In\u0000practice, DTs of physical devices, such as mobile users (MUs), are commonly\u0000deployed in multi-access edge computing (MEC) networks for the sake of reducing\u0000latency. To ensure the accuracy and fidelity of DTs, it is essential for MUs to\u0000regularly synchronize their status with their DTs. However, MU mobility\u0000introduces significant challenges to DT synchronization. Firstly, MU mobility\u0000triggers DT migration which could cause synchronization failures. Secondly, MUs\u0000require frequent synchronization with their DTs to ensure DT fidelity.\u0000Nonetheless, DT migration among MEC servers, caused by MU mobility, may occur\u0000infrequently. Accordingly, we propose a two-timescale DT synchronization and\u0000migration framework with reliability consideration by establishing a non-convex\u0000stochastic problem to minimize the long-term average energy consumption of MUs.\u0000We use Lyapunov theory to convert the reliability constraints and reformulate\u0000the new problem as a partially observable Markov decision-making process\u0000(POMDP). Furthermore, we develop a heterogeneous agent proximal policy\u0000optimization with Beta distribution (Beta-HAPPO) method to solve it. Numerical\u0000results show that our proposed Beta-HAPPO method achieves significant\u0000improvements in energy savings when compared with other benchmarks.","PeriodicalId":501280,"journal":{"name":"arXiv - CS - Networking and Internet Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183940","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}

While deploying more satellites offers a short-term fix,\u0000designing higher-performance satellites with enhanced transmission capabilities\u0000provides a more sustainable solution. Achieving the necessary high capacity\u0000requires interconnecting multiple modem banks within a satellite payload.\u0000However, there is a notable gap in research on internal packet routing within\u0000extremely high-throughput satellites. To address this, we propose a real-time\u0000optimal flow allocation and priority queue scheduling method using online\u0000convex optimization-based model predictive control. We model the problem as a\u0000multi-commodity flow instance and employ an online interior-point method to\u0000solve the routing and scheduling optimization iteratively. This approach\u0000minimizes packet loss and supports real-time rerouting with low computational\u0000overhead.

Acting like moving cameras, EO satellites are formed in\u0000constellations with different missions and priorities, and capture vast data\u0000that needs to be transmitted to the ground for processing. However, EO\u0000satellites have very limited downlink communication capability, limited by\u0000transmission bandwidth, number and location of ground stations, and small\u0000transmission windows due to high velocity satellite movement. To optimize\u0000resource utilization, EO constellations are expected to share communication\u0000spectrum and ground stations for maximum communication efficiency. In this paper, we investigate a new attack surface exposed by resource\u0000competition in EO constellations, targeting the delay or drop of Earth\u0000monitoring data using legitimate EO services. Specifically, an attacker can\u0000inject high-priority requests to temporarily preempt low-priority data\u0000transmission windows. Furthermore, we show that by utilizing predictable\u0000satellite dynamics, an attacker can intelligently target critical data from\u0000low-priority satellites, either delaying its delivery or irreversibly dropping\u0000the data. We formulate two attacks, the data delay attack and the data overflow\u0000attack, design algorithms to assist attackers in devising attack strategies,\u0000and analyze their feasibility or optimality in typical scenarios. We then\u0000conduct trace-driven simulations using real-world satellite images and orbit\u0000data to evaluate the success probability of launching these attacks under\u0000realistic satellite communication settings. We also discuss possible defenses\u0000against these attacks.","PeriodicalId":501280,"journal":{"name":"arXiv - CS - Networking and Internet Architecture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183742","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}

By incorporating word2vec embeddings, this work significantly mitigates\u0000the dimensionality curse often associated with traditional one-hot encoding,\u0000thereby enhancing the training effectiveness of the model. Experimental results\u0000demonstrate that word2vec encoding captures semantic relationships between\u0000field values more effectively than one-hot encoding, improving the accuracy and\u0000naturalness of the generated data.

Future\u0000research could focus on optimizing the integration of GNNs and GANs, reducing\u0000computational costs, and validating the model's generalizability on larger\u0000datasets.
