Firstly, features are extracted from user-item interaction data using the Latent Factor Model (LFM), and an improved Recurrent Neural NetWork (RNN) is used to replace the linear inner product of LFM vectors With non-linearity, Which aims at learning richer features that capture user's short-term interests. Secondly, to avoid single-feature, item information is introduced and the BERT model is used for extracting multi-features. Thirdly, both short-term and long-term interests are considered, and the user's long-term interests are trained by a FeedforWard Neural NetWork (FNN), Which greatly improves the recommendation performance. Experiments designed on multiple real datasets have shown that RN-MHRM effectively improves recommendation performance compared to the baseline model.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"52 1","pages":"235-240"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90661901","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, the high dynamics, limited node energy, and low network density of the FANETs present significant challenges to the FANETs routing protocol, which requires urgent attention in terms of its design. In order to address the issues associated with the routing metric of the FANETs routing protocol, such as the underutilization of link information and the inadequate consideration of the motion of UAVs, which result in high network packet loss rates, unstable routing, and long route reconvergence times, this paper proposes the Predictable Track-based Routing Protocol (PTP). PTP divides the routing protocol into three stages: route establishment, data transmission, and route maintenance. PTP creatively suggests Node Stability Factors (NSF) for UAV in the route establishment stage and develops a Q-learning algorithm to maintain it in accordance with the status of the nodes and nearby nodes. NSF combined the link quality calculated by HELLO messages to generate a link quality based on Q-learning(LQQ) metric. After that, the optimal path from the source node to the destination node is calculated based on this metric. In the data transfer phase, data is transmitted through the routes calculated in the route establishment phase. Create a new HELLO message during the routing maintenance phase to learn the location of the neighbor node and the two-hop neighbor node, predict the node’s future location using the Kalman filter algorithm based on the node’s past location, and react quickly when the link is about to change. Compared to conventional approaches, experiments demonstrate that PTP may successfully raise the successful data delivery rate by 10% to 30%, increase the average route survival time by up to 60%, and cut the average route reconvergence time by up to 80%.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"45 1","pages":"114-119"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82078062","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}

For this problem, our previous work addressed the issue of the user’s initial and final location leakage and provided a strong utility guarantee in the RoD system. Further, the trajectory information is also important in the RoD system, it could contain a lot of private information about the user, such as health or identity, so it’s important to publish a distorted and productive trajectory. For this purpose, in this paper, we provide our trajectory protection method with pricing awareness based on previous work; the method uses supply and demand density function to guide the division of a discrete spatial grid, then uses the Markov chain to generate distorted trajectories on the grid to ensure trajectory continuity, and makes corresponding defenses against several attacks, such as Bayesian. The experiment results on real-world datasets prove the validity and robustness of the method.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"60 1","pages":"37-45"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85627610","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}

Failure to handle hand-off properly may result in delays, data loss, or service interruption during service switching. Therefore, optimizing the hand-off process to ensure service continuity and satisfactory user experience is a significant challenge in the design of edge computing systems. In this paper, we propose a resource reservation algorithm that reserves a portion of computing resources in each base station to meet quality of service (QoS) requirements during service switching. We use an LSTM model to predict the number of new and existing users at a future time point to provide decision guidance for the resource reservation algorithm. Extensive simulation experiments demonstrate that the proposed algorithm outperforms the benchmark algorithms in a variety of environmental conditions.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"99 1","pages":"330-335"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73451820","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}

The current SAR ship detection method based on deep learning (DL) is difficult to more effectively fuse complex features, which leads to low detection accuracy of target ships and even missed or false detections. In order to solve this problem, this paper proposes an improved YOLOX-based SAR image ship detection method, called NAS-YOLOX. Based on the YOLOX algorithm, path aggregation feature pyramid network (PAFPN) is replaced by a neural architecture search - feature fusion network (NAS-FPN) to enhance the cross-scale fusion ability of the proposed model. And a dilated convolution feature enhancement module (DFEM) is also designed and embedded into the backbone network to boost the network receptive field and the ability to extract target information. Furthermore, a multi-scale channel-spatial attention (MCSA) is proposed to improve the attention to key areas of the ship. The experimental results on the HRSID public data set show that the AP0.5 of NAS-YOLOX is 6.3% higher than that of the YOLOX model. Compared with other ten mainstream target detection algorithms, NAS-YOLOX has also achieved excellent detection result.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"10 1","pages":"126-131"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86147868","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}

Many of these systems used secure protocols like end-to-end encryption to ensure strong security features such as “future secrecy” for one-to-one communication. However, the majority of them rely on centralized servers owned by big IT companies, which allows them to use their users’ personal data. Also it allows the government to track and regulate their citizens’ activities, which poses significant threats to “digital freedom”. Also, these systems have failed to achieve security attributes like confidentiality, integrity, privacy, and future secrecy for group communications. In this paper, we present a novel blockchain-based secure messaging system named Quarks that overcomes the security pitfalls of the existing systems and eliminates the centralized control. We have analyzed our design of the system with security models and definitions from existing literature to demonstrate the system’s reliability and usability. We have developed a Proof of Concept (PoC) of the Quarks system leveraging Distributed Ledger Technology (DLT), and conducted load testing on that. We noticed that our PoC system achieves all the desired attributes that are prevalent in a traditional centralized messaging scheme despite the limited capacity of the development and testing environment. Therefore, this assures us the applicability of such systems in near future if scaled up properly.","PeriodicalId":56007,"journal":{"name":"Journal of Cloud Computing-Advances Systems and Applications","volume":"2 1","pages":"268-274"},"PeriodicalIF":4.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87916950","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}
