Efficient and Scalable Broker Design for the Internet of Things Environments

In line with recent requirements, many institutions and organizations have started to need IoT devices. Number of used IoT devices increased because of the increasing need. These devices can collect huge amounts of data from a wide range of sensors. This increase in the number of data brings along the problem of how the data should be collected and processed. Relational databases and standard methods are insufficient for storing and processing these huge data. Therefore, in this study, a Broker that uses NoSql database to store data, indexing the short time data with Elasticsearch to increase instantaneous processing speed, can work with multiple copies thanks to virtualization, and provide powerful user interface thanks to Kibana is proposed. This proposed broker has been tested at one of our airports on low-energy bluetooth data and was able to transmit a maximum of 68,000 data per second with the determined server.
