Nevertheless, the relatively long lifecycle of line systems (e.g., 10 years), when compared to the shorter lifecycle of line interfaces (e.g., 3 years), means a large fraction of network operators will be looking to leverage these pluggable devices in brownfield deployment scenarios. In this case, the legacy line system can hamper the effectiveness of exploiting the pluggable interfaces. This paper describes a comprehensive framework to estimate the impact of the line system on key network capacity and cost-related metrics when pluggable line interfaces are deployed. The framework is used on a reference optical transport network with growing demand for capacity and assuming a set of possible line systems, including legacy and modern ones. The simulation results highlight that although there are clear benefits in terms of usable capacity when these interfaces are deployed over modern line systems (greenfield scenario), it is still possible to reach competitive capacity figures with legacy line systems (brownfield scenario), particularly via exploiting a trade-off between capacity and the number of line interfaces used as regenerators.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124828304","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}

This paper proposes an online attack detection and network traffic classification system, which combines stream Machine Learning, Deep Learning, and Ensemble Learning technique. Using multiple stages of data analysis, the system can detect the presence of malicious traffic flows and classify them according to the type of attack they represent. Furthermore, we show how to implement this system both in an IoT network and from an ML point of view.

However, attackers can perform traffic-based attacks to reveal the behavior of legitimate users, seriously compromising their privacy. Studies have proposed to obfuscate network traffic to avoid these attacks. However, there is still the challenge of ensuring a trade-off between privacy and network overhead. This work introduces the MITRA method to protect user privacy in smart homes while keeping IoT network overhead low. The method relies on the dummy traffic injection following different levels of obfuscation. The different levels mask network traffic, improving privacy without harming network performance unnecessarily. Results show that the obfuscation of IoT device traffic reduces the traffic identification accuracy by up to 42%.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130091586","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}

However, due to NOMA co-channel interference, the power allocation to large-scale IoT devices becomes critical. The existing convex optimization-based solutions are highly complex hence, it is difficult to find the optimal solution to the resource allocation problem in a highly dynamic environment. Therefore, this work develops an efficient model-free BACNOMA system to assist the base station for complex resource scheduling tasks in a dynamic BAC-NOMA IoT network. More specifically, we jointly optimize the transmit power of downlink IoT users and the reflection coefficient of uplink backscatter devices using a reinforcement learning algorithm, namely, softactor critic. Numerical results show that the proposed algorithm obtained a higher reward and converges to an optimal solution with respect to a large number of iterations. The proposed algorithm increases the sum rate by 57.6% as compared to the conventional optimization (benchmark) approach. Moreover, we show that the proposed algorithm outperforms the conventional BAC-NOMA scheme and BAC with orthogonal multiple access in terms of average sum rate with the increasing number of backscatter devices.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134062709","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 security of GPS is not addressed at the design level, and its implementation is public knowledge, making all GPS-equipped devices susceptible to GPS spoofing attacks. Existing solutions such as cryptography are either not backward compatible or too expensive to implement. Here, we propose an approach without such drawbacks. We present a novel technique to detect GPS spoofing attacks by comparing the final estimated location based on the GPS measurements with that derived by 5G New Radio positioning signals. In case of discrepancy, we detect the GPS spoofing attack and bypass the attacker by replacing the GPS-based localization with 5G-based localization.

This work investigates a deep learning method that tackles the bundle routing problem by taking advantage of the available network metrics and performance data through a graph neural network (GNN). A cognitive routing decision unit is formulated by defining a GNN structure that accepts both edge and node input features, and that is trained with reinforcement learning. The GNN allows the inputs to be permutation invariant and independent of the network size and connectivity. Simulation results demonstrate that the proposed cognitive routing method is able to learn how to optimize the next-hop for each data bundle of a flow to achieve lower end-to-end delivery latency than the standard Contact Graph Routing algorithm. The GNN achieves the optimization by detecting and avoiding the extended wait times caused by both butter congestion and the stall times for the next contact when long link disruptions occur.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115443373","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}

Several works have modelled link stability for data delivery in light of solving the issues originating from unstable vehicle connectivity. However, results have shown that some mobility patterns potentially misguide the uncertainty-based estimation process. We thus propose a region-based connectivity ranking strategy. A fog management approach dynamically defines and supervises regions delimited by vehicles; such regions are mapped over an urban centre. In addition, the model develops a software-defined vehicular network (SDVN) controller to select data from the vehicular heterogeneous network environment through V2X and C-V2X. Our model admits four parameters to describe vehicular connectivity, which evaluates vehicles’ potential for communication and performs dynamic vehicular clustering. The 5G and DSRC heterogeneous networks support a more precise connectivity model for vehicular classification. Simulated analyses allow observing vehicular mobility and connectivity data in real-time scenarios where the management efficiency of vehicular fog regions is assessed in SDVN context.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115845593","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}
