ABSTRACT Performance Analysis of Mobile IPv4 With and Without Route Optimization Altay, Serap Ms, Department of Computer Engineering Supervisor: Asst. Prof. Gülsün Töreci May 2003, 92 pages The support of mobility in the modern communications network is becoming essential and important with the development of mobile devices. Mobile Internet Protocol is built on IPv4. Mobile IP has been proposed by IETF (Internet Engineering Task Force) to support portable IP addresses on Internet. In the basic Mobile IP protocol, datagrams destined for the mobile node are sent from wired or wireless hosts. These datagrams have to travel through the home agent when mobile node is away from home. On the other hand, the datagrams sent from mobile hosts to wired host can be sent directly. This asymmetric routing, called "Triangle Routing". On the other hand, when the destination node is very close to mobile host, this creates a problem. Solving of the problem "Triangle Routing" is one appealing topic in mobile IP. IETF proposed extension part of the basic mobile IP, called "Route Optimization" to address this problem. IPv4 has already been widely deployed. Moreover, it will most probably dominate the Internet for a long time. Therefore, in this thesis implemented mobile IPv4 with and without route optimization in OMNeT++. Simulations have already been done to justify the modification. Keywords: Mobile IP, mobile communication, route optimization, triangle routing. iii
Adi diferensiyel denklemlerin nümerik çözümleri
Since ordinary differential equations are useful in modelling the behavior of many physical processes, methods of solution for these equations are of great importance to engineers and scientists. Even though well-known ana lytical techniques can solve many important differential equations, a greater number of physically significant differential equations can not be solved using these techniques. Fortunately, the solutions of these equations can usually be generated numerically. There are many methods for finding approximate solutions to differential equations. Throughout the thesis, numerical techniques for ordinary differen tial equations are considered. In the first chapter, basic concepts which are going to be used are given. Second chapter contains numerical methods, all of which do not generate exact solutions, only approximate ones. Finally, in the last chapter a new numerical integration technique inspired by the Runge- Kutta method to solve the initial value problem is given. The method pre sented adds higher order derivative terms to the Runge-Kutta stage equations resulting in a higher order method without increasing the number of stages. Keywords: Ordinary Differential Equations, Numerical Analysis, Runge-Kutta Method. IV
Pride and prejudice: Evlilik için rehber
HI ABSTRACT Although criticized for her indifference to the Industrial Revolution or Napoleonic Wars, Austen was a keen observer of her society in terms of relations between man and woman. She reflected her observations in her novels by describing pre-marriage and marriage interaction, as she was aware that in any society matrimony was an institution that best revealed the characteristics of the broad social structure. Austen questioned the marriage types she witnessed: She saw that marriages were either for money or for sex. Thus, neither man nor woman was happy. For Austen, simple love, too, was not a reliable ground on which marriage could be based. To reveal her successful matrimony concept, Austen compares different marriage types in Pride and Prejudice. In her opinion, readers would be able to find the "ideal marriage type" by reading in between the lines. For Austen, the ideal marriage is an agreement between social demands and personal desires, and this makes the union fulfilling andIV respectable. Yet, this respectability does not mean "noble" family title, wealth, or "influential" acquaintances. At this point, by stressing the importance of individuality, Austen challenges the bourgeois viewpoint, which gives priority only to social rank and money. She is aware that equalizing the public and private forces is a difficult task. However, she shows the readers that individuals like Elizabeth and Darcy are able to go through this laborious formation and find happiness in marriage.
Transformation of perspective of man and the universe from Alfred, Lord Tennyson to Thomas Hardy
ABSTRACT The conflict between religion and science started after the Renaissance in the west and continued through the age of Copernicus and Galileo to the 19th century. During this conflict, many people especially the scientists, tried to enlighten people's minds at the cost of paying high prices. Copernicus and Galileo were among those scientists who suffered a lot from this conflict and even were accused of being against the doctrines of the Christian Church. The conflict between religion and science reached its climax during the Victorian Age, which was both called the age of scientific advancements and the age of religious controversies. Scientific findings, which conflicted with the teachings of the Bible caused a definite crisis of faith and the people of the age began questioning the meaning of life and the existence of God. Alfred, Lord Tennyson was one of these people who found himself in a profound doubt and came at the verge of loosing his former belief after reading Lyell's Principles of Geology and Chambers' Vestiges of Creation. Under the influence of scientific views of his time, Tennyson wrote his famous poem In Memoriam A.H.H which reflected all his doubts, conflicts and finally his consolation by reconciling science and faith. mIn the following decades it was Thomas Hardy who continued Tennyson's uncertainties. Although he was a devoted Christian in the first part of his life, after the publication of The Origin of Species he started to loose his former religious values. Influenced by the ideas of Darwin and Huxley, he called himself a "harmless agnostic" and became more and more cynical about the existence of God. As poets who were highly aware of the scientific advancements of their time, Tennyson and Hardy reflected these ideas through their poems. IV
Religion and women in George Eliot`s Adam Bede
m ABSTRACT Since her childhood George Eliot was a keen observer of her time in terms of human relationships, woman's status in society, and the concept of religion. Eliot reflected her observations in her novels by stating her views on the place and importance of religion in human life, and by discussing the social problems of her time. She lived in Victorian society, which was characterised by limited mobility or very little flexibility in terms of social behaviour and rules particularly for women. That is to say, the norms of the Victorian Age might be interpreted as a difficult life for most of its people. As an incongruous individual of her time, George Eliot did not sacrifice her own ideals, her sense of religion, and social behaviour. She was radically different from the characters she depicted in her fiction; she did not reflect a traditional ladylike figure of her time inIV her real life. Her novels provided her with ample opportunity and great freedom to reflect herself freely because fiction was her domain where there were no obstructions, limitations, and rules. Eliot never tried to impose her own way of living to her readers in her novels. For instance, her novel, Adam Bede, includes strong religious faith and moral teaching which does not fall in line with her real life. Rather, through the protagonists she emphasizes over and over again the significance of religion and praises the value of religious doctrines. Eliot deals with the concept of religion in Adam Bede through several contradictory characters to show that religion provides lessons and enables man to find his way in his life journey. The novel also emphasizes that religion offers comfort in times of trouble and provides hope in the midst of despair. In brief, religion in the novel suggests that the world is not only permeated with trouble and confusion, it is at the same time a friendly home created for man by the Divine Essence.
