Analysis Of Umts Handoffs For FTP And Http Applications Based On Simulation In Opnet
نویسندگان
چکیده
This research paper is based on simulation and analysis of QOS parameters for hard and soft handoffs. Performance of UMTS scenario is evaluated for various multimedia applications like FTP and HTTP. To accomplish the task of simulation OPNET TM 14.5 modulator used. From results, soft handoff is better than hard handoff because soft handoff support connections during mobility and handoff.

Performance Evaluation of QoS in WLAN-UMTS Network Using OPNET Modeller
Seamless connectivity is need of next generation wireless network (NGWN). WLAN, WiMAX and UMTS are the main components of wireless network connected in integrated manner. These networks, each with its own characteristics, connected to a common IP-based core network to provide mobile user with seamless connectivity. One of the major issues for the converged heterogeneous networks is to provide s...
متن کاملPerformance Analysis of Various Application Protocols for MANET
A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried without any centralized control. The ease of deployment and the infrastructure less nature of Mobile Ad Hoc Networks (MANET) make them highly desirable for present day multi media communications. In this paper we analyze the performance of TCP/IP based application protocol ...

متن کاملThroughput and Delay Performance of Mobile Internet Applications Using LEO Satellite Access
Low Earth Orbit (LEO) satellites are an essential complement of the cellular radio infrastructure, especially the Universal Mobile Telecommunications System (UMTS), for mobile (pedestrian and, more important, vehicular) access to the Internet in sparsely populated areas, where high bandwidth UMTS cells cannot be economically deployed. LEO users would eventually switch between the satellite segm...
متن کاملConfidentiality in the UMTS Radio Access Network Simulation approach under OPNET
The Universal Mobile Telecommunications System (UMTS) offers a panoply of 3G services. In addition to delivery of images, graphics and video communications, UMTS is used for such applications as banking and e-commerce and hence security is a critical concern. In the present paper, we are interested in the confidentiality feature in the UMTS Network Access. Ciphering when applied is performed in...
