Coordinated with cloud computing, this technology becomes even more powerful, cost-effective, and reliable. These advancements are rapidly being integrated into modern healthcare through innovations such as smart ambulances, remote monitoring systems, and smart hospitals, enhancing tracking, analysis, and alerting capabilities. However, these innovations also bring challenges, particularly in task allocation and resource management for safety-critical systems that must meet stringent quality of service while efficiently utilizing resources. This paper introduces a new heuristic Three-Tier Prioritization based Multiflow Scheduling (TTPMS) approach for smart healthcare in cloud, utilizing the adaptive multi-criteria decision-making. The proposed TTPMS algorithm prioritizes tasks across three levels, considering factors such as urgency, deadlines, budget, and impact value within the workflow, and then dynamically selects the most suitable virtual machine for allocation. Performance comparisons were made against traditional approaches like the Prioritized Sorted Task-Based Algorithm (PSTBA) and the Max–Min algorithm. Experiments conducted using the Eclipse IDE with Java, demonstrated that the proposed approach significantly outperforms traditional algorithms across multiple metrics, including success rates for deadlines and budgets, as well as the resource utilization. It achieved a 98% deadline adherence rate, outperforming Max–Min (93%) and PSTBA (60%). Additionally, TTPMS surpassed budget adherence metrics, achieving a 76% success rate compared to PSTBA (72%) and Max–Min (70%). For combined adherence to both deadlines and budgets, TTPMS achieved a 74% success rate, outperforming PSTBA (33%) and Max–Min (63%). These results highlight the effectiveness of TTPMS in scheduling the healthcare applications.</div></div>","PeriodicalId":54784,"journal":{"name":"Journal of Network and Computer Applications","volume":"238 ","pages":"Article 104143"},"PeriodicalIF":7.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While manual identification of vessels can be challenging, advancements in Cryptographic hash functions, Deep Learning technology, and image processing have simplified the task. However, existing techniques like YOLOv3, with its struggles in handling unusual aspect ratios, YOLOv5’s low mean average precision, and R-CNN’s increased complexity and lack of privacy preservation, motivate the need for an improved approach. In lieu of this, we propose an Extended-YOLOv7 model as a more effective detection solution due to its favorable characteristics like CSPNet, Feature Fusion Module (FFM), Spatial Pyramid Pooling (SPP), and Non-Maximum Suppression (NMS). Additionally, utilization of the gradient descent algorithm aims to optimize system performance. To ensure privacy preservation, our work employs the widely recognized and secure hashing algorithm SHA-256, which is extensively used for data security. The proposed system facilitates detecting vessel traffic in designated areas such as ports and harbours as well as enables real-time vessel detection and tracking for enhanced security and safety purposes. In addition to safeguarding sensitive data, our research addresses compliance with privacy regulations, mitigates the risks of data breaches, and upholds ethical considerations. With the integration of these driving factors, this work strives to elevate the security analysis of detected maritime vessels, foster a sense of trust and assurance, and promote the use of ethical data management techniques.

However, existing solutions focus only on user anonymity and are severely exposed to fake energy offers that can lead to denial-of-service attacks. Moreover, the off-chain communication mechanism used for private energy negotiation is computationally inefficient. This paper proposes a Multi-Level Privacy-Preserving system (MuLPP) for blockchain-based bilateral P2P-ET that provides user anonymity, energy price and energy amount privacy while protecting against fake energy offers. To address the privacy concerns in a comprehensive way, MuLPP offers three levels of privacy: public-level, energy authority-level and participant-level. MuLPP is based on blockchain smart contracts, RSA accumulators, public key aggregation and BLS-based multi-signature to achieve user anonymity, data privacy, robustness against fake energy offers and security in off-chain negotiation. This paper also proposes a permissioned anonymous decentralized P2P off-chain communication protocol, known as PADPeC, to enhance the privacy and performance of off-chain energy negotiations. Experimental results conducted in a real environment indicate that MuLPP provides 75 to 100 times lower on-chain latency. On the other hand, PADPeC reduces the message-sending time and the number of message exchanges in the off-chain communication by a factor of 4123 and 7.88 respectively compared to the existing systems. Formal security verification conducted using AVISPA security verification tool also revealed that the system is secure against various attacks such as sybil, network flooding and fake energy offer attack.</div></div>","PeriodicalId":54784,"journal":{"name":"Journal of Network and Computer Applications","volume":"237 ","pages":"Article 104141"},"PeriodicalIF":7.7,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current solutions fail to balance security and efficiency. To address insecure interactions arising from producer mobility, we introduce a protocol for blockchain-based mobile producer authentication (BAS-NDN). Our protocol relies on a novel elliptic curve-based certificateless signcryption scheme, which is easy to deploy, provides both signature and encryption, and avoids complex certificate management and key escrow problems. This makes it suitable for secure and efficient mobile management in NDN. In addition, the proposed scheme efficiently authenticates the producer’s prefixes by enforcing the producer to publish routing updates that use only valid prefixes. This design renders it resistant to prefix hijacking attacks. Through analyzing under the random oracle model, it is also resistant to both Type I and Type II adversaries present in certificateless signcryption.

Cloud computing presents a significant obstacle to efficient resource usage and balance of loads due to the dynamic nature of consumer requirements and tasks. The inflexibility of conventional methods guarantees inadequate outcomes and waste of resources. Motivated by improved cloud infrastructure management, the present research introduces a novel approach to load optimization and migrating Virtual Machines (VMs) based on agents modelled and Internet of Things (IoT) devices. This research aims to boost cloud performance primarily by optimizing the utilization of resources and distribution of workloads. Hence, a novel approach, the Optimized Virtual Machine Migration Scheme (OVMMS), is introduced that uses the Squirrel Search Algorithm (SSA) for migrating VMs. By emulating squirrel behaviour during migration and search, these agents maximize load balance and the distribution of resources. During the analysis, IoT devices were enabled to monitor and control cloud resources to minimize wastage. Results from experimental analysis demonstrate that the proposed strategy outperforms the state-of-the-art in numerous key areas, including service dissemination, load mitigation, managing failures, mitigating time, and endurance of VM. The results show that the number of failures and the time it takes to mitigate them have dropped dramatically, while services' efficiency and distribution rates have improved substantially. The results illustrate that the squirrel-driven approach holds significant potential for addressing vital issues in cloud computing scenarios. This method asserts that optimizing the distribution of resources and the allocation of workloads may improve systems adaptability, service dependability, and cloud infrastructure operations.
