In conventional throughput prediction methods, the future throughput is predicted by learning variations of throughput and some related information such as Received Signal Strength (RSS). On the other hand, the WLAN throughput is highly affected by Channel Occupancy Ratio (COR) due to carrier sense multiple access with collision avoidance. Therefore, this paper proposes simultaneous learning of throughput, RSS, and COR to learn the latent cause of the throughput variation. We compare the prediction accuracy of several prediction models, and it is confirmed that the accuracy is improved by the proposed simultaneous learning regardless of the network structure.","PeriodicalId":410603,"journal":{"name":"2022 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"294 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127561233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We proposed a communication model of the Short Messages Encryption Scheme (SMES) Model with the least additional padding in plain text. We performed a comparative analysis of various existing encryption modes and highlighted the limitations concerning compatibility with SMES. Our communication model utilizes Time of Day (TOD) based loose synchronization intervals in combination with Cipher Feed-Back (CFB) mode of AES encryption. Our evaluation of the proposed scheme shows least processing requirements and overheads in comparison with various other encryption modes.

However, most notable computer vision models are optimized to work under environment with ideal lighting conditions. Real-world scenarios are uncontrolled and it is common to encounter quality and performance deterioration due to challenges in poor lighting, especially related to the amplification of noise signals. Consequently, there is an increase of vision enhancement related works to maintain such models' performances, however there is still a gap in exploring the practical implication that such existing enhancement work has on detection models, as well as the issue and handling of noise signals. Hence, this paper investigates the incorporation of noise information into the enhancement modelling with the specific aim to improve the performance of object recognition. Building upon the zero-reference deep curve estimation (Zero-DCE) approach, a noisy data training strategy is designed in order to introduce noise priors into the curve estimation training to produce better image structure enhancement. Furthermore, the commonly implemented post-process denoising approach is also studied in this work to find out its impact and effectiveness in the context of object detection. Experiments on the ExDark dataset show that the enhanced images produced by the proposed approach is able to improve object detection in low-light images using YOLOv5 with an increase of up to 3% in precision, and comparable performance with significantly more complex state-of-the-art low-light image enhancement models.","PeriodicalId":410603,"journal":{"name":"2022 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"28 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FSO communication system is subject to limitations such as beam dispersion, atmospheric loss, and scintillation. One of the key disadvantages of the FSO system is that its effectiveness is heavily reliant on the conditions of the weather. In this study, we investigate the performance in terms of the signal-to-noise ratio of the FSO system under various channel circumstances and the effects of changing the system's parameters. For instance, as power transmitted, receiver aperture diameter, and laser wavelength, as many researchers use various parameters for their models.

However, designing a robust object tracking method remains a challenging topic due to the tracking challenges such as illumination changes, occlusions, deformations, etc. In this paper, we propose a novel object tracking method that combines attention mechanism and peak sampling to address the problems that arise in most existing object trackers when facing the above challenges. First, an effective hybrid attention mechanism is proposed and then introduced into the model to enhance the tracker's attention to foreground targets. Then, the Maximum peak sampling method is adopted to strengthen the highest peak of the feature response map to highlight the foreground target, which effectively suppresses the interference of target analogues. Finally, a combination of offline training and online learning methods is used to further improve the tracking accuracy and robustness. Experimental results on several standard datasets show that the proposed tracker is able to effectively promote the tracking accuracy and robustness.","PeriodicalId":410603,"journal":{"name":"2022 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116056389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
