MQTT - MQ Telemetry Transport for Message QueueingPeter R. Egli
Description of message queueing (MQ) protocol for the transport of telemetry data (MQTT - MQ Telemetry Transport).
MQTT is a protocol designed to fit the needs of Internet of Things scenarios. It is lightweight and efficient, but still affords all the features required for reliable messaging between wireless sensor / actor nodes and applications. MQTT decouples producer and consumer of data (sensors, actors and applications) through message brokers with publish / subscribe message queues called topics. MQTT supports different levels of quality of service thus providing the flexibility to adapt to the different needs of applications.
Further features like will and retain messages make MQTT well suited for sensor network scenarios as well as for lightweight enterprise messaging applications.
Open source implementations like Eclipse paho provide ample code for integrating MQTT in your own applications.
Internet of Things requires communication to devices that are either actuators or sensors. Each actuator and sensor has an identity. Each actuator and sensor may be either directly connected to the world wide web or indirectly connected via a type of gateway.
Communication to these devices needs to be reliable. Therefore each device may implement their most suitable communication protocol.

How do Things talk? IoT Application Protocols 101Christian Götz
Analysts predict that in 2020 50 billion devices are connected to the internet. Together with the fact that more and more of these "things" are connected over the cellular network, new challenges are introduced to the communication of Internet of Things (IoT) and machine-to-machine (M2M) scenarios. There are a lot of protocols which claim to be ideal for these use cases, for example MQTT and COAP. In this talk you will get an overview of commonly used protocols and their underlying architectural styles. We will also look at advantages/disadvantages, use cases and the eco-system around them for Java developers.

M2M Protocols for Constrained Environments in the Context of IoT: A Compariso...Edielson P. Frigieri
The Internet of Things movement opens new possibilities for services and business along with new technological challenges, such as power efficiency, operation in constrained environments, security, and privacy. With the expectation of a high amount of devices connected in this Future Internet, scalability is also assumed to be a challenge. To address these limitations, several protocols are being proposed. In this paper, two of them, MQTT and COAP, are presented and qualitatively compared, summarizing their main features and limitations, highlighting the best scenarios where each approach is more suitable.

IAB-5039 : MQTT: A Protocol for the Internet of Things (InterConnect 2015)PeterNiblett
MQTT is a simple, event-driven messaging protocol designed for use in Internet of Things and mobile applications. It's implemented in IBM MessageSight and MQ, and it is the protocol used by the IBM Internet of Things Foundation. You will hear it mentioned in several of the talks at this conference; and, as it recently became an official standard and is being used more and more in the world at large, you may have heard about it in the press as well. Come along to this unashamedly technical session to learn about what the protocol actually does, and how to program to it in Java, C or JavaScript.

Iot Conference Berlin M2M,IoT, device management: one protocol to rule them all?Julien Vermillard
M2M/IoT is rapidly growing and since its early days different “standard” protocols have emerged (e.g. OMA-DM, TR-069, MQTT, …) or are emerging (e.g. CoAP or Lightweight M2M). Understanding which protocol to use for which application can be intimidating, therefore we propose to give an overview of these protocols to help you understand their goals and characteristics. We’ll present common M2M use cases and why they usually require more than just one protocol ; we will also see whether CoAP associated with Lightweight M2M allows to forge “one protocol to rule them all”.

NTNU Tech Talks : Smartening up a Pi Zero Security Camera with Amazon Web Ser...Mark West
A key advantage of the IoT is that it enables you to expand the potential of constrained devices by giving them access to the computational power of The Cloud.
In this session I’ll show you how I transformed a lowly Raspberry Pi Zero webcam into a smart security camera (with motion detection, threat detection and alert notifications) by combining open source software with cloud based image analysis.
Attendees can expect a short introduction on how to set up their own Raspberry Pi Zero webcam, a comparison of some of the image analysis API’s currently available, and finally a demonstration of how I used Node.js and a range of cloud based API’s (including Amazon's Rekognition, Lambda and Step Functions) to help my smart security camera distinguish between an unwanted guest and the neighbour’s cat.

What is the application protocol for IoT.pdfashumasih3
The application protocols of IoT enable network entities to identify and interact with each other. The application protocols form the functional blocks of IoT. It determines the application's complexity. the logical design of IoT system is the actual design of the configuration and assembly of its components (computers, sensors, and actuators).
How does the Facebook Messenger app achieve phone-to-phone messaging latency in the order of milliseconds instead of seconds? Answer: It uses the MQTT protocol. And so can you.
In this session we look at the MQTT protocol and explain why it in many cases is a much better choice than HTTP or push notification for your mobile communication needs. Using the MQTT protocol your mobile app can achieve secure, reliable two-way communication without killing battery or wasting precious bandwidth. And it’s open source!
A reference architecture for the internet of thingsCharles Gibbons
A reference architecture for the internet of things: including Devices, Protocols, massively Distributed Service Layer, Business Support Systems, Channels, Device Management and Identity Management.
Internet of Things requires communication to devices that are either actuators or sensors. Each actuator and sensor has an identity. Each actuator and sensor may be either directly connected to the world wide web or indirectly connected via a type of gateway.
Communication to these devices needs to be reliable. Therefore each device may implement their most suitable communication protocol.

