Abstract

Internet of Things (IoT) is the machine-to-machine or machine to application communication concept which has the vision that billion of sensors, actuators, and many daily devices could be connected to the internet. Message Queue Telemetry Transport (MQTT) is one of the protocol included in Internet of Things which is useful to save power and reduce the size of packet data messaging. Therefore, it is important to study the ability of modern IoT systems to handle high rates of data updates coming from devices. The upcoming thing in the future is about storage media to handle the IoT data, such as a database system to store the data. A flexible database which could handle the data from the IoT device is required. The writer in this work will evaluated the performance of Not Only SQL (NoSQL) MongoDB Database towards MQTT Protocol. In this work, writer use the parameter for the performance testing is the Load Testing. The process practice for the MQTT Protocol as a sensor data transmission media uses NodeMCU microcontroller with the publish and subscribe method. Load Testing method was choosen as a technique to test the relation between the execution time of MongoDB to store the data of the sensor from MQTT protocol. From this work, claimed that NodeMCU could be configurated with MQTT Protocol, with a 75% accuracy of success for connection within the range from 4 meter to 20 meter. From this work we also got that the execution time for MongoDB to store 50 to 1500 data without the database being configured is less than 0.5 Second, and the execution time for MongoDB to store 50 to 1500 data if the database was already set needs less than 0.2 second to store.

Abstract

The growth of computer network technology has an impact on the high demand for network performance and increasingly control network complexity. Network performance can be affected by network management, one of which is routing protocol. On a conventional network, routing protocol configuration is inflexible, inefficient and needs to configure each network device. One of the solution for this problem is SDN (Software defined network). The programmable SDN control plane make it possible to implement routing application. This research uses two kind of shortest path algorithm those are Floyd-Warshall algorithm and Johnson algorithm. Both algorithms are implemented in ryu controller and mininet as SDN network simulator. Packet loss dan delay testing has no significant difference. In the packet loss testing Floyd-Warshall has an average of 2,33% compared to Johnson with an average of 2,48%. While the result of delay testing, the average delay of Floyd-Warshall is 4,08 ms compared to Johnson with an average of 4,02 ms. Convergence time testing, Johnson is faster when the number of switches 6 and 10. While Floyd-Warshall is better when the number of switches 14. In cpu usage testing, Johnson algorithm consumes more resources with an average of 23,84% compared to Floyd-Warshall algorithm with an average of 21,78%. While the result of memory usage of both algorithm equally consume 1,3% of memory.
