CREATING A BRIDGE OF BROKERS FOR MESSAGE QUEUE TELEMETRY TRANSPORT (MQTT) PROTOCOL

As we all know that, all soft computing devices are able to connect with each other through internet. This is calling as internet of things (IoT) [4],[8]. IoT uses different protocols to exchange information among various devices. Different protocols are available i.e., constrained application protocol (CoAP), message queue telemetry transport (MQTT), Advanced message queuing protocol (AMQP) and so on. These protocols are intended for constrained devices i.e., devices with low RAM size and processor. MQTT is a light weight protocol with publish/subscribe communication model. MQTT uses a broker to provide communication among devices which are subscribed to the broker. Various brokers are available in the market like mosquito, RabbitMQ and so on. These brokers allow to receive and send information, only the devices which have subscribed to a particular broker. The devices which have subscribed to other broker are unable establish communication. If devices would like make communication with the devices connected with other brokers is required to make a group or bridge of brokers.
