Abstract This paper introduces the Priority‐Aware Federated Resource Allocation (PAFRA) algorithm, a novel resource allocation strategy designed for power line communication (PLC) systems. Leveraging federated learning framework, PAFRA optimizes distribution of limited spectrum resources across multiple nodes within residential environment. The algorithm integrates priority‐based time slot to effectively manage subchannel conflicts and employs Double Deep Q‐Network local training at each...

In this paper, we introduce token communications (TokCom), a unified framework to leverage cross-modal context information in generative semantic (GenSC). TokCom is new paradigm, motivated by the recent success of foundation models and multimodal large language (GFM/MLLMs), where communication units are tokens, enabling efficient transformer-based processing at transmitter receiver. potential opportunities challenges leveraging GenSC, explore how integrate GFM/MLLMs-based into systems...

Traditional performance analysis models based on the network calculus approach are not fit for time-triggered Ethernet (TTEthernet) due to porosity characteristic of timed-triggered (TT) traffic in TT-schedule. This paper introduces concept into arrival curve model TT and gives a general method worst-case end-to-end latency rate-constrained (RC) traffic. Experiments show that our give tighter bounds than results from other already known may be used guide design

Time-Sensitive Networking (TSN) evolves from Ethernet AVB in which the Credit-Based Shaping (CBS) is employed to guarantee deterministic transmission of traffic. In CBS, real-time performance traffic associated with credits can practicably settle uncertainty queueing and forwarding for stream-reservation Hence, optimization bandwidth allocation under CBS becomes a key point ensure guaranteed network. this paper, method proposed while requirements are satisfied. We first illustrate...

Smart Grid State Estimation (SE) aims at providing robust and accurate system state estimate for subsequent control operations to accommodate the disturbance of highly intermittent components. Conventional SE AC Power formulates estimation process as a non-convex optimization problem, which may reach local optimal stop. To compensate drawback, Semidefinite Programming (SDP) was recently applied convexify problem with rank one relaxation technique, shows perspectives approximately globally...

A broadcast encryption scheme with personalized messages (BEPM) is a in which broadcaster transmits not only encrypted to subset of recipients but also each user individually. Several (BE) schemes allow encrypts message for S public keys and any can decrypt the his/her private key. However, these BE provide an efficient way transmit In this paper, we propose transmission messages. Besides, based on multilinear maps ensure constant ciphertext size key achieve statically security. More...

To extend industrial Ethernet to guarantee real-time quality-of-service (QoS), the IEEE 802.1 Time-Sensitive Networking (TSN) task group has been developing a series of specifications, including flow control series, which Credit-Based Shaping (CBS) and Asynchronous Traffic (ATS) were defined in Qav standard Qcr draft respectively. While CBS is per-class scheduling strategy, ATS per-flow scheduling. analyze performance these strategies, comparison among CBS, Strict Priority Queuing (SPQ)...
