The problem of providing Quality of Service (QoS) in the Internet has been an extremely active area of research and various mechanisms have been proposed related to this subject. Developing network applications have requirements such as bounded delay, jitter, minimum bandwidth and maximum loss rate. There is also a need to support large bandwidth networks because of growing link speeds. Previous QoS efforts did not fully satisfy all these needs of future networks but more recent approaches aim to be both scalable and rich in the provision of guaranteed services. Consequently core-stateless systems received much attention in recent years because of their scalability in supporting per-flow QoS. The property of not maintaining any per-flow state in the core routers is known as being core-stateless. In this thesis study, the need for core-stateless network architectures is pointed out and a literature survey about these schemes is carried out. Core-Stateless Guaranteed Fair (CSGF) network architecture, which provides deterministic fairness guarantees in a work-conserving manner, is selected and evaluated. Simulation studies about stateful Virtual Clock (VC) algorithm and CSGF’s sub-protocols Core-Stateless Virtual Clock (CSVC), Core-Stateless Guaranteed Throughput (CSGT) and Core-Stateless Guaranteed Fairness (CSGF) are presented. Finally, the deficiencies in fairness of CSGF are demonstrated.

A new approach for the scalable intrusion detection in high-speed networks
Şahin, Ümit Burak; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2007)
As the networks become faster and faster, the emerging requirement is to improve the performance of the Intrusion Detection and Prevention Systems (IDPS) to keep up with the increased network throughput. In high speed networks, it is very difficult for the IDPS to process all the packets. Since the throughput of IDPS is not improved as fast as the throughput of the switches and routers, it is necessary to develop new detection techniques other than traditional techniques. In this thesis we propose a rule-ba...
Performance analysis of a power aware routing protocol for ad hoc networks
Yazıcı, Mehmet Akif; Bilgen, Semih; Department of Electrical and Electronics Engineering (2006)
In this thesis, performance of the Contribution Reward Routing Protocol with Shapley Value (CAP-SV), a power-aware routing protocol for ad hoc networking is analyzed. Literature study on ad hoc network routing and ower-awareness is given. The overhead induced by the extra packets of the redirection mechanism of CAP-SV is formulized and the factors affecting this overhead are discussed. Then, the power consumption of CAP-SV is analytically analized using a linear power consumption model. It is shown that CAP...
Performance evaluation of routing protocols in wireless ad hoc networks with service differentiation
Yılmaz, Semra; Koçyiğit, Altan; Erten, Murat; Department of Information Systems (2003)
An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any fixed network infrastructure or centralized administration. Due to the limitations in the wireless environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination. In order to enable communication within the network, a routing protocol is needed to discover routes between nodes. The primary goal of ad hoc network routing pro...
Soft decoding of convolutional product codes on an FPGA platform
Sanlı, Mustafa; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2005)
In today̕s world, high speed and accurate data transmission and storage is necessary in many fields of technology. The noise in the transmission channels and read-write errors occurring in the data storage devices cause data loss or slower data transmission. To solve these problems, the error rate of the received information must be minimized. Error correcting codes are used for detecting and correcting the errors. Turbo coding is an efficient error correction method which is commonly used in various commun...
Action recognition through action generation
Akgün, Barış; Şahin, Erol; Department of Computer Engineering (2010)
This thesis investigates how a robot can use action generation mechanisms to recognize the action of an observed actor in an on-line manner i.e., before the completion of the action. Towards this end, Dynamic Movement Primitives (DMP), an action generation method proposed for imitation, are modified to recognize the actions of an actor. Specifically, a human actor performed three different reaching actions to two different objects. Three DMP's, each corresponding to a different reaching action, were trained...
