Nonetheless, the PCN topology directly influences the performance, cost, and payment success rate. This paper 1 analyzes the evolution of the Lightning Network topology, which is currently the leading payment channel network. We reconstruct the network graph using real data from a set of channel announcement messages collected between January 2020 and August 2021. Our analysis uses typical graph metrics, such as transitivity, diameter, and degree centrality, to evaluate the state and evolution of the network. The results show a strong trend in resource and connectivity centralization. Only 0.38% of nodes concentrate 50% of the network capacity, exposing a vulnerability to targeted attacks. As with the Bitcoin cryptocurrency, the centralization of the Lightning PCN directly contrasts with the original goal of a fully-decentralized network. Moreover, the low network transitivity compromises channel rebalancing techniques, which contribute to the stability of the system. This trend evidences the need for new attachment policies prioritizing greater network decentralization and robustness.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"44 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":"129527165","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}

They rely on access to location services upon obtaining navigation commands and continually thereafter to enable completely or partially autonomous flight. Global Positioning System (GPS) is not always available, can be spoofed or jammed, and is particularly error-prone in indoor and underground settings. In this article, we present SPIN (Sensor Placement for Indoor Navigation of Drones), a sensor-assisted ranging system for drones that performs in GPS-deficient situations. SPIN employs a novel optimization technique for the deployment of indoor sensors in three-dimensional spaces. SPIN utilizes advancements in Evolutionary Algorithms to compute the smallest number of sensors and their ideal placement in order to minimize deployment costs and localization errors. This challenge is classified as NP-Hard and belongs to the class of Mixed Integer Programming (MIP) problems. SPIN can provide numerous optimal sensor configurations that decrease the number of deployed sensors, enabling autonomous navigation of drones in inside environments at a low cost.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"4 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":"124894882","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 metering data serves for billing, monitoring, and service delivery. However, the interception of a third malicious entity, or the data misuse by the utility could expose customer privacy. The solutions in the literature to protect the privacy of end-users discuss techniques such as data aggregation, homomorphic encryption, and the use of pseudonyms. However, they don’t solve the problem of the curious utility. In this article, we propose the UPriv-AC, a meter data privacy protection mechanism with blind signature and data aggregation. The blind signature allows a certified registry of consumption per user, but preventing the utility from mapping the certified pseudonyms to their respective meters. The proposed aggregation, performed by the meters in a decentralized way, protects users’ privacy from curious aggregators and the user’s identification through the network interface. Hence, our mechanism allows a proper network monitoring, but stopping the utility from building consumer profiles that could reveal users habits and possessions. We analyzed our proposal in comparison with others in the literature. The blind signature proved to be more secure and with 50% lower CPU usage than the partially homomorphic encryption.","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":"127829786","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}

There is no known best algorithm that performs well for all instance realizations of any given traffic restoration problem. In this paper we argue that for a given problem instance, optimum or near-optimum performance can be attained through algorithm selection (AS). The objective is to select from a set of candidate algorithms, the one that performs best for the problem instance. For that, AS is formulated as a learning problem where a Machine-learning algorithm learns the relation between the instance properties and the performance of the candidate algorithms. As case study, the approach is applied for traffic restoration in IP-Optical networks. In these networks, optical failures may affect multiple IP links simultaneously. As a result, the IP layer has to perform traffic restoration by rerouting the affected IP flows. This can be carried out by a hyperheuristic method that performs traffic engineering to minimize the spare capacity utilized for traffic protection. The approach applies AS to choose the best algorithm from a set of heuristics for IP traffic rerouting. Results on selected scenarios show that AS predicts with high precision the heuristic that requires minimum spare capacity.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"247 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":"134272380","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, current state-of-the-art synchronization techniques in space are limited by the Standard Quantum Limit (SQL), thereby limiting progress. Squeezed light, however, offers a pathway to overcome the SQL — an example of the ‘quantum advantage’ offered by non-classical states of light. Here we investigate, for the first time, the practicality of achieving such a quantum advantage between low-Earth-orbit satellites. Among other deployed-platform issues, we pay particular attention to the impact photon loss and pointing error have on the transmitted squeezing level. A key finding of our work is the identification of the conditions under which quantum enhancement, via squeezed light alone, can deliver a factor of two improvement in timing resolution between two satellites. Our work, for the first time, sets the baseline for quantum timing enhancements in satellite networks achievable with current technology. We discuss how advanced quantum techniques beyond squeezed light could improve upon the results presented here.","PeriodicalId":221354,"journal":{"name":"2022 IEEE Latin-American Conference on Communications (LATINCOM)","volume":"44 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":"116176066","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}
