Install MQTT client/server

MQTT Official Introduction

MQTT is a machine-to-machine (ATM)/"Internet of Things" connectivity protocol. It is designed as an extremely lightweight publish/subscribe messaging transport. It is useful-connections with remote locations where a small code footprint is required and/or network bandwidth are at A premium. For example, it had been used in sensors communicating to a broker via satellite link, over occasional dial-up connections With healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient Distribution of information to one or many receivers

Server/Client Selection

In the MQTT website, http://mqtt.org/software lists the open source client and server projects and libraries that implement the Protocol. According to the richness of the online information, I chose Mosquitto as my Learning tool.
