Wireless Sensor Network (WSN) has covered broad areas as a promising networking technique. The sensor nodes are facing multiple menaces, especially Distributed Denial of Attack (DDoS). Yet, existing DDoS mitigations are inadequate to be applied in WSNs due to the constrained resources. In this paper, we propose an activatable DDoS defense which is adaptable for WSNs. We design an activation mechanism to achieve the state transition of nodes with adjustable overhead. Furthermore, a probabilistic bootstrap percolation in connected Random Geometric Graph (RGG) is utilized to model the dynamic activation process. We analyze the critical threshold of phase transition theoretically and provide the proof. Finally, we numerically analyze the process and verify the theoretical results by comprehensive simulations.

This article focuses on the performance analysis of cooperative systems hybridizing MIMO-RF/MIMO-FSO and error correcting codes including GC-LDPC codes in FSOs. In this double-hop relay system composed of links with several inputs and multiple outputs at radio frequency and with multiple inputs and multiple outputs in FSO. In this system the source transmits the information to the relay by RF links, the relay processes the information received from the source and retransmits it to the destination by FSO links. To decode the data we used two-phase local-global decoding and to eliminate interference between source-relay links and relay-destination links we use interference alignment (IA) technique. It is also assumed that the source-relay link undergoes Rayleigh fading, while the relay-destination links undergo Gamma-Gamma model fading. Using DF relay technology, hybrid MIMO-RF/MIMO-FSO systems combine the advantages of RF and FSO communication technologies. The use of hybrid MIMO- RF/MIMO-FSO cooperative transmission systems improves network reliability and transmission. In this work, we carried out a simulation study on the distribution of the total transmission power at the source and the relay level to understand the best allocations between the source and the relay in order to guarantee a good quality of reception of the data transmitted to the destination. This work also presents studies on the different combimaision techniques. The results of our simulations show that the MIMO-RF/MIMO-FSO system based on GC-LDPC codes gives better performance compared to MIMO-RF/FSO and RF/FSO systems based on the same codes but also with conventional systems without the use of codes.

Optical coherence tomography (OCT) has been widely adopted in various areas for its noninvasive and high-resolution properties. Due to it low-coherence interferometry nature, however, OCT inevitably suffers from speckle noise, which hides structural information in OCT images and thus degrades the clinical diagnosis accuracy. So far various algorithms have been proposed for OCT speckle denoising, yet few studies have evaluated the influences of speckle noise distributions on the denoising effects. This paper studies the influences of speckle noise distributions in OCT despeckling process, and a twostep filtering mechanism, namely, Augmented Lagrange function minimization and Rayleigh alpha-trimmed filtering (AR) scheme, is proposed for OCT speckle noise reductions. The speckle noise distribution models are established and estimated first, and then two different filtering mechanisms are designed for those noise distributions, respectively. Simulations with both synthetic and OCT images are conducted to verify the effectiveness of the AR scheme. Results show that AR method can suppress OCT speckle noises effectively, and outperforms the best existing methods in different cases, yet with less time computations.

In networked systems, traffic is one of the most fundamental dynamical processes. Since the betweenness of nodes in complex networks can theoretically represent the traffic load of nodes, a routing strategy for two-layer complex networks is proposed based on the betweenness centrality. With the routing strategy, the packets are set to bypass the nodes with large betweenness in the logical layer network and the physical layer network. The traffic loads can be redistributed from the central nodes to the noncentral nodes efficiently. The routing strategy can alleviate the congestion and promote the traffic capacity of multilayers complex networks. Compared to the shortest path routing (SPR) and improved active routing (IAR) strategy, simulation results show that the two-layer complex networks capacity is considerably enhanced when $beta$=0.75..

A novel double and triple band monopole antenna covering WiFi, WiMax and 5G application is presented in this article. The proposed antenna is evolved from the traditional quarter-wave monopole antenna. Two L-shaped strips were integrated on both sides of the quarter wave monopole antenna to enable double-band and triple-band frequency operation. The antenna exhibits moderate gain over the desired frequencies of operation. The proof-of-concept is validated with simulated results. The integration of L-strips opens a possibility to convert a single band monopole antenna into a double band or triple band antenna without much design complexity. Moreover, the independent tuning nature of the frequency bands in the proposed design enables us to conFigure the antenna at any desired frequency bands.

Detecting infrared small target that lack texture features and shape information in cluttered environments is a challenging task. In this paper, we propose a novel feature fusion approach of feature pyramid networks (FPN) for effective detection of infrared small target. To extract the feature maps of infrared small target in different layers of the network and to fuse them effectively, we propose a multi-scale feature fusion module. Experimental results show that our proposed method performs much better than traditional approaches for infrared small target detection. In particular, our proposed method still achieves satisfactory results compared to other deep learning-based methods. In addition, we conducted ablation study of the network structure and the experimental results demonstrate the effectiveness of our proposed novel FPN.

We provide a survey of different categories of communication systems to which conventional decision-making schemes which are aware of the goals and constraints of each system are enhanced Federated Learning algorithms. Formulating new Federated Learning-oriented strategies key design aspects and open research issues (e.g. resource optimization, reliability) are presented from an empirical research view. Controlled experiments at the level of simulation or real-life data sets indicate that FL-based communication schemes become context- and mobility- aware with the mission of optimizing the decisions of each design. Also, empirical research results present a goodness of fit of FL schemes into hybrid, multilayer communication systems as they are emerging in mobile-cloud networks, 5G, and IOT.

Underwater wireless sensor networks (UWSNs) face new threats and prospects as a result of recent technological advances. Providing large-scale, and high spatial-temporal resolution of ocean exploration data is highly crucial in environmental monitoring, ocean energy production, and marine science research. Underwater wireless communications, however, face many challenges, including bandwidth constraints, multipath propagation, and fading, long end-to-end propagation latency, and limited power supply with batteries. Underwater monitoring tasks are seriously hampered by data losses due to low link qualities and collisions. Therefore, in UWSN, the design and implementation of an energy-aware, secure, and less propagation delay concern MAC protocol is important. This paper presents a simulation-based performance analysis for a multi-directional data access control system using UAN-CW, UAN-RC, and UANALOHA MAC protocols in an underwater wireless network. A two-way half-duplex acoustic modem has been implemented to analyze the consumed and remaining energy of the network. To assess MAC protocols evaluation, we compared three MAC protocols focusing on throughput, delay, packet delivery ratio, and energy consumption. Simulations were carried out by using the ns3 simulation tool. The simulation results show that UAN-CW MAC protocol outperforms two protocols in respect of throughput, delay, packet delivery ratio, and energy consumption. However, the remaining energy for UAN-RC-MAC is higher than others.

There are some problems in the surface defect detection of industrial aluminum products, such as small defect samples, extreme length-to-width ratio of defect, low precision of small defect detection, etc. To solve these problems, an aluminum surface defect detection algorithm is proposed based on improved Faster RCNN. The number of defect samples is increased by data augmentation, and the residual network ResNet50 is employed as the backbone feature extraction network to extract aluminum defect features. Then the path enhancement feature pyramid network (PAFPN) is added to the backbone feature extraction network to form a multi-scale feature map which strengthens the utilization of feature information from the lower layers. Soft non-maximum suppression (Soft-NMS) is used to further improve the detection performance of the algorithm. Results show that the mean average accuracy (mAP) of the proposed algorithm is 78.8%, which is 2.2% higher than the original algorithm.
