Abstract:

Internet of Things has been getting more and more attention and found numerous practical applications. Especially important in this context are performance, security and ability to cope with failures. Especially crucial is to find good trade-off between these. In this article we present results of practical tests with multiple clients representing sensors sending notifications to an IoT middleware – DeviceHive. We investigate performance under different loads by various numbers of IoT clients and show how various strengths of the hash algorithm affect the performance measured by the number of client requests handled within a predefined time frame.
