The demand for continual machine learning in the context of limited computational resources and data availability is critical in the evolving landscape of the connected digital world. Current network applications predominantly rely on deep learning models that require labor/computation-intensive training processes. These models often struggle to effectively adapt to new data while preserving performance on previously acquired knowledge. In this paper, we introduce a lightweight framework for continual knowledge adaptation and learning designed to address these challenges. To prevent disruption of existing services, we propose an attention-based adapter that integrates seamlessly with the existing vision model to encode new incoming data. The weights of the original model are kept fixed during the adaptation process, ensuring the preservation of previously learned knowledge. Furthermore, to enhance learning efficiency and accelerate convergence with new data, we implement a knowledge fusion mechanism that facilitates interaction between existing knowledge and information from new data. Our framework is modular, enabling flexible deployment across distributed devices. The adapter and knowledge fusion module are implemented at each stage with minimal trainable parameters, optimizing resource usage. Extensive experiments and ablation studies validate the effectiveness of the proposed framework. © 2024 IEEE.

A parameterized benchmark suite of hard pipelined-machine-verification problems

We present a parameterized suite of benchmark problems arising from our work on pipelined machine verification, in the hopes that they can be used to speed up decision procedures. While the existence of a large number of CNF benchmarks has spurred the development of efficient SAT solvers, the benchmarks available for more expressive logics are quite limited. Our work on pipelined machine verification has yielded many problems that not only have complex models, but also have complex correctness statements, involving invariants and symbolic simulations of the models for dozens of steps. Many of these proofs take hundreds of thousands of seconds to check using the UCLID decision procedure and SAT solvers such as Zchaff and Siege. More complex problems can be generated by using PiMaG, a Web application that we developed. PiMaG generates problems in UCLID, SVC, and CNF formats based on user-provided parameters specifying features of the pipelined machines and their correctness statements. © IFIP International Federation for Information Processing 2005.

Unmanned-aerial-vehicle based optical camera communication system using light-diffusing fiber and rolling-shutter image-sensor

We put forward and demonstrate a light-diffusing fiber equipped unmanned-aerial-vehicle (UAV) to provide a large field-of-view (FOV) optical camera communication (OCC) system. The light-diffusing fiber can act as a bendable, lightweight, extended and large FOV light source for the UAV-assisted optical wireless communication (OWC). During UAV flying, the light-diffusing fiber light source could be tilted or bended;hence, offering large FOV as well as supporting large receiver (Rx) tilting angle are particularly important for the UAV-assisted OWC systems. To improve the transmission capacity of the OCC system, one method based on the camera shutter mechanism, which is known as rolling-shuttering is utilized. The rolling-shuttering method makes use of the feature of complementary-metal-oxide-semiconductor (CMOS) image sensor to extract signal pixel-row by pixel-row. The data rate can be significantly increased since the capture start time for each pixel-row is different. As the light-diffusing fiber is thin and occupies only a few pixels in the CMOS image frame, Long-short-term-memory neural-network (LSTM-NN) is used to enhance the rolling-shutter decoding. Experimental results show that the light-diffusing fiber can satisfactorily act as an "omnidirectional optical antenna" providing wide FOVs and 3.6 kbit/s can be achieved, accomplishing the pre-forward error correction bit-error-rate (pre-FEC BER = 3.8 × 10−3). © 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

In an indoor wireless network environment com-posed of Internet of Things (loT) devices, there can be devices that transmit data in a weak link due to obstacles and low transmission power. To solve the problem without additional energy consumption of devices, a new Medium Access Control (MAC) protocol is required for receiving data from the devices in the weak link. In this paper, we propose an energy-efficient MAC protocol that the AP can collect data by using a Hybrid-Reconfigurable Intelligent Surface (H-RIS). In the proposed network, the Access Point (AP) can distinguish the packet-level failure of the weak link and control the H-RIS to receive data from the device. Using simulations, we have shown that our proposed method can enhance the performance of the network throughput and energy efficiency of devices. © 2023 IEEE.

As researchers push for Exascale computing, one of the emerging challenges is system resilience. Unlike fault-tolerance which corrects errors, recent reports suggest that resilient systems will need to continue to make progress on an application despite faults. A first step in developing a resilient system is to have robust, scalable system monitoring. The work described here presents a novel, minimally-invasive system monitor that operates over a separate network. We analytically characterize the performance for an arbitrary set of nodes and demonstrate a working implementation of the design. We argue that the hardware approach is inherently superior to the ad hoc, software techniques currently employed in practice. © 2010 IEEE.

A key problem in Rechargeable Wireless Sensor Networks (WSNs) is determining the maximum amount of data that can be collected by a sink over a given time period. This maximum is constrained by link capacity and critically, by the available energy at each node. In this paper, we consider a novel approach to increase the maximum flow rate by exploiting recent advances in Wireless Power Transfer (WPT). Specifically, we deploy a finite number of WPT capable rovers next to bottleneck sensor nodes with the aim to increase the max flow rate of a WSN. We formulate a Mixed Integer Linear Programming (MILP) to determine the routing and the set of sensor nodes that are to be 'upgraded' in order to achieve the maximum flow rate. We also outline a novel heuristic, called Path, to place rovers in large scale WSNs. Our results show it is able to attain on average 85.9% of the optimal flow rate. © 2015 IEEE.

Performance analysis of WDM optical networks with wavelength usage constraint

Due to power considerations, it is possible that not all wavelengths available in a fiber can be used at a. given time. In this paper, an analytical model is proposed to evaluate the blocking performance of wavelength-routed optical networks with and without wavelength conversion where the usable wavelengths in a fiber is limited to a certain maximum number, referred to *** usage constraint. The effect of the wavelength usage constraint is studied on ring and mesh-torus networks. It is shown that the analytical model closely approximates the simulation results. It is observed that increasing the total number of wavelengths in a fiber is an attractive alternative to wavelength conversion when the number of usable wavelengths in a fiber is maintained the same. © 2003 by Springer Science+Business Media Dordrecht.

In this paper, we propose a new architecture for tunable Fabry-Perot (FP) interferometer using fiber Bragg gratings (FBGs). The main feature of the architecture is its ability to increase the finesse using a potentially low cost technique. Furthermore, it decreases the power loss of the filtered channel and can be implemented easily in practice. © 2009 IEEE.
