and more

• Why Protocol?

• There are too many IP standards to choose from currently

• There is a need to evaluate performance; some perform

better in certain markets and others better elsewhere

• The Protocol Working Group is tasked with answering how

to use Internet Protocol(s)

• With the success of IPSO Smart Object v1, IPSO is now working on

Smart Object v2 which is specifically addressing the issues with:

• Stringent Object/Resource ID standardization processes and activities which are

becoming a barrier in describing “things” dynamically

• Compile / development time binding of Objects/Resources into code which

makes the adoption and continuous improvements to “things” rather difficult

• Interoperability can only be achieved by the SDOs interoperability• OMA is a very important IPSO partner

Reasons for this presentation

IPSO Smart Object

Model V1.0

• IPSO Data Model V1.0• Our surroundings can be expressed as a model of Objects & Resources

• Break large components into atomic components, e.g. relays, temperature sensors,

digital input / output, etc.

• Objects and Resources are standardized one by one, and registered with OMNA

Object Validation

• Anybody can use composition to create new Objects from the existing

ones. You need to validate them before submitting new ones. You can use

'xmllint' to validate against the LWM2M Schema.

Welcome to the public IPSO Repository

10

# Run xmllint against one or multiple Objects

$ xmllint --noout --schema LWM2M.xsd example.xml

# The output should be:

$ example.xml validates

• http://www.openmobilealliance.org/wp/OMNA/LwM2M/LwM2MRegistry.html

OMNA can provide you with an unique Object or/and Resource Identifier:

(Object ID) or (ResourceID).

To register a new (Ojbect ID) or (Resource ID).

OMA has developed an editor for creating LwM2M Objects & Resources.

•The LwM2M Editor can be accessed here: Editor.

•The XML schema used by the LwM2M Editor can be found here: Schema.

IPSO V1.0 Data Model

Challenges

• The definition and registration process of objects and resources doesn’t

escalate very well:• All Objects / Resources and any permutations and variations thereof must be predefined á

priori

• Huge standardization effort is required to define Objects/Resources for components in

each vertical sector: industrial, smart cities, transport, etc• It requires companies from different sectors to agree what and how to standardize sensor

properties.

• Registration, validation and verification effort cannot be underestimated if the aim is to reach out to

billion of devices.

Challenges of this Data Model

Logistic and Operational Challenge

• Since all the bindings are done at development/compile time, any new

“thing”, changes to an existing “thing”, or any new variations thereof

require redevelopment of drivers, testing, and firmware update

• There’s absolutely no way for a new “thing” to automatically work without

any changes to the client framework

Technical Challenge

ClientPlatform

• Reusable Object IDs and Resource IDs.

• Transport protocol and encoding data format independent.

• Easy to build your own Objects and add to repo.

• Easy to get feedback.

• Sufficient for current use cases.

• Trivial to integrate with LWM2M.

• Tested.

Interoperability

Any actual example system/implementation to demonstrate how IPSO plays so well for interoperability?

18

• The current paradigm doesn’t scale well in a market of billion of “things” –

including virtual - and millions of variations to the same “things”:

• Standardization & registration effort is a daunting task

• Development/Compile time integration is an impediment to interoperability

Limitations of the IPSO Smart Object model V1.0

Next Steps

• IPSO is working on a Node Meta Model• A Model that defines how things should be defined• “Things” do not need to be defined a priori and promotes runtime binding• Proof of Concept is already completed and working in the real world

• Proof of Concept for integration with LWM2M already completed (ST Micro)

• Synergy with IPSO• IPSO deals only with the model• The model is protocol, security, bootstrap, and commissioning agnostic –

a major synergy with OMA and LWM2M• No framework available – Should we work with the Eclipse Foundation?

• Possible impact in the evolution of LwM2M• This is for OMA to assess based on the information of the new model.

Next Steps

• No Web Linking! (but easy to add)

• LWM2M Object Versioning.

• Not suited for complex hypermedia interactions.

• Could have a richer language to represent IPSO Objects instead

of XML.

• Missing a lot of IETF CoRE-Link concepts: recource type "rt",

"cf", etc.

• Also URI 3303/0/5700 (no decoupling)