Protocols
There are many different usable protocols for communication with M2M
devices for the Internet of Things
Specific protocols are more appropriate for different devices (e.g. memory &
power profiles)
Specific protocols are more appropriate for different communication needs
(e.g. State Transfer Model & Event Based Model)
The most usable protocols are:
HTTP/HTTPS & WebSockets (and RESTful approaches on those)
MQTT 3.1 / 3.1.1
MQTT -SN
Constrained Application Protocol (CoAP)
XMPP

Intro: Protocols & Devices
•Devices are independent &
distributed
•Communications involve
complex Networking and

HTTP / HTTPS & WebSockets (and
RESTful approaches)
Small devices (8-bit controllers) can only partially support the protocol (e.g.
POST / GET)
HTTP Polling inefficient & costly in terms of network traffic & power usage.
Use HTTP WebSocket: allows a two-way connection that acts as a socket
channel (similar to a pure TCP channel) between the server and client. Once
that has been established, it is up to the system to choose an ongoing
protocol to tunnel over the connection.
Can use MQTT over WebSockets (firewall-friendly) & can support pure
browser/JavaScript clients using the same protocol.
Note: WebSockets would utilise most of the available space on a typical 8-bit
device so more suitable protocol for 32-bit devices

MQTT: https://www.oasis-open.org/committees/mqtt/
MQTT is a publish/subscribe messaging protocol designed for lightweight
M2M communications. Originally developed by IBM & now open standard.
MQTT has a client/server model, where every sensor is a client and connects
to a server, known as a broker, over TCP.
MQTT is message oriented. Every message is a discrete chunk of data,
opaque to the broker.
Every message is published to an address, known as a topic. Clients may
subscribe to multiple topics. Every client subscribed to a topic receives every
message published to the topic.
MQTT supports three quality of service levels, “Fire and forget”, “delivered
at least once” and “delivered exactly once”.
6. +
MQTT-SN: http://mqtt.org
MQTT-SN is a variation of the main protocol aimed at embedded devices on
non-TCP/IP networks, such as Zigbee
Even though MQTT is designed to be lightweight, it has two drawbacks for
very constrained devices:
1. Every MQTT client must support TCP and will typically hold a connection open to
the broker at all times. For some environments where packet loss is high or
computing resources are scarce, this is a problem.
2. MQTT topic names are often long strings which make them impractical for
802.15.4.
Both of these shortcomings are addressed by the MQTT-SN protocol, which
defines a UDP mapping of MQTT and adds broker support for indexing topic
names.
7. +
COAP: http://tools.ietf.org/html/draft-ietf-core-coap-18
CoAP is designed for the needs of constrained devices. CoAP packets are
much smaller than HTTP TCP flows. Packets are simple to generate and can
be parsed in place without consuming extra RAM in constrained devices.
CoAP runs over UDP, not TCP. Clients and servers communicate through
connectionless datagrams. Retries and reordering are implemented in the
application stack. CoAP allows UDP broadcast and multicast to be used for
addressing.
CoAP follows a client/server model. Clients make requests to servers, servers
send back responses. Clients may GET, PUT, POST and DELETE resources.
CoAP is designed to interoperate with HTTP and the RESTful web at large
through simple proxies.
Requests and response messages may be marked as “confirmable” or
“nonconfirmable”.
8. +
MQTT & CoAP Comparison
Both protocols have pros and cons, choosing the right one depends on
your application & device
MQTT is a many-to-many communication
protocol for passing messages between
multiple clients through a central broker.
Suited to messaging for live data.
MQTT clients make a long-lived outgoing
TCP connection to a broker.
MQTT provides no support for labelling
messages with types or other metadata to
help clients understand it. MQTT messages
can be used for any purpose, but all clients
must know the message formats up-front to
allow communication.
CoAP is a one-to-one protocol for
transferring state information between
client and server.
Suited to a state transfer model, not purely
event based.
CoAP clients and servers both send and
receive UDP packets. In NAT environments,
tunnelling or port forwarding can be used to
allow CoAP, or devices may first initiate a
connection to the head-end as in LWM2M
CoAP provides inbuilt support for content
negotiation and discovery allowing devices
to probe each other to find ways of
exchanging data.
9. +
XMPP: http://wiki.xmpp.org/web/Tech_pages/IoT_systems
Extensible Messaging and Presence Protocol (XMPP) is an open
communications protocol for message oriented middleware based on XML
Originally named Jabber
Text based
XMPP features such as federation across domains, publish/subscribe,
authentication and its security even for mobile endpoints are being used to
implement IoT
XMPP works over TCP or via HTTP using a WebSocket implementation
Custom functionality can be built on top of XMPP to provide M2M
communications and Identity Services
