Introduction to AllSeen Alliance


- Crucial need to develop communication platform merging majority of smart devices and so providing desired interoperability

- Provide a special AllJoyn routing node (gateway agent) for secure and manageable connections with external network devices and services in IoT domain

Introduction – AllJoyn application framework and Our focus

AllSeen Alliance vision for Internet of Things using the

AllJoyn framework

• we focus on the remote control system for light sources• the extension for AllJoyn Framework suitable for various

communication technologies• we expand our vision of control system on remote management,

using cloud entity• The additional requirements to provide a comprehensive package for

IoT: • type of communication (one-directional, bi-directional)• communication protocols (on application and transport layer)• security (encrypted communication) should be implemented

• IoT protocols : • Constrained Application Protocol (CoAP)• Message Queue Telemetry Transport (MQTT)• Data Distribution Service (DDS)

• Two cornerstones enabling the development of applications : • OSGi framework • AllJoyn framework

Frameworks and protocols


Frameworks and protocols categorized by communication TCP/IP layers Communication protocols supported by the studied frameworks

AllSeen Alliance offers the support of wide variety of communication protocols and it's also modular for future changes and improvements

Architecture of AllJoyn framework


• Apps and Routers:• App uses its own Router• Multiple Apps on the same device use one Router• App uses a Router on a different device

• Software architecture• Standard core (Android, iOS or Linux)• Thin core (Arduino, Intel Edison, ThreadX)

AllJoyn Gateway Agent


• Remote access and management • Security and data privacy• Interoperability• Support for open standards

Key features the purpose of gateway agent in AllJoyn architecture

• The connector for communication between internal distributed communication bus (DBus) and remote devices located outside the home (local) network was developed

• Gateway Agent was defined as a special AllJoyn routing node for secure and manageable connections with external network devices and services

• Our own instance of Gateway Agent created –source codes are available on GitHub

The new message format for our application to meet the message length is restricted to 140 characters wascreated

Created the new message format for our application:• AllJoyn - determinates whether it is an incoming

command to get status (info) of bulb(s) (AllJoynLS) or command to change parameters (AllJoynLC)

• lampID - defines the bulb ID (uint32 t) • onOff - bulb status (i) On (1), (ii) Off (0) • hue - hue definition in range 0 to 360 • saturation - bulb saturation in percents• colorTemp - light temperature defined in Kelvin in

range 2700 to 5500.• brightness - key parameter of brightness, defined

in percents

We used one of the most popular social application Twitter

Lessons learned and final thoughts


• Number of challenges addressed, mostly due to the fact, that structure (modules and classes) of AllJoyn framework was changing frequently (development procedure on monthly basis)

• Our developed extension comprises all mentioned parts and enables possibility to build our created Gateway Agent connector with libraries provided as a part of AllJoyn framework

• To prove the functionality of developed connector software tool that simulates a lamp running the AllSeen Alliance’s Open Source AllJoyn Lighting Service Framework was created

• New message format for sending commands ”tweets” implemented

• We believe our created extension of Gateway Agent within the AllJoyn framework can be used (and modified) by community members

Thank you for Attention!
