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...
PLGAKD: A PUF-based Lightweight Group Authentication and Key Distribution Protocol
Yıldız, Hüsnü; Cenk, Murat; Onur, Ertan (Institute of Electrical and Electronics Engineers (IEEE), 2020-11-01)
Securing Internet of Things (IoT) applications that collect and transport sensitive data by guaranteeing authenticity, integrity, and confidentiality is a critical challenge. Reducing computation and communication overhead...
Density-aware mobile networks: Opportunities and challenges
Mollahasani, Shahram; Eroğlu, Alperen; Demirkol, Ilker; Onur, Ertan (2020-07-05)
We experience a major paradigm shift in mobile networks. The infrastructure of cellular networks is becoming mobile since it is being densified also by using mobile and nomadic small cells to increase coverage and capacity...
DroPPPP: A P4 Approach to Mitigating DoS Attacks in SDN
Simsek, Goksel; Bostan, Hakan; Sarica, Alper Kaan; Sarikaya, Egemen; KELEŞ, AHMET; Angın, Pelin; Alemdar, Hande; Onur, Ertan (2020-01-01)
Software-Defined Networking (SDN) has proven itself a useful technology for establishing and managing configurable, dynamic networks with the rapid deployment of services in the past decade. Despite these advantages, the f...
Content Placement Problem in a Hierarchical Collaborative Caching method for 5G networks (CPP-HCC)
Hassanzadeh, Farnaz; Onur, Ertan (2020-01-01)
The increasing demand for video streaming has imposed tremendous data rates and minimal end-to-end latency requirements on 5G mobile networks. Caching content close to the users is one of the conventional ways to meet thes...
Density-aware cellular coverage control: Interference-based density estimation
Eroğlu, Alperen; Yaman, Okan; Onur, Ertan (2019-12-24)
Dependability-based clustering in mobile ad-hoc networks
Ergenç, Doǧanalp; Eksert, Levent; Onur, Ertan (2019-10-01)
Clustering is an effective solution to handle challenges due to lack of centralized controllers and infrastructure in ad-hoc networks. Clustered network topologies offer better scalability and reliability when compared wit...
Multi-Connectivity Enabled User Association
Simsek, Goksel; Alemdar, Hande; Onur, Ertan (2019-09-01)
This paper focuses on the problem of multi-connectivity enabled downlink user association to maximize the overall throughput in small cell networks, which is an NP-Hard problem. We formulate the problem of user association...
Poster Abstract: iSDR: SDR-in-the-loop Simulation
Ergenc, Doganalp; Onur, Ertan (2019-01-01)
Discrete event network simulators are used to evaluate the performance of a variety of designs in the wireless communication field. They enable researchers to build new network protocols and architectures in a simplified a...
Density-Aware, Energy- and Spectrum-Efficient Small Cell Scheduling
Mollahasani, Shahram; Onur, Ertan (2019-01-01)
Future mobile networks have to be densified by employing small cells to handle the upsurge in traffic load. Although the amount of energy each small cell consumes is low, the total energy consumption of a large-scale netwo...
