MQTT-SN GATEWAY INTEGRATION WITH AWS CLOUD MQTT SERVER AND IOT APPLICATION

Current wireless sensor devices are facing a lot of issues to integrate with the global internet communication networks due to incompatible Application messaging protocols. Currently various heterogeneous application messaging protocols are available like HTTP, MQTT, COAP, DDS, AMQP. Each of this application messaging protocols are designed and implemented as per different application requirements considering the computational resources and available communication bandwidth. These protocols are not suitable for constrained sensor devices due to limitation of computational power and bandwidth. MQTT protocol is designed and implemented for Machine to Machine communication, but still not suitable for low power sensor devices due to complex TCP transport protocol used. More Efficient MQTT-SN protocol is (Message Queue Telemetry Transport-Sensor Network) proposed for sensor devices considering the wireless sensor network characteristics, power constraint and bandwidth limitations. MQTT-SN messages are transported using less over head UDP Transport Protocol. In this paper we are provided the procedure how the MQTT-SN Gateway Integration with Industry standard AWS MQTT-Server and End to End Sensor Data Transmission from Sensor Device to the IOT Application through MQTT-SN Gateway and AWS(Amazon Web Services) MQTT Serve
