The evolution of the Internet of things and information communication services introduces new demands in the 5G area. New types of services and use cases such as massive machine-type communication applications, enhanced mobile broadband and ultra-reliable low-latency services will be created in the coming years. These new services and applications will significantly increase energy consumption. In this thesis, we propose a solution for dynamically configuring the radio access technology by employing cloud radio access networks in 5G to conserve energy. Depending on user locations, remote radio unit (RRU) locations and user demands, the communication stack on the RRU is dynamically determined. While some of the RRUs are turned off in this solution, others are configured to run a protocol stack that consumes less energy while meeting user demands. We define this approach as an optimization problem in this thesis and solve it using the state-of-the-art optimization tools. We show that significant amounts of energy can be conserved by employing this approach.

Modelling mobile telecommunications services for forecasting purposes : a cross - country analysis Eser, Eren; Eren, Pekin Erhan; Department of Information Systems (2012) Mobile telecommunications industry has experienced high growth rates for the recent 30 years. Accordingly, forecasting the future of mobile telecommunications services is important not only for mobile operators but also for all stakeholders in this industry ranging from handset manufacturers to vendors. In this thesis, the diffusion of mobile telecommunications services in 20 countries from different regions around the world is examined for the period of 1981 to 2010 with special emphasis on Turkey, in orde...
An Experimental Comparison of Messaging Protocols MQTT and COAP Çoban, Hasan Faruk; Betin Can, Aysu; Department of Information Systems (2017) As the attention towards to Internet of Things (IoT) increases recently, the need for the infrastructure that carries the communication between nodes, which have limited resources, also increases. The network beneath applications has direct effect on resilience of IoT environments. Due to the advances on mobile devices in terms of more powerful hardware, developers focused on mobile applications. However, solid network structures are needed for these applications. To match these needs several protocols are ...
Analyzing enhanced real-time uplink scheduling algorithm in 3GPP LTE-advanced networks using multimedia systems Deebak, B. D.; Ever, Enver; Al-Turjman, Fadi (2018-10-01) Third Generation Partnership Project (3GPP) standardizes the Long-Term Evolution (LTE) to improve the quality of service in modern communication systems using 3GPP LTE-advanced (LTE-A) networks. As this technology is converging with modern devices, efficient resource allocation schemes are essential for minimization of the communication delay for the sensitive real-time devices. To achieve the demands of latest technologies, this paper proposes two novel mechanisms, enhanced real-time polling system with co...
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...
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 with 5G and beyond networks, which will primarily rely on software-defined networking (SDN) and network functions virtualization for achieving the promised quality of service. The prevalence of IoT and the large attack surface that it has created calls for SDN-based intelligent security solut...
