Research ArticleOpen accessPhrase in the titleSelf-Managed Federation of MQTT Brokers with Dynamic Topology ControlBruno Bevilaqua, Marco Aurélio SpohnThe Message Queuing Telemetry Transport (MQTT) protocol is most used in Internet of Things (IoT) applications. The protocol implements the Publish/Subscribe (P/S) communication model. Publishers are entities providing data to a server (broker), and subscribers are those showing interest in such data. The standard MQTT scenario relies on a single broker, a potential bottleneck, and a single point of failure. … …Journal of Computer Science, Vol. 19, Issue 11 · 18 Oct 2023 · 5,248 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProposing a Hybrid Topological Organization for Non-Misbehaving Nodes with Optimal Path Selection Using Game-Theoretic ApproachKanmani S, M. MuraliIn dynamic communication networks, improvement of energy efficiency is one of the major challenges for reliable communication. By considering this challenge, we focus to develop the topology of the network. In this study, we design a hybrid star-mesh topology for minimizing the latency as well as energy consumption of the network. In the hybrid network topology, the Ad-Hoc On-Demand Multipath … …Journal of Computer Science, Vol. 19, Issue 10 · 31 Aug 2023 · 5,397 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAuthentication Based and Optimized Routing Technique in Mobile Ad hoc NetworksS. Varadhaganapathy, A. M. Natarajan, S. N. SivanandamProblem statement: An Ad hoc network has been defined as a self-organizing, dynamic topology network formed by a group of wireless mobile nodes. Minimal configuration, absence of infrastructure and quick deployment, would make ad hoc networks convenient for emergency situations other than military applications. In recent years, security in Ad hoc Networks as a research topic had started to receive … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved Location aided Cluster Based Routing Protocol with Intrusion Detection System in Mobile Ad Hoc NetworksS. Mangai, A. TamilarasiProblem statement: Routing and security are the main challenges for ad hoc networks due to dynamic topology as well as resource constraints. A designed protocol must provide scalable routing with better security. Lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. And also resource constraints such as limited energy and size … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTopology Discovering and Power saving Mechanism for Routing in a Tree of Ad-hoc Wireless NetworksArwa ZabianPower management in mobile network is an open challenges where the power level in the network influences the network life time. However, there are a trade off between the power consumption and the connectivity in mobile networks. We present a topology control mechanism and a routing protocol for Ad-Hoc wireless networks that chooses the shortest path given the lower power … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Knowledge Driven Multi-Scale Spatiotemporal Fusion Framework for Reliable Multi-Horizon Traffic Flow ForecastingDeepika M S, P. Deepa Shenoy, Venugopal K RAccurate traffic flow forecasting remains a core challenge in intelligent transportation systems. Urban traffic patterns are characterised by complex spatiotemporal dependencies and inherent uncertainties, which complicate traffic forecasting. This study proposes a Dynamic Knowledge-Driven Spatiotemporal Fusion (DKDMSF) architecture to extract features of Multi-Scale traffic dynamics across various temporal traffic horizons. DKDMSF integrates Dynamic Spatial Attention (DSA) and Adaptive Graph Learning … …Journal of Computer Science, Vol. 22, Issue 9 · 30 Sep 2026 · 413 accessesView PDFCite
Research ArticleOpen accessIn the abstractTAGN-IDC: Implicit Discrete Constraints for Tsunami Aware Graph Neural Networks in Spatial Evacuation RoutingSularno, Wendi Boy, Putri Anggraini et al.Tsunami evacuation route requires rapid identification of safe evacuation paths under dynamically changing hazard conditions. A major challenge is incorporating hard binary road-blockage constraints caused by tsunami inundation while maintaining end-to-end differentiability for deep learning models. Existing approaches commonly rely on continuous relaxations or stochastic sampling techniques, which either compromise physical feasibility or increase computational complexity. This study proposes the … …Journal of Computer Science, Vol. 22, Issue 9 · 24 Sep 2026 · 704 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of an AI-Based Controller for a Positive Output Superlift DC-DC ConverterRicha Adlakha, Ashish Grover, Neha Chaudhary et al.DC-DC converters have emerged as crucial components in various industrial applications and form an integral part of power supplies based on switch-mode. Solar energy has garnered increasing significance owing to the scarcity of non-renewable fuels and its abundant availability. Photovoltaic (PV) technology, characterized by the arrangement of numerous series and parallel-connected PV cells within modules, generates DC output. Consequently, the … …Journal of Computer Science, Vol. 22, Issue 2 · 17 Feb 2026 · 1,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Optimization to Trust Enhanced Secure Routing Optimization with IABC and CGWAA for MANETYuvaraja Panneer Selvam, Suganthi PerumalRouting in Mobile Ad Hoc Networks (MANET) presents significant challenges due to the dynamic nature of network topology. Optimal route selection and efficient route discovery are matched by effective routing in MANET.

Research ArticleOpen accessIn the abstractEffect of Load and Routing Protocols on Networks on Chip (NoC): An AnalysisShaily Jain, Chander Prabha, Ayman Noor et al.Communication infrastructure for multi-core Systems-on-Chip (SoCs) is provided by Network-on-Chip (NoC). Point-to-Point (P2P) and bus-based communication systems are NoCs and are two communication channels of NoC that can probably overcome the scalability and performance restrictions of NoC. Latency and throughput are two of the essential characteristic metrics measured for a routing algorithm that affect the performance of a given NoC. … …Journal of Computer Science, Vol. 20, Issue 11 · 29 Aug 2024 · 5,273 accessesView PDFCite
