Stream-based systems are frequently subject to changes in their operational environments due to fluctuations in the available computation and communication resources. Dynamic adaptation is a mechanism to improve the fitness of such systems. However, adaptation can block one or more streams thus inadvertently affecting the timeliness properties of streams. This paper describes AdaptStream, an adaptation framework that provides timeliness support for stream-based adaptations. We introduce the concept of fluidity to measure the temporal alignment of stream synchronization during adaptation. We present a scheduling algorithm that calculates the time-bounded schedule of adaptation actions on multiple streams to achieve the fluidity requirement that is traded off against available resources and the smoothness requirement of individual streams.
