This work proposes a novel solution to these constraints using mobile edge computing (MEC). We present the Dependent Task-Offloading technique (DTOS), a deep reinforcement learning-based technique for optimizing task offloading to numerous heterogeneous edge servers in intelligent prosthesis applications. By expressing the task offloading problem as a Markov decision process, DTOS addresses the dual challenge of lowering network service latency and power utilisation. DTOS employs a weighted sum optimisation method in this approach to find the best policy. The technique uses parallel deep neural networks (DNNs), which not only create offloading possibilities but also cache the most successful options for further iterations. Furthermore, the DTOS modifies DNN variables using a prioritized experience replay method, which improves learning by focusing on valuable experiences. The use of DTOS in a real-world MEC scenario, where a deep learning-based movement intent detection algorithm is deployed on intelligent prostheses, demonstrates its applicability and effectiveness. The experimental results show that DTOS consistently makes optimal decisions in work offloading and planning, demonstrating its potential to improve the operational efficiency of intelligent prostheses significantly. Thus, the study introduces a novel approach that combines the characteristics of deep reinforcement learning with MEC, demonstrating a substantial development in the field of intelligent prostheses through optimal task offloading and reduced resource usage.","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":"19 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139760771","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}

However, as the number of vehicles on highways increases, ensuring reliable communication between them has become a significant challenge. To address this issue, this paper proposes a novel approach that combines Non-Orthogonal Multiple Access (NOMA) with a time-optimized multitask offloading model based on Optimal Stopping Theory (OST) principles. NOMA-OST is a promising technology that can address the high volume of multiple access and the need for reliable communication in IoV. A NOMA-OST-based IoV system is proposed to meet the Vehicle-to-Vehicle (V2V) communication requirements. This approach optimizes joint task offloading and resource allocation for multiple users, tasks, and servers. NOMA enables efficient resource sharing by accommodating multiple devices, whereas OST ensures timely and intelligent task offloading decisions, resulting in improved reliability and efficiency in V2V communication within IoV, making it a highly innovative and technically robust solution. It suggests a low-complexity sub-optimal matching approach for sub-channel allocation to increase the effectiveness of offloading. Simulation results show that NOMA with OST significantly improves the system’s energy efficiency (EE) and reduces computation time. The approach also enhances the effectiveness of task offloading and resource allocation, leading to better overall system performance. The performance of NOMA with OST under V2V communication requirements in IoV is significantly improved compared to traditional orthogonal multiaccess methods. Overall, NOMA with OST is a promising technology that can address the high reliability of V2V communication requirements in IoV. It can improve system performance, and energy efficiency and reduce computation time, making it a valuable technology for IoV applications.","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":"33 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139760788","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}

Edge computing bridges mobile devices and the cloud, giving mobile devices access to computing, memory, and communication capabilities via vehicular ad hoc networks (VANET). VANET is a time-constrained technology that can handle requests from vehicles in a shorter amount of time. The most well-known problems with edge computing and VANET are latency and delay. Any congestion or ineffectiveness in this network can result in latency, which affects its overall efficiency. The data processing in smart city affected by latency can produce irregular decision making. Some data, like traffics, congestions needs to be addressed in time. Delay decision making can make application failure and results in wrong information processing. In this study, we created a probability-based hybrid Whale -Dragonfly Optimization (p–H-WDFOA) edge computing model for smart urban vehicle transportation that lowers the delay and latency of edge computing to address such issues. The 5G localized Multi-Access Edge Computing (MEC) servers were additionally employed, significantly reducing the wait and the latency to enhance the edge technology resources and meet the latency and Quality of Service (QoS) criteria. Compared to an experiment employing a pure cloud computing architecture, we reduced data latency by 20%. We also reduced processing time by 35% compared to cloud computing architecture.

As a brand-new international trade, cross-border e-commerce offers numerous benefits, including increased accessibility. Even though cross-border e-commerce has a bright future, managing the global supply chain is crucial to surviving the competitive pressure and growing steadily. Traditional purchase volume forecasting uses time-series data and a straightforward prediction methodology. Numerous customer consumption habits, including the number of products or services, product collections, and taxpayer subsidies, influence the platform's sale quantity. The use of the EC supply chain has expanded significantly in the past few years because of the economy's recent rapid growth. The proposed method develops a Short-Term Demand-based Deep Neural Network and Cold Supply Chain Optimization method for predicting commodity purchase volume. The deep neural network technique suggests a cold supply chain demand forecasting framework centred on multilayer Bayesian networks (BNN) to forecast the short-term demand for e-commerce goods. The cold supply chain (CS) optimisation method determines the optimised management inventory.

