LinuxCon + CloudOpen + ContainerCon NA 2015

This presentation will introduce the day's track on IoTivity. The session will explain where the effort fits strategically among the various efforts to build standards and implementations of standards to implement the Internet of Things. It will also explain the IoTivity and OIC technical approach and why it is particularly well suited to large-scale IoT deployment.

Internet of Things (IoT) market today has many proprietary, siloed solutions that do not interoperate and as a result market is very fragmented and moves slowly. Open Interconnect Consortium (OIC), an alliance of leading industry players, was formed to define an industry-standard specification and certification program for devices to securely and reliably discover and connect across multiple OSs, platforms, and technologies, the foundational capacity to enable the Internet of Things (IoT). Iotivity is an open source reference implementation of the OIC defined specification. The Iotivity SDK can be used to build IoT applications and the framework handles discovering and communication between the devices, ensuring security and reliability. Iotivity SDK, designed to runs on a spectrum of devices from resource-constrained embedded devices to rich platforms supporting multiple communication interfaces, can be used to build IoT applications.

This talk is an introduction to Iotivity to show how developers can leverage various Iotivity features to build IoT applications. Iotivity stack include a core library that handles discovery, connectivity, and security across various layer 2/3/4 transports and services library that offers value-added functionality for IoT applications - the focus of the talk is on the core library. Iotivity allows IoT applications to model "things" as resources, akin to HTTP, and a basic set of HTTP-like primitives GET/PUT/POST/DELETE can be used to access the resources. Additionally, Iotivity resource-model supports other features to observe changes in resources or manage groups of resources securely while being agnostic of the transport. 

Enforcing security within IoT environments is challenging issue with multiple decisions to make: what kind of cryptography (shared secret or PKI) to use, does the crypto algorithms increase output payload size, are algorithms efficient enough to execute in devices with few MHz of processing power. Bootstrapping a new IoT device in your home ecosystem by maintaining a decent balance between security and usability will be key for wide adoption of IoT. This talk will cover the security architecture of Iotivity by providing an overview of provisioning, authentication/encryption and access control mechanisms employed in Iotivity.

Web services and mobile apps have significantly contributed to the popularity and adoption of mobile devices over the past decade. Bringing these services and apps into the IoT domain presents challenges in terms web service API consumption, handling parameters and managing credentials to name a few. During this talk, the author will discuss about these challenges and the current approaches to handle them. Following this, he will introduce a service layer framework in IoTivity which will enable integration of existing web services with the IoTivity stack. The details of the framework will be discussed. This will be followed by a discussion of use cases enabled by the framework.

The Iotivity primitive services accelerate your application development by providing fundamental services that are common to most of the IoT domains and application scenarios.

This talk presents an overview and introduction to the primitive services of IoTivity.
A simplified API including a resource builder eases the resource manipulation by providing a data-centric API that abstracts the basic communication mechanisms of IoTivity. Services for on-boarding and provisioning simplify the integration of new devices into the IoTivity ecosystem. A resource directory component and resource hosting capability enrich the features of intermediate IoTivity devices, which act as a link to cloud-based IoT platforms. A resource container component allows integrating legacy protocols and third-party Web APIs.

The talk will show which common services are provided and how they can be used for concrete application scenarios.
