Widespread deployment of new generation high-speed networks, developments in large capacity DWDM technologies, and continuous demand for increasingly resilient global Internet services necessitates a revision on optical transport networks. Considered to be one of the most promising recent phenomena in that sense, OTN is evolving to become a major core switching platform. In this thesis, we briefly present the progress in optical transport networking from hardware architecture and software hierarchy points of views. Then, trends in protection switching are pointed out through a peculiar taxonomy on computational, topological, and efficiency aspects. Finally, an autonomous, low complexity and inter-disciplinary (incorporating automatic protection switching of optical networks with distance vector routing of mobile ad-hoc networks) lightpath recovery algorithm is offered based on time-zone awareness of OTN nodes to fulfill the basic requirements expected from mesh optical networks. The proposed algorithm is evaluated with simulation in comparison to two well-known algorithms.

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...
GreenSlice: An Energy-Efficient Secure Network Slicing Framework
Akin, Ozan; Gulmez, Umut Can; Sazak, Ozan; Yagmur, Osman Ufuk; Angın, Pelin (2022-02-01)
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 ...
Adaptable Safety and Security in V2X Systems
VİLLARREAL VASQUEZ, Miguel; BHARGAVA, Bharat; Angın, Pelin (2017-06-30)
With the advances in the areas of mobile computing and wireless communications, V2X systems have become a promising technology enabling deployment of applications providing road safety, traffic efficiency and infotainment. Due to their increasing popularity, V2X networks have become a major target for attackers, making them vulnerable to security threats and network conditions, and thus affecting the safety of passengers, vehicles and roads. Existing research in V2X does not effectively address the safety, ...
Scheduling algorithms for wireless cdma networks
Hakyemez, Serkan Ender; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2007)
In recent years the need for multimedia packet data services in wireless networks has grown rapidly. To overcome that need third generation (3G) mobile services have been proposed. The fast growing demands multimedia services in 3G services brought the need for higher capacity. As a result of this, the improvement on throughput, traffic serving performance has become necessary in 3G systems. Code division multiple access (CDMA) technique is one of the most important 3G wireless mobile techniques that has be...
Design of log-periodic dipole array feed and wide band reflector antenna system
Tanyer, Fatma Müge; Tanyer, Fatma Müge; Department of Electrical and Electronics Engineering (2005)
The introduction of broadband systems to communication and radar technologies has demanded the design of broadband antennas. In this thesis, broadband log-periodic dipole antennas and reflector antennas are investigated. A dual polarized log-periodic dipole antenna and a reflector antenna are designed and analyzed within the frequency band of 0.4-18 GHz. Basic theory and calculations about mutual coupling between the linear antenna elements are given. The currents at the bases of dipoles of the log-periodic...
