Abstract:

In recent times there is an increase in the number of Android chat applications in the digital market. Most of these applications are based on IoT protocols like AMQP, XMPP, etc. These protocols are optimal in networks with stable connections, equipped nodes and high power devices. Through our work we propose a chat platform that is based on MQTT protocol with the aim to reduce the load on the devices with this lightweight protocol. The protocol is implemented using Eclipse MQTT server that has plugins and modules to support MQTT implementation on Android platform. Android Studio is used for the simulation and Mosquitto broker is used for publish/subscribe model implementation. The performance of the proposed model is compared with existing chat applications and the MQTT protocol features are compared with other application layer protocols. The stimulated model is tested and verified on android mobiles with version higher than 4.0. It is found that MQTT offers certain features which are better suitable in networks with constrained devices, less bandwidth capacity, or poor connection in remote locations.
