Dynamic Resource Management in Next Generation Networks based on Deep Q Learning Aslan, Aysun; Bal Bozkurt, Gülce; Toker, Cenk (Institute of Electrical and Electronics Engineers (IEEE); 2021-1-07) In next generation networks, with the increasing number of diverse mobile network service types, a major challenge lies in how to manage and support all mobile service users who have different Quality of Service (QoS) requ...
Covert Channel Detection Using Machine Learning Çavuşoğlu, İmge Gamze; Alemdar, Hande; Onur, Ertan (2021-01-07) A covert channel is a communication method that misuses legitimate resources to bypass intrusion detection systems. They can be used to do illegal work like leaking classified (or sensitive) data or sending commands to mal...
Forecasting directional movement of Forex data using LSTM with technical and macroeconomic indicators Yildirim, Deniz Can; Toroslu, İsmail Hakkı; Fiore, Ugo (2021-01-01) Forex (foreign exchange) is a special financial market that entails both high risks and high profit opportunities for traders. It is also a very simple market since traders can profit by just predicting the direction of th...
MDP based Decision Support for Earthquake Damaged Distribution System Restoration Arpalı, Onur Yigit; Yılmaz, Uğur Can; Aydın Göl, Ebru; Güldür Erkal, Burcu; Göl, Murat (2020-12-16) As the society becomes more dependent on the presence of electricity, the resilience of the power systems gains more importance. This paper develops a decision support method for distribution system operators to restore el...
Named entity recognition on morphologically rich language: exploring the performance of BERT with varying training levels Kılıç, Yüksel Pelin; Dinç, Duygu; Karagöz, Pınar (null; 2020-12-13)
Dynamic Resource Management in Next Generation Networks with Dense User Traffic Aslan, Aysun; Bal Bozkurt, Gülce; Toker, Cenk (IEEE; 2020-12-04) With the era of the fifth generation (5G) networks, supporting all mobile service users who have different Quality of Service (QoS) requirements becomes the main challenge. To manage and satisfy the heterogeneous requireme...
Explainable Security in SDN-Based IoT Networks Sarica, Alper Kaan; Angın, Pelin (2020-12-01) The significant advances in wireless networks in the past decade have made a variety of Internet of Things (IoT) use cases possible, greatly facilitating many operations in our daily lives. IoT is only expected to grow wit...
Realistic Lighting for Interactive Applications Using Semi-Dynamic Light Maps Öztürk, Bekir; Akyüz, Ahmet Oğuz (2020-12-01) Light mapping is a technique that works by precomputing the lighting of a scene to speed up expensive lighting calculations at run-time. It is a commonly employed technique for computer games, in particular mobile games, d...
A Novel SDN Dataset for Intrusion Detection in IoT Networks Sarica, Alper Kaan; Angın, Pelin (2020-11-04) The number of Internet of Things (IoT) devices and the use cases they aim to support have increased sharply in the past decade with the rapid developments in wireless networking infrastructures. Despite many advantages, th...
Supervised approaches for explicit search result diversification Yigit-Sert, Sevgi; Altıngövde, İsmail Sengör; Macdonald, Craig; Ounis, Iadh; Ulusoy, Özgür (Elsevier BV, 2020-11-01) Diversification of web search results aims to promote documents with diverse content (i.e., covering different aspects of a query) to the top-ranked positions, to satisfy more users, enhance fairness and reduce bias. In th...
Energy-efficient and fault-tolerant drone-BS placement in heterogeneous wireless sensor networks Deniz, Fatih; Bagci, Hakki; KÖRPEOĞLU, İBRAHİM; Yazıcı, Adnan (2020-11-01) This paper introduces a distributed and energy-aware algorithm, called Minimum Drone Placement (MDP) algorithm, to determine the minimum number of base stations mounted on resource-rich Unmanned Aerial Vehicles (UAV-BS), c...
