Anchor–Chain: A Seamless Producer Mobility Support Scheme in NDN
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017Co-Authors: Yizhe Zheng, Xuewei PiaoAbstract:Named Data Networking (NDN) has natural advantages in the consumer mobility support for its design characteristics, while the producer mobility support was left unspecified. Some producer mobility support schemes have been proposed in recent years, which better solved the huge overhead caused by the route aggregation in normal NDN, yet critical issues like long handover latency and high packet loss rate still remain. In this paper, we improved and optimized a quite popular method Anchor-based solution by setting multi-level Anchor nodes strategically based on the network topology hierarchy, which we called Anchor–Chain, and the Interest packet forwarded to the producer would pass through it. After the producer moved, the newly generated Anchor–Chain would reuse the previous forwarding path as far as possible to guide more Interests to the new location of producer and reduce the Interest packets drop rate. Besides, we introduce a mobility preprocess mechanism that takes the advantage of connectionless and multi-path forwarding in NDN to establish the future Interest forwarding path in advance, which assists the producer performs “seamless” handover. By numerical analysis, our approach can reduce the handover latency and improve the response ratio compared with the main current solutions.

Robust Tension Control of the Anchor Chain of the Ship Windlass under Sea Wind
Journal of Computers, 2010Co-Authors: Wei GuAbstract:Constant tension control of Anchor Chains is important for safety of moored ships. The core driving component of an Anchor windlass system is an induction motor which is a multi-variables, coupled nonlinear system, and is difficult to control. To surmount this problem, a control scheme based on the inverse system method is introduced to linearize an induction motor into a decoupled linear system, and linear controllers are then designed to complete the control task. In addition, theoretical analysis based on the Lyapnov method is carried out to investigate the influence of the time-varying rotor resistance to the control scheme suggested. Both theoretical analysis and numerical simulations show this control scheme is able to keep Anchor Chains at desired tension under sea wind at a time-varying rotor resistance.
