Abstract :
This paper presents a Hybrid Service Overlay Network (H-SON) for composing Service Specific Overlay Networks (SSON) in mobile environments. The overlay topology is organized into dynamically-adaptable hierarchical Chord rings reflecting node mobility and service quality transformation. Moreover, our loss-based utility function is used to predict the client´s QoE. Node resources can thus be automatically and dynamically redistributed and established SSONs can be reconfigured before quality levels deteriorate below acceptable levels. The proposed H-SON can accelerate the composition process by limiting service searches into bounded areas and can limit query broadcasts.
