Major service providers started to deploy geographically-distributed edge servers several years ago. A major challenge in geographically distributed edges is task scheduling, i.e., how to assign various tasks submitted by mobile users to distributed edges so as to optimize some metric. However, it is not easy to perform task scheduling in geographically-distributed edges. We observed that there are three major challenges in designing an efficient task scheduling solution in dynamic edge environments: heterogeneous tasks, dynamic edge networks, and heterogeneous edge servers. In this paper, we pursue a black-box solution for task scheduling in the collaborative edge environment while not relying on detailed analytical performance modeling. We propose Reload, an intelligent deep reinforcement learning-based task scheduler. Reload learns a policy purely based on the known information, without foreseeing the future. Reload depicts its policy as a neural network that maps “raw” observations to scheduling actions. During training, Reload starts out knowing nothing and gradually learns to make better scheduling decisions through reinforcement, in the form of reward signals for past decisions. Reload leverages Advantage Actor Critic to train the policy network. We evaluate Reload using extensive simulations.</div></div>","PeriodicalId":54775,"journal":{"name":"Journal of Parallel and Distributed Computing","volume":"209 ","pages":"Article 105191"},"PeriodicalIF":4.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous optimization work for All-Reduce operation is to design new algorithms only for different message size and different number of processors, and ignores the optimization that can be achieved by considering the topology. Dragonfly is a popular topology for current and future high-speed interconnection networks. The hierarchical characteristics of dragonfly network can be utilized to effectively reduce hardware overhead while ensuring low end-to-end transmission latency. This paper offers a first attempt to design an efficient All-Reduce algorithm on dragonfly networks, referenced as PAARD. Based on the hierarchical characteristics of dragonfly network, PAARD first proposes an end-to-end solution to alleviate congestion that could remarkably boost performance. We carefully design the algorithm of PAARD to ensure desirable performance with acceptable overhead and guarantee the generality when met marginal cases. Then, to illustrate the effectiveness of PAARD, we analyze the performance of PAARD with the state-of-the-art algorithm, Halving-doubling(HD) algorithm and Ring algorithm. The simulation results demonstrate that in our design the execution time can be improved by 3X for HD and 4.19x for Ring on 256 nodes of a 342-node dragonfly with minimal routing.</div></div>","PeriodicalId":54775,"journal":{"name":"Journal of Parallel and Distributed Computing","volume":"209 ","pages":"Article 105201"},"PeriodicalIF":4.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing studies, which combine blockchain with MEC, often overlook the impact of data offloading on system performance. This paper proposes a Blockchain and MEC-based Secure and Energy-efficient System (BMSES) for sharing Internet of Medical Things (IoMT) data securely among patients and doctors, while optimizing energy consumption through task offloading to MEC servers. Here, the Non-Orthogonal Multiple Access (NOMA) protocol is utilized for efficient channel sharing among multiple users, which offers low cost, reduced latency, and low power consumption. The proposed scheme optimizes energy consumption by efficiently managing task delegation and resource allocation in MEC. Additionally, smart contracts automate blockchain operations, enhancing efficiency and security. The proposed scheme is evaluated in terms of energy consumption, transmission rate, latency, and offloading delay. The results of the experiments show the effectiveness of the proposed scheme compared to state-of-the-art offloading approaches in terms of improving energy efficiency, transmission rate, offloading delay, and latency of the system.</div></div>","PeriodicalId":54775,"journal":{"name":"Journal of Parallel and Distributed Computing","volume":"208 ","pages":"Article 105198"},"PeriodicalIF":4.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are daily communication issues in an Internet of Things network because of the enormous number of connecting nodes. A cloud service is used as a backend by the IoT platform to process data and manage remote control. A successful intrusion detection system (IDS) that can track computer sources and generate data on suspicious or unusual activity is essential for managing the growing complexity of cyberattacks. The security of the IoT network may increasingly become a major issue as IoT technology becomes widely used. Due to the large number and diversity of IoT devices, protecting IoT systems with conventional IDS is difficult. This proposed approach can mitigate the problems of existing studies and achieve better results in the process of detection IoT attacks. Initially, min-max normalization is used to pre-process the inputs to speed up training and improve the efficiency of the proposed model. From the normalized data, a new Adaptive Eagle Cat Optimization (AECO) with unique hunting and search functions is used to select features. Finally, based on the selected features, a Hybrid Deep Convolutional with Capsule Auto Encoder (Hybrid_DCAE) is proposed to classify various intruders, and an Enhanced Gannet Optimization Algorithm (EGOA) is used to fine-tune the parameters for improved system performance.

However, the increasing volume of sensitive data generated by MCS services poses critical challenges in terms of privacy and security, particularly latency-sensitive applications. While some solutions exist, many still lack the scalability, robustness, efficiency, and privacy preservation required by MCS services. This paper proposes a privacy-preserving and secure fog-based MCS (FB-MCS) scheme, comprising a four-tier fog computing architecture that incorporates dynamic lower-tier fog (LTF) and static upper-tier fog (UTF) systems to enable efficient data aggregation, privacy protection, and secure communication. The proposed scheme utilizes secret sharing and homomorphic MAC techniques for efficient and verifiable data aggregation over multi-dimensional data, allowing a data requester to verify the accuracy and integrity of the aggregated results. The scheme employs a lightweight elliptic curve cryptography (ECC) to ensure secure authentication without overburdening resource-constrained devices. An adaptive fog node selection strategy, based on trust and mobility, is proposed for reliable real-time task allocation. Extensive security analysis demonstrates that the scheme not only guarantees privacy preservation, integrity of aggregation results, strong anonymity, un-linkability, traceability, and resistance to well-known attacks but also achieves data confidentiality and unforgeability in the random oracle model under Type I and Type II adversaries, assuming the Computational Diffie-Hellman Problem (CDHP) and Discrete Logarithm Problem (DLP) are intractable.
