Software-defined networking (SDN) is a pioneering network paradigm that strategically decouples the control plane from data and management planes, thereby streamlining administration. SDN's centralized makes configuring access list (ACL) policies easier, which important as these frequently change due to application needs topology modifications. Consequently, this action may trigger modifications at SDN controller. In response, controller performs computational tasks generate updated flow rules in accordance with modified ACL installs plane. Existing research has investigated reactive installation changes result packet violations inefficiencies. Network becomes difficult deleting inconsistent computing new per policies. The proposed solution efficiently handles policy phenomena by automatically detecting accordingly along caching adding A comprehensive analysis of both proactive mechanisms carried out achieve this. To facilitate evaluation mechanisms, are modeled using 5-tuple structure comprising Source, Destination, Protocol, Ports, Action. resulting then translated into implementation file transmitted Subsequently, utilizes calculate necessary caches hash table addition installing them switches. simulated Mininet Emulator set policies, hosts, results presented varying different time instances, inter-packet delay timeout value. simulation show rule better than mechanism respect throughput, violations, successful delivery, normalized overhead, detection end-to-end delay. solution, designed be directly used on controllers support Pyretic language, provides flexible efficient approach for installation. can employed administrators implementing It also integrated monitoring debugging tools analyze effectiveness mechanism.

In the dynamic landscape of saliency detection, convolutional neural networks have emerged as catalysts for innovation, but remain largely tailored RGB imagery, falling short in context infrared images, particularly memory-restricted environments. These existing approaches tend to overlook wealth contour information vital a nuanced analysis images. Addressing this notable gap, we introduce novel Two-branch Edge Guided Lightweight Network (TBENet), designed explicitly robust image detection. The main contributions paper are follows. First, formulate detection task two subtasks, enhancement and foreground segmentation. Therefore, TBENet is divided into specialized branches: prediction branch extracting target map generation separating from background. first employs an encoder–decoder architecture meticulously delineate object contours, serving guiding blueprint second branch. This latter segment adeptly integrates spatial semantic data, creating precise that refined further by innovative edge-weighted loss function. Second, enhance feature integration capabilities, propose depthwise multi-scale multi-cue modules, facilitating sophisticated aggregation. Third, high-level linear bottleneck module devised ensure extraction rich information, replacing standard convolution with convolution, it beneficial reduce model complexity. Additional, number channels maps each stage decoder lightweight model. Last, construct ship dataset Small-IRShip train evaluate our proposed Experimental results on homemade publicly available datasets, namely RGB-T IRSTD-1k, demonstrate TBENet's superior performance over state-of-the-art methods, affirming its effectiveness harnessing edge incorporating advanced strategies.

Many Industrial Internet of Things (IIoT) applications require wireless networks with low power consumption, latency, and secure communication. The IPv6 over the TSCH mode IEEE 802.15.4e (IETF 6TiSCH) standard has been created to fulfill these requirements provide reliable efficient communication, specifically in industrial environments. A authentication process is first step towards ensuring privacy security a IoT network. IETF Constrained Join Protocol (CoJP) centralized protocol developed by 6TiSCH Working Group which used manage node bootstrapping processes through entity named as Registrar/Coordinator (JRC). This requires joining nodes be authenticated via JRC entity. Centralized within exhibits scalability limitations beyond small-to-medium deployments, necessitating alternative approaches for requiring large number deployed nodes. Using distributed approach where role among network can help mitigate this drawback. In paper, placement method decentralized introduced address challenges heuristic solution that optimise Proxy-JRC proposed. Experimental results 2,3 4 placed proposed show up 25% improvement terms key update time 22% consumption. These highlight benefits employing mechanism meet communication large-scale networks.

Abstract Online voting is gaining traction in contemporary society to reduce costs and boost voter turnout, allowing individuals cast their ballots from anywhere with an internet connection. This innovation cautiously met due the inherent security risks, where a single vulnerability can lead widespread vote manipulation. Blockchain technology has emerged as promising solution address these concerns create trustworthy electoral process. offers decentralized network of nodes that enhances transparency, security, verifiability. Its distributed ledger non‐repudiation features make it compelling alternative traditional electronic systems, ensuring integrity elections. To further bolster online voting, we propose DemocracyGuard platform on Ethereum blockchain, which incorporates facial recognition authenticate voters. By leveraging advancements, aims provide secure resilient for paving way its broader adoption revolutionizing landscape.
