Motivation

Clear trend towards mobile-phone based interactions with products and objects, many applications have been (and are being) demonstrated.

Lack of applications and toolkits based on standard architectures.

The MobileIoT toolkit proposes the « standard » Internet of Things (EPC network) in a box.

Slide 4 / 24

Approach

Started in frame of the Mobile to Internet of Things Nokia/ETH project.

Basic description:– Creating a toolkit for rapid application development for the mobile

phone platform, which connects to the EPC Network infrastructure.

Approach:– Providing a set of tools to:

Access and use various Auto-ID technologies (barcodes, NFC, UHF EPC).

Access and use the EPC Network backend software (e.g Fosstrak (ex Accada) or SAP AII).

Implementation: Leveraging the Electronic Product Code Network.

EPC number uniquely identifies an object.

Reader Protocol ensures a common read protocol for all tags.

The EPCIS is the information server:

– Records RFID events (traces).

EPC Network as tracking and tracing infrastructure based on RFID technology.

Server Tools: Business Connectors

Product Code Translation:– Tools based on the Tag Data Translation (TDT) specification and

Fosstrak’s (ex. Accada) implementation.

– Given an standard number in any form the EPC class will use the TDT to create a valid and polymorph EPC identifier object.

Slide 18 / 24

Server Tools: Business Connectors

EPC Information Service Connectors:– Contains the mobile connectors to the IoT backend (Fosstrak

EPCIS, SAP Auto-ID infrastructures).

– These connectors abstract selected operations on IoT backend which: Enables to query the EPCIS using REST.

Hides the complexity of a particular IoT backend (no need to know the EPCglobal standards).

– The Accada connector was implemented.

Future Work and Extensions

Created a Toolkit, aggregating several other toolkits and helping the programmer in rapidly prototyping standard mobile to IoT applications.

Planned extensions:– Extended REST support for the EPCIS.

– Integrate the NFC contactless toolkit.

– Create a connector to the SAP Auto-ID Infrastructure (SAP AII).

And many nice possible extensions:– J2ME Web Services Specification (JSR 172) and comply with JSR 257.

– Integration of an ONS query system.

– Develop methods to automate the run-time selection of the best Auto-ID technique to use (UniversalReader).

– Etc.

To be licensed as Open Source soon.
