MQTT (Message Queue Telemetry Transport)
MQTT (Message Queue Telemetry Transport) is the simplified network protocol working atop TCP/IP, the publisher subscriber is used for message exchange between devices by the principle. The first version of the protocol was developed by doctor Andy Stanford-Clark (IBM) and Arlen Arcom in 1999 and published under a royalty big-head the license.
2017: The IoT-project for control of a livestock of pigs
In November, 2017 it became known of creation in the USA of the system of Internet of Things (IoT) allowing to monitor remotely the state of health of a livestock on pig farms. About development the CRN edition was told by developers of the experimental IoT-solution — Remote Insights and Agosto company.
The livestock industry of the USA goes through difficult times: level of a staff turnover reaches 40%, and workers of farms are forced to work overtime for a scanty payment. Besides, usually it is the share of each employee about 300 heads of pigs that does difficult a task of monitoring of health of a livestock and coefficient of a farrow.
With respect thereto in 2016 addressed the Remote Insights company developing solutions for cattle breeders producer of the veterinary medicines Zoetis and the specialist in the field of management of the pig-breeding enterprises Pipestone Systems with a request to create a system which would allow to keep track remotely of behavior of pigs and on the basis of it to judge health of a livestock. Also the partner of Google — the Agosto company specializing in IoT-solutions was connected to the project.
For accomplishment of a task in Agosto used several Google Cloud IoT Core platforms, including service at once with the open code IoT Message Broker which allows to develop IoT-applications with support of the MQTT protocol providing safe double-sided communication between objects of Internet of Things and also tools of analytics and visualization.
The developed IoT-system provides fastening of special labels to ears of pigs. Using various sensors they monitor the body temperature and movements of animals for assessment of their health and readiness for reproduction. Information from sensors is transferred to a cloud where it is analyzed then the processed data go back to the staff of pig farm. A system quickly warns if at some of individuals symptoms of a disease appear.
In February, 2018 an IoT-system will pass operational testings of livestock farms.[1]
