Adaptive domain-specific service monitoring
Ünsal, Arda Ahmet (2014-01)We propose an adaptive and domain-specific service monitoring approach to detect partner service errors in a cost-effective manner. Hereby, we not only consider generic errors such as file not found or connection timed ... -
Analysis of ALTO protocol over P2P networks
Kökten, Koray (2012-10)Currently, for distributed applications such as Peer-to-Peer (P2P) and Content Delivery Networks (CDNs), the most important challenge is to determine the optimal peer or node selection process, since it sometimes causes ... -
Application-based scheduling for indoor femtocell networks
Mungan, Devin (2013-01)This thesis is concerned with designing a QoS-enabled, application-based scheduler for indoor femtocell networks. For this purpose, a novel scheduler is proposed which takes into account the quality of service (QoS) ... -

The costs and benefits of turning data into information using big data systems
Koca, Melih (2014-08)This thesis explains problems of and solutions for storing and processing big volumes and streaming types of data in a cost-e ective way for enterprise companies. There are several problems like operational, infrastructural ... -
Experimental QOS-based comparison of olsr and B.A.T.M.A.N. mesh routing algorithms for multimedia home networks
Ulusoy, Sırrı Erdem (2013-08)Wireless Mesh Networks (WMNs) allow communication of two nodes via a multi-hop route, without the need for an infrastructure such as base stations. Routing has been a fundamental issue for this type of communication networks. ... -
Fall detection for elderly people using depth video data obtained by kinect
Davari, Amir Abbas (2013-08)Automatic detection of unusual events such as falls is very important especially for elderly people living alone. Real-time detection of these events can reduce the health risks associated with a fall. There has been a ... -
Fault masking as a service
Gülcü, Koray (2013-01)In service-oriented architectures, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable due to system and/or network faults, leading to an increased ... -
Improving models for model-based testing based on exploratory testing
Gebizli, Ceren Şahin (2014-08)Model bazlı test, test edilen sistemin modelleri sayesinde otomatik olarak test senaryoları oluşturulmasını sağlar. Bu modellerin doğruluğu ve tamlığı oluşturulan test senaryolarının etkinliğini belirler. Genelde manuel ... -
Information theoretical performance analysis and optimization of underwater acoustic communication systems
Nouri, Hatef (2013-08)Underwater wireless communication is a rapidly growing field of research and engineering as its applications, which were once exclusively military, are extending into commercial fields. The need for underwater wireless ... -
Joint frequency allocation and power control for minimum downlink interference in femtocellular networks
Ferazoğlu, Gülden (2013-01)Due to the fact that the most of data services and more than half of calls are requested indoors, it has been dramatically important and even a must for cellular operators to provide more than adequate indoor coverage. ... -
Modeling of RF energy harvesting and energy consumption system for low power wireless sensor networks
Amjad, Osama (2017-01)Recently, with the advancement of technology, there has been a rapid growth of low power wireless devices, such as wireless sensor networks (WSNs) and Internet of Things (IoT). Therefore, the energy requirement for perpetual ... -

Multiple-description coded streaming video multicast over software-defined networs
Noghani, Kyoomars Alızadeh (2014-08)Video has become one of the most prominent applications of the Internet. Many of the video streaming applications involve the distribution of content from a CDN source to a large population of interested clients. However, ... -
Optimization and analysis of WLAN RF energy harvesting system architecture for low power wireless applications
Munır, Syeda Wajıha (2017-01)The presented work proposes a radio frequency (RF) energy harvesting circuit design, which scavenges energy from WLAN dual frequency band. In comparison to other available sources for energy scavenging, e.g. solar, wind ... -
P2P live scalable video streaming with ALTO service
Kırkgül, İsmail Serkan (2012-10)It has been measured that, as high as 80% of the average Internet traffic is now from peer-to-peer (P2P) applications, and upwards of 90% during peak hours. These results tell us that a significant portion of the traffic ... -
Performance analysis and optimization of relay-assisted free space optical communication systems
Kashani, Mohammadreza Amini (2012-07)Free-space optical (FSO) communication has received an increasing attention in recent years with their ability to achieve ultra-high data rates (at the order of multiple gigabits per second) over unlicensed optical spectrum. ... -
