However…
The market is fragmented– Hardware, software, protocols…
all different, independent– Lack of integration…
between devices, to enterprise systems
M2M development is complex– Many different skills required…
Hardware, Embedded, IT network, Telecom, web– No common architectural guidelines
Current options are closed– Monolithic solutions…
device specific, app specific, market specific– Proprietary SDKs, protocols, potential vendor lock-in

MQTT in a Nutshell
■ MQTT == MQ Telemetry Transport■ In a nutshell
“A light weight event and message oriented protocol allowing devices to asynchronously communicate efficiently across constrained networks to remote systems”
MQTT - Publish Subscribe Messaging
A Publish Subscribe messaging protocol allowing a message to be published once and multiple consumers (applications / devices) to receive the message providing decoupling between the producer and consumer(s)
A producer sends (publishes) a message (publication) on a topic (subject)A consumer subscribes (makes a subscription) for messages on a topic (subject)
A message server / broker matches publications to subscriptions • If no matches the message is discarded• If one or more matches the message is delivered to each matching subscriber/consumer
Benefits of MQTT verses HTTP■ Push delivery of messages / data / events
– MQTT – low latency push delivery of messages from client to server and server to client• Helps bring an event oriented architecture to the web
– HTTP – push from client to server but poll from server to client• Efficient use of network
– For an M2M project the number of bytes with MQTT was 137130 bytes per device per month with HTTP the number of bytes was 801000 bytes per device per month
• Reliable delivery over fragile network– MQTT will deliver message to QOS even across connection breaks
• Decoupling and publish subscribe – one to many delivery

M3DA Layered ArchitectureApplication Layer – M3DA::Message
– Specify access to the tree-oriented data model
Transport Layer – M3DA::Envelope– Enables authentication, encryption,
compression, …
Serialization Layer – Bysant– Provides an efficient binary serialization
based on contextual information
