Many networks in the real world are dynamically changing over time, and the community structure also changes accordingly. The community detection in the dynamic and constantly evolving network has received great attention from researchers. In order to uncover the community structure in the dynamic network, this paper proposes an incremental dynamic community detection algorithm based on node participation (NPICd). It defines the node participation to the community and the community fitness. In response to the changes of nodes and edges in the network, different update strategies are proposed to discover the community at different moments in an incremental manner. The experimental results on the real network show that compared with several widely used methods, our algorithm can quickly and accurately mine the community structure in the dynamic network. © 2021 IEEE.

To satisfy the service-side requirements for network layer authentication and traceability of users, this paper proposes a method for mobile terminal authentication and identity tracing based on IPv6 and blockchain. Our method introduces a new verification function (VEF) to verify the interface identification between the terminal and the 5G core network (5GC), thereby effectively enhancing the security of terminal access. Furthermore, considering the privacy protection of user identity information to prevent attackers from deducing encrypted content, it is necessary to periodically update encryption keys. Focusing on the practical deployment of VEFs on a network-wide scale and server-proximal for authentication and traceability, a time-varying key sharing scheme based on blockchain is proposed. The experimental section analyzes the communication performance and security of the proposed scheme, showing that our scheme does not significantly degrade the original network performance while providing substantial security gains.

BCdAN: A balanced method for community detection in attributed networks

Community detection in attribute networks is a fundamental problem in complex network analysis, aiming to identify well-connected communities based on both topology and node attributes. Although numerous methods for community detection in attribute networks have been proposed, they often fail to balance the use of structural and attribute information. In these approaches, attribute information typically plays a dominant role, while higher-order structural information, such as motif structures, is often neglected. To address this issue, we propose a balanced method for community detection in attribute networks (BCdAN). First, for structural information, we construct structural vectors for each node and employ a structure autoencoder to learn the nodes’ structural embeddings. Concurrently, for attribute information, we use an attribute autoencoder and a graph convolution module to jointly learn the nodes’ attribute embeddings, linking the two types of neural networks via a delivery operator. Furthermore, we introduce a self-supervised module that integrates both structural and attribute information from the target distribution to guide iterative updates of the model, thereby facilitating the community detection task. This approach enables a balanced utilization of both attribute and structural information, improving the identification of community features in attribute networks. Extensive experimental results demonstrate that BCdAN outperforms most baseline algorithms. © 2025 Elsevier B.V.

research on a Synchronization Algorithm of Look-Up Table in Open reconfigurable router

Chinese Journal of Electronics 2023年第3期19卷 419-422页

reconfigurable router with fast look-up table synchronization mechanism is necessary for Next generation network (NGN), which facilitates open and fast deployment of new services. Based on an open architecture, standard and highly credible interfaces among modules, a synchronization mechanism of the routing table and FIB (Forwarding information base) is put forward in this paper which is applicable to other look-up tables. This synchronization mechanism overcomes the inconsistency of look-up tables brought by the dynamic loading or unloading of forwarding planes. Anomalies can be rapidly discovered and eliminated by adding the appropriate synchronization messages to multi-queue, calculating the 16-bit Checksum in look-up table and resending parts of look-up table entries to the forwarding planes. A reconfigurable router prototype is built to simulate the scene. The results show that the proposed algorithm can realize high consistency and quick recovery in look-up tables, which improve stability and reliability of the reconfigurable router.

Superconducting electrodynamic suspension (EdS) presents numerous advantages, including large suspension gaps, high lift-to-drag ratios, and lower requirements for track irregularities. recent advancements in superconducting materials have further enhanced the feasibility of this technology, and hence multiple research institutions are actively developing and improving this high-speed rail technology. Superconducting EdS achieves passive suspension and guidance by the interaction between ground null-flux coils and onboard superconducting magnets, forming an electromechanical coupled system. Thus, electromechanical coupling modeling and equivalent experimental methods are essential in evaluating and optimizing this system. This article reviews the research on dynamic characteristics analysis of superconducting EdS, focusing on modeling and experimental methods. Firstly, it revisits the development history of superconducting EdS and the new opportunities brought by advancements in superconducting materials.
