AllJoyn FrameworkDrawbacks

• Limited to Local Area Networks only Sol: Cloud i.e Microsoft Azure

• No Data Storage embedded Sol: Add extension i.e AllJoyn Lambda

Summary

• Internet of Things(IoT) • What is Internet of Things? • Which part can IoT apply for?

• AllJoyn Framework • What is AllJoyn? • What does each AllJoyn application have? • How AllJoyn devices communication with? • What the drawbacks of the AllJoyn?

Security?
