    Modeling of wave-induced drift based on stepwise parameter calibration by Kui Zhu, Xueyao Chen, Lin Mu, Lin Mu, Lin Mu, Dingfeng Yu, Dingfeng Yu, Runze Yu, Zhaolong Sun, Tong Zhou, Tong Zhou

    Published 2025-01-01
    “…The motion of waves in water causes the slow movement of drifting sea targets—a phenomenon usually ignored in target-drift prediction models for maritime search and rescue (SAR). This study examined the wave-induced drift’s influence on field-observation experiments involving two common, differently sized SAR targets—an offshore fishing vessel (OFV) and a person in the water (PIW)—using parameter stepwise calibration and machine-learning (ML) methods. …”

    Pre-authentication and group management based secure handover for space-earth integration network by Jia-nan HONG, Shao-hua LI, Kai-ping XUE, Pei-lin HONG

    Published 2016-07-01
    “…In space-earth integration network,high-speed movement of space nodes brings in the problem of fre-quent satellite access router (SAR) handover.A group-based secure handover scheme for multiple mobility nodes (MN) utilizing satellite trajectory prediction was proposed.By using the movement features of the corresponding entities,an efficient aggregation mechanism for the interaction message occurred during the multi-MN handover was put forward.By using predictable satellite trajectory,authentication and session key agreement between new SAR and MN was accomplished beforehand with the secure context.Compared with existing schemes,the proposed scheme can provide necessary security features,lower the handover delay,and reduce the computation and commu-nication overhead of mutual authentication and key agreement.The proposed scheme well suits the space-earth inte-gration network,where the satellite node is energy constraint.…”
