Recently frozen 3GPP standard Release-16 has introduced vehicle platooning as a novel application in 5G Cellular Vehicle-to-everything (C-V2X), which is a technique to organize a group of close-following vehicles in column, aiming to improve traffic throughput and reduce fuel consumption. However, existing platoon protocols only focused on efficiency and ignored security. In this paper, we present a secure vehicle platooning protocol for 5G C-V2X with fast mutual authentication and efficient group key management. the protocol provides all maneuvers including merging, split, and member leaving with superior independence and flexibility. Relying on the enhanced 5G Authentication and Key Agreement (AKA) procedure, pseudo identity and signcryption keys are generated for each vehicle on startup by 5G Core Network (5GC) for conditional anonymity and mutual authentication. then, a protocol suit covering all platooning maneuvers is proposed based on group key distribution and updating. To prove the security of the proposed protocol, the Tamarin tool was employed to give a formal security verification under Dolev-Yao (DY) model. In addition, performance is analyzed in terms of computation cost and communication overhead, demonstrating its efficiency in authentication and group management.

Mobile devices face the problem of handover signal sources in mobile communication networks. It is particularly difficult to address this problem in 5G networks, because the coverage area of 5G base stations is smaller than that of traditional mobile communication networks, e.g., 4G networks. therefore, when a device is moving, it needs to frequently handover base stations to maintain the connection with the network in the 5G network. Given that 5G networks have high requirements for low latency and high reliability, new methods need to be proposed to optimize the selection of gNBs for devices. the prediction of the UEs' trajectory can reduce redundant handovers between devices and base stations. However, the prediction of the UEs' movement trajectory requires sufficient user movement data to achieve the desired prediction accuracy. For users with less trajectory data, inaccurate predictions may cause negative effects and even increase the number of handovers. In this paper, we propose a gNB handover model based on user similarity. the evaluation results show that our method can reduce the number of handovers by 50% compared with existing related solutions, which means that the proposed method will effectively reduce the transmission delay and enhance the robustness of the gNB.

this paper proposes an improved current type LC parallel resonant bi-directional isolated DC-DC converter with high efficiency and wide current regulation range for the application of interconnection of battery bank and DC bus in distributed energy storage as the interface between battery and DC bus. By establishing a simplified model of the converter and deriving the resonant inductor current, resonant capacitor voltage and output inductor current in the time domain, the resonant capacitor voltage gain curve and current transfer ratio curve are obtained in the average value, and the time domain analysis avoids the errors caused by the conventional fundamental analysis method when the switching frequency differs from the resonant frequency. the above derived current transfer ratio curves show that the proposed converter has a wide current regulation range for energy storage applications, and therefore, the converter can realize the control of energy storage charging and discharging with frequency modulation. Finally, a 7.5kW, 50V to 300V prototype with a power density of 1.15W/cm3 and a peak efficiency of 96.70% is built, and the validity of the previous analysis is experimentally verified. © 2022 ieee.

We explore the heterogeneous acceleration of graph processing on a platform that tightly integrates an FPGA with a multicore CPU to share system memory in a cache-coherent manner. We design an accelerator for the scatter phase of scatter-gather vertex-centric iterative graph processing. the accelerator accesses graph data exclusively from system memory, sharing it at the cache line granularity with the CPU, thus enabling the concurrent use of both the accelerator and software threads. We implement and evaluate the accelerator on the second generation Intel Heterogeneous Architecture Research Platform (HARPv2). Our evaluation, using two key graph processing kernels and both synthetically-generated and real-world graphs, shows that: (1) our accelerator delivers a performance improvement of about 2.4X over a single CPU thread, (2) our concurrent use of software and hardware is efficient and delivers speedups over the use of just software threads or just the accelerator, and (3) heterogeneous hardware-software acceleration delivers high graph processing throughputs. these results demonstrate the viability and promise of combined CPU-FPGA processing in contrast to the traditional offload model that leaves the CPU idle during acceleration.

HPC and distributed systems are the driving force for the advancement of many emerging technologies, such as exascale systems, quantum machines, terabit networking, 5G/6G wireless, and cloud/edge computing. the tasks of systems and network telemetry are a key element for effective operations and management of the advancement of many emerging systems and technologies, and require more scalable telemetry and analysis techniques for comprehensive monitoring and analysis. Various input sources such as end systems, switches, firewalls, intrusion sensors and the emerging network elements speaking with different syntax and semantics make organizing and incorporating the generated data challenging for the quantitative and qualitative analysis. this workshop looks for new approaches and methods at the intersection of HPC systems and data sciences to address these difficult challenges of emerging technologies from the diverse angles of systems/network performance, availability, reliability, and security.

this paper proposes a real-time power system simulation framework that is capable of simulating steady state and electromechanical transients of power systems, with submillisecond time resolution. the framework can integrate power system component models packed as reusable Functional Mockup Units (FMUs) to flexibly create power system simulations without the need to recreate new models for different power systems. the integration of individual components is based on a novel model decomposition method, which enables the FMU reuse in different system contexts, as well as a parallel simulation execution onto multi-core machines. Furthermore, the paper proposes methods to optimize the allocation of components to cores and shows that the framework can simulate a medium voltage distributed electrical grid of about 20 components in real-time on a commodity multi-core machine.
