As an alternative solution to solve the tussles between the network operators and the peer-to-peer (P2P) applications, an informed peer selection (IPS) scheme like P4P is proposed. In IPS, each network operator installs a server that provides their network information to the peers as a guidance for peer selection and each peer chooses its communicating partner based on the guidance. Most existing...
In this letter, we introduce a novel packet scheduling algorithm, so called 2-tier Hierarchical Frame-based Queueing (2tHFQ) that provides a deterministic delay bound without sorting operation complexity. The key idea of 2tHFQ is to divide a given frame into multiple sub-frames with frame indices assigned, and then transmit input packets according to the frame index hierarchy. We analytically predict...
This paper presents the controller synthesis for a fine actuation system of a 3-DOF micro parallel positioning platform. The platform is composed of a dual stage servo system for realizing both long stroke and high precision, simultaneously. Among the dual stage, the fine actuation system is more important as it guarantees high speed and accuracy. First, a physics-based model for the fine actuation...
