TCEP: Transitions in operator placement to adapt to dynamic network environments

Distributed Complex Event Processing (DCEP) is a commonly used paradigm to detect and act on situational changes of many applications, including the Internet Things (IoT). DCEP achieves this using simple specification analytical tasks data streams called operators their distributed execution set infrastructure. The adaptivity dynamics IoT applications essential very challenging in face changing demands concerning Quality Service. In our previous work, we addressed issue by enabling transitions, which allow for adaptive use multiple operator placement mechanisms. article, extend transition methodology optimizing costs analyzing behaviour Furthermore, provide an extensive evaluation imposed migrations learning, as it can inflict overhead performance if operated uncoordinatedly.
