In particular, analyzing <i>hotspots</i>, i.e., areas presenting an increased popularity at certain times, is crucial for adequate planning and management operations. Yet, despite its importance, we lack today a precise definition of the term <i>hotspot</i> in the community. The essence of this contribution is based on a unique mobile phone dataset collected by a French mobile operator in the city of Paris. In this work, we propose a new definition for the hotspot concept while highlighting the major weaknesses of the literature. Moreover, we provide an extensive benchmarking for the hotspot forecasting problem. Our results show that Long Short-Term Memory (LSTM) gives the best performance for the hotspot prediction problem, and we consider it for a Robotic Aerial Base Station (RABS) deployment application. In order to minimize the RABSs’ travel distances, we mathematically model the problem and introduce a greedy and Particle Swarm Optimization (PSO) algorithms to solve it. The results in terms of coverage ratio and travel distance showcase the difference between a prediction-based approach and a non-prediction-based approach.</p></div>","PeriodicalId":50761,"journal":{"name":"Annals of Telecommunications","volume":"81 1-2","pages":"133 - 148"},"PeriodicalIF":2.2,"publicationDate":"2026-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147617982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are also prime attack targets for malicious parties. Although there has been an extensive exploration of attack detection methods rooted in machine learning, such approaches necessitate high processing overhead, which is ill-suited for devices of modest processing capabilities. Furthermore, machine learning algorithms are opaque black boxes. Therefore, we present a novel hybrid approach to detect distributed denial-of-service attacks using fuzzy cognitive maps paired with machine learning feature selection. Our approach incorporates contextual information (features) drawn from network packets. We utilize feature selection methods to compute the weights of the features. The weights capture the influence of each input feature on the target output feature that determines the classification of any packet as malicious or benign. The features and weights are used to construct a fuzzy cognitive map for each type of attack. The fuzzy cognitive map is then used to train and test the dataset. We also auto-compute a threshold value that allows our model to classify a packet as malicious or benign. Our model performs best using the weights computed by two particular statistical feature selection algorithms, namely, SelectKBest-Classification and SelectKBest Chi-squared, combined with FCM. Our experiments show that this hybrid approach is simple, reliable, and transparent with a low memory footprint, and therefore well-suited for devices with limited resources.</p></div>","PeriodicalId":50761,"journal":{"name":"Annals of Telecommunications","volume":"80 -","pages":"1071 - 1094"},"PeriodicalIF":2.2,"publicationDate":"2025-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12243-025-01130-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its numerous benefits, the ease of duplication, fraud, and illegal resale poses several issues in the industry, which can adversely impact event organizers and legitimate buyers. Furthermore, security breaches could compromise buyers’ personal and financial information. An e-ticketing system based on blockchain is implemented, mainly designed for managing raffles. This system issues e-tickets recorded in encrypted form in a blockchain with multiple blocks. The system digitally signs each ticket, links it to the buyer, records the data on-chain, and conducts draws using secure cryptographic randomness. At the end of the process, the system provides an option to download an audit chain that facilitates the validation and audit of the draws. We used the agile Scrum methodology and Java to develop the e-ticket system, implementing the blockchain with a PostgreSQL database and a custom hash function. We store each block in an unstructured JSON-type field. To optimize response times in processing the proof-of-work (PoW) blockchain, a Java socket server was implemented to manage mining pools and distribute the load among miners. We organized the load into groups by applying the <i>K</i>-means algorithm to historical performance data. This classification enabled the formation of efficient groups that accelerated PoW resolution, enhancing the security and performance of raffle creation, signing, and execution, particularly under increased hash difficulty. Each miner received rewards based on their contribution, fostering community participation and encouraging continuous improvement in individual performance.

While informal analysis demonstrates resilience to common threats like replay and impersonation, the random oracle model formally proves security. The robustness of the protocol against a variety of active attacks is confirmed through additional verification using the AVISPA tool. Further performance analysis shows that the suggested method clearly improves post-quantum security and computational efficiency when compared to current authenticated key agreement schemes, while facing slightly higher communication costs to ensure stronger security.
