Abstract: Based on the Skyline computation algorithm of static data in Chord network and Skyline computation algorithm in distributed environment, this paper proposes a Skyline computation algorithm of dynamic data in Chord network. It realizes real-time update of data through the model of window, and users can get their real-time and interesting information more accurately. Theoretical analysis and experimental results prove that this algorithm realizes load balance of network, has good progressive and can effectively reduce consume of network bandwidth.
