The WSN network is increasingly gaining attention because of the potential for new and attractive solutions in the field of industrial automation, asset processing, environmental preparation and others. But there are some problems in building the WSN network. Sensor nodes must manage small, cost-effective, low-resource, node sensors must be managed properly with WSN networks Managing WSN networks, can be done by controlling sensor nodes such as giving commands to data transmission activities and monitoring to determine the condition of sensor nodes. The MQTT protocol with the type of publishing / subscription communication is designed with characteristics similar to the characteristics of the WSN network, which are simple, lightweight, energy efficient and easy to implement.In this study, a server will be implemented that can control and monitor the sensors of the WSN network node using the MQTT protocol. Then RTT parameters are used, Qo parameters include Delay, Jitter, Throughput, Packet Loss and sensor node memory condition parameters when using the MQTT protocol. The RTT and QoS scenarios use variations in data size of 16,32,48,64,80 and 96 bytes. Monitoring memory nodes, performing for 1 minute with a total of 30 data transmissions. The RTT parameter testing results are quite stable. QoS testing is very good with stable delay, jitter, increasing throughput, and 0% of data lost when packet loss testing. The Test Memory node sensor, shows erratic results.
On the effects of the packet size distribution on the packet loss process