This network facilitates the transmission of real-time patient data, sensed by resource-constrained biosensors, to the end user through an open communication channel. Thus, any modification or alteration in such sensed physiological data leads to the wrong diagnosis which may put the life of the patient in danger. Therefore, among many challenges in WMSN, the security is most essential requirement that needs to be addressed. Hence, to maintain the security and privacy of sensitive medical data, this article proposed a lightweight mutual authentication and key agreement (AKA) scheme using Physical Unclonable Functions (PUFs) enabled sensor nodes. Moreover, to make the WMSN more secure and reliable, the physiological data like the electrocardiogram (ECG) of the patients are also considered. In order to establish its accuracy and security, the scheme undergoes validation through the Real or Random (RoR) Model and is further confirmed through simulation using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. A thorough examination encompassing security, performance, and a comparative assessment with existing related schemes illustrates that the proposed scheme not only exhibits superior resistance to well-known attacks in comparison to others but also upholds a cost-effective strategy at the sensor node, specifically, a reduction of 35.71% in computational cost and 49.12% in communication cost.","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":"3 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139666826","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}

This approach is critical to handling large numbers of requests. To enhance caching efficiency, federated deep reinforcement learning (FDRL) is widely used to adjust caching policies. Nonetheless, for improved adaptability in dynamic scenarios, FDRL generally demands extended and online deep training, incurring a notable energy overhead when contrasted with rule-based approaches. With the aim of achieving a harmony between caching efficiency and training energy expenditure, we integrate a content request latency model, a deep reinforcement learning model based on markov decision processes (MDP), and a two-stage training energy consumption model. Together, these components define a new average delay and training energy gain (ADTEG) challenge. To address this challenge, we put forth a innovative dynamic federated optimization strategy. This approach refines the pre-training phase through the use of cluster-based strategies and parameter transfer methodologies. The online training phase is improved through a dynamic federated framework and an adaptive local iteration count.

As businesses move beyond smart manufacturing, we describe an automated racking assessment method utilizing an integrated framework, MobileNetV2-you only look once (YOLOv5). The proposed method examines the automated pallet tracking system and detects multiple damages based on edge platforms during pallet racking. It employs YOLOv5 in conjunction with the Block Development Mechanism (BDM), which detects defective pallet racks. We propose a device that attaches to the moveable cage of the forklift truck and provides adequate coverage for the neighboring racks. Also, we classify any damage as significant or minor so that floor supervisors can decide whether a replacement is necessary immediately in each circumstance. Instead of conducting annual or quarterly racking inspections, this would give the racking industry a way to continuously monitor the racking, creating a more secure workplace environment.

To deploy the WSN in a larger area, for sensing the environment, the accurate location of the node is a prerequisite. Owing to these traits, the WSN has been effectively implemented with devices. Using various localization techniques, the information related to node location is obtained for unknown nodes. Recently, node localization has employed the standard bio-inspired algorithm to sustain the fast convergence ability of WSN applications. Thus, this paper aims to develop a new hybrid optimization algorithm for solving the node localization problems among the unknown nodes in WSN. This hybrid optimization scheme is developed with two efficient heuristic strategies of Black Widow Optimization (BWO) and Honey Badger Algorithm (HBA), named as Hybridized Black Widow-Honey Badger Optimization (HBW-HBO) to achieve the objective of the framework. The main objective of the developed heuristic-based node localization framework is to minimize the localization error between the actual locations and detected locations of all nodes in WSN. For validating the developed heuristic-based node localization scheme in WSN, it is compared with different existing optimization strategies using different measures.

The goal is to address the challenges related to latency, energy consumption, and payment cost requirements. The approach considers both moving and parked vehicles as fog nodes, which can assist in offloading computational tasks. However, as the number of vehicles increases, the action space for each agent grows exponentially, posing a challenge for decentralised decision-making. The dynamic nature of vehicular mobility further complicates the network dynamics, requiring joint cooperative behaviour from the learning agents to achieve convergence. The traditional deep reinforcement learning (DRL) approach for offloading in IoVs treats each agent as an independent learner. It ignores the actions of other agents during the training process. This paper utilises a cooperative three-layer decentralised architecture called Vehicle-Assisted Multi-Access Edge Computing (VMEC) to overcome this limitation. The VMEC network consists of three layers: the fog, cloudlet, and cloud layers. In the fog layer, vehicles within associated Roadside Units (RSUs) and neighbouring RSUs participate as fog nodes. The middle layer comprises Mobile Edge Computing (MEC) servers, while the top layer represents the cloud infrastructure. To address the dynamic task offloading problem in VMEC, the paper proposes using a Decentralized Framework of Task and Computational Offloading (DFTCO), which utilises the strength of MADRL and NOMA techniques. This approach considers multiple agents making offloading decisions simultaneously and aims to find the optimal matching between tasks and available resources.","PeriodicalId":54817,"journal":{"name":"Journal of Grid Computing","volume":"5 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139560757","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}
