Mobil internet protokolü versiyon 4'de yönlendirme optimizasyonlu ve optimizasyonsuz performans analizi

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
