These sensors are prone to failures or malfunctions due to various factors, including adverse environmental conditions and aging components within sensors. To mitigate the impact of faulty sensors on system performance, notable research has focused on employing machine-learning techniques to detect faulty sensor data. In this context, due to the scarcity of real faulty data records and challenges in generating them even in controlled environments, researchers often model faulty data to create synthetic datasets containing normal and abnormal data for evaluating fault detection models. Our empirical investigation reveals that the current modeling approach to simulate faulty sensor scenarios does not adequately mirror the complexity of real-world faulty sensor behaviors. Therefore, to improve the efficacy of fault detection algorithms in practical applications, it is imperative to investigate sensor fault models further. To address this gap, we conducted a comparative analysis of existing fault models and proposed a novel composite approach for modeling faulty sensor behaviors that can more effectively capture real-world sensor behaviors. Our focus was to evaluate how different fault models impact the effectiveness of anomaly detection algorithms when tested in real-world scenarios. The evaluation included algorithms trained on synthetic datasets derived from various fault models, assessing their performance in identifying real-world faulty data. We also provide diverse labeled datasets, including normal and abnormal data collected from real-world applications.","PeriodicalId":518960,"journal":{"name":"2024 19th Wireless On-Demand Network Systems and Services Conference (WONS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140529676","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}

Mobility simulation in an integrated space and ground simulation model has thus been identified as one of the key challenges of future research. In this paper we demonstrate that such an integration can be achieved by picking a point in the center of the scenario, the Satellite Observer Position (SOP), and constructing an East-North-Up (ENU) tangential plane through it to arrive at an all-Cartesian coordinate system. Its construction is well-aligned with the needs of Vehicle-to-Satellite (V2S) between-segment channel modeling without sacrificing accuracy for in-segment communication - and which lends itself well to large-scale, high-efficiency simulation of future SAGINs. We back our assumptions with a detailed study on the potential impact of loss of accuracy, demonstrating it to be negligible for most practical purposes in the target application domain. We demonstrate the potential of the presented fully-integrated approach in a small proof-of-concept simulation study where we investigate the impact of small position differences of air/ground nodes in their interplay with the space segment.","PeriodicalId":518960,"journal":{"name":"2024 19th Wireless On-Demand Network Systems and Services Conference (WONS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140529597","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}
