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