The fifth generation of telecommunication networks comes with various use cases such as Enhanced Mobile Broadband, Ultra-Reliable and Low Latency Communications and Massive Machine Type Communications. These different types of communications have diverse requirements that need to be satisfied while they utilize the same physical infrastructure. By leveraging Software Defined Network (SDN) and Virtual Network Function (VNF) technologies, the 5G network slicing concept can provide end-to-end logical networks on the same physical infrastructure that satisfy the required Quality of Service (QoS) constraints for these communication types. Optimal placement of VNFs on these network slices is still an open problem. Although state-of-the-art research covers the resource allocation of these VNFs, they do not consider optimizing energy consumption under strict security requirements while embedding them into the network. In this paper, we propose a VNF placement strategy using an integer linear programming (ILP) model for 5G network slicing under strict security requirements, which optimizes energy consumption by the core network nodes. Simulation results demonstrate that the proposed model achieves significant power savings over a greedy approach performing VNF placement under the same QoS and security constraints.

Evaluation of priority dependent and time scheduled MAC layer protocols for ad-hoc networks Erdeğer, İsmail; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2015) Ad-hoc networks have very unique features, such as dynamic topologies, relatively limited bandwidth and wireless signal propagation schemes, which present various challenges for wireless communication. In this thesis, control mechanisms for channel access scheduling and topology in ad-hoc networks are evaluated, which utilize the information from two-hop neighborhood to cope with the communication difficulties in ad-hoc networks. Channel assignment is one of the most important topics for ad-hoc networks. Ch...
Mobile multi-access IP: a proposal for mobile multi-access management in future wireless IP networks Altuntas, S; Baykal, Buyurman (Elsevier BV, 2005-03-15) As the wireless networking technologies advance rapidly, providing mobile users with roaming freely in heterogeneous wireless access domains, the need for multi-access arises. This paper introduces the Mobile Multi-Access Management Architecture (MMA-IP) for IP-based future wireless networks. MMA-IP enables mobile users to utilize multiple access domains synchronously and to switch between different access domains. In order to handle multi-access operations, MMA-IP defines a new special mobility agent, call...
Multimedia communication in wireless sensor networks Gurses, E; Akan, OB (2005-07-01) The technological advances in Micro ElectroMechanical Systems (MEMS) and wireless communications have enabled the realization of wireless sensor networks (WSN) comprised of large number of low-cost, low-power multifunctional sensor nodes. These tiny sensor nodes communicate in short distances and collaboratively work toward fulfilling the application specific objectives of WSN. However, realization of wide range of envisioned WSN applications necessitates effective communication protocols which can address ...
Simulation-based VoIP performance evaluation under different traffic and codec conditions Ünlü, Berk; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013) One of today’s most popular multimedia applications that needs more investigation and optimization is Voice over Internet Protocol (VoIP). Simulation tools are essential to test existing network technologies and develop new ones. They are effectively used for network analysis and solving design and optimization problems. The focus of this thesis is an extensive simulation study to evaluate the achieved Quality of Service (QoS) support by VoIP traffic under different network topologies, traffic profiles, cod...
Real-time intrusion detection and prevention system for SDN-based IoT networks Sarıça, Alper Kaan; Angın, Pelin; Department of Computer Engineering (2021-9) The significant advances in wireless networks with the 5G networks have made possible a variety of new IoT use cases. 5G and beyond networks will significantly rely on network virtualization technologies such as SDN and NFV. The prevalence of IoT and the large attack surface it has created calls for SDN-based intelligent security solutions that achieve real-time, automated intrusion detection and mitigation. In this thesis, we propose a real-time intrusion detection and mitigation system for SDN, which aims...
