This Project is dedicated to my beloved family and friends, without their staying
power, patience, understanding, for their endless support and encouragement, the
conclusion of this work would not have been possible.

ACKNOWLEDGEMENT
First and foremost, I would like to thanks ALLAH SWT, all praises be to
ALLAH the most merciful and most kind because on his blessings, who has made
me able to successfully complete this project report Thank you for everything.
I
would like to express heartfelt gratitude to my supervisor Dr.Izzeldin Ibrahim for
his constant support during my study at UTM. He inspired me greatly to work in this
project. His willingness to motivate me contributed tremendously to our project. I
have learned a lot from him and I am fortunate to have him as my mentor and
supervisor.
Besides, I would like to thank the authority of Universiti Teknologi Malaysia
(UTM) for providing me with a good environment and facilities such as MIMOS lab
to complete this project with software which I need during process.
My darling family you are greatest blessing in my life. Your support and
understanding gave me the strength to complete my project. Thank you for the
endless love that is still surrounding me and keeping me safe. To all my friends, I
would like to say thank you for helpful advices, devotions and kindness. So accept
my gratefully appreciation for being that valuable for me.
Also I would like to express my heartfelt pleasure to all those who have
directly or indirectly offered help, support and suggestions, contributing toward the
successful completion of this project. Your kind words of comfort and understanding
were deeply appreciated.

ABSTRACT
Next generation 4G wireless networks is envisioned as a convergence of
different wireless access technologies providing the user with the best anywhere,
anytime connection and improving the system resource utilization. However the
study of evaluation mobile communication system, mobility management in
heterogeneous network, mobility management classification, seamless mobility and
handover strategies. In the wireless heterogeneous environment, the majority of
problems in the case of handovers stem from the issue of uncertainty in the
prediction of network coverage and the duration of availability of network services.
The objective of this thesis is to analyze the integration between Universal Mobile
Telecommunication System (UMTS) and Wireless Location Area Network (WLAN)
during handover process. And then evaluate the impact of seamless vertical handover
on the system performance in terms of delay, throughput and packet loss. The
simulation tool to achieve the objectives is OPNET 14.5 Modular; we have designed
two integration scenarios for Open and Loose coupling scheme and then compared
that two integration schemes however result shows that loose coupling architecture is
better than open coupling architecture. The results also shows when the user move
between two different technology networks shows that loose coupling architecture is
better than open coupling architecture in terms of delay, throughput and packet loss.
Furthermore the analytical framework extends to multiple radio network
environments and the possibilities of the use of Experimental enhance handover
operation.

ABSTRAK
Generasi seterusnya bagi 4G rangkaian tanpa wayar adalah digambarkan

kebolehmudahalihan dalam pelbagai rangkaian, pengurusan kebolehmudahalihan
pengelasan, kebolehmudahalihan kelancaran dan strategi penyerahan. Dalam
persekitaran pelbagai rangkaian, masalah yang utama dalam kes penyerahan
berpunca daripada isu ketidakpastian dalam meramal liputan rangkaian dan tempoh
kemudahan rangkaian yang tersedia. Objektif tesis ini adalah untuk menganalisis
kesepaduan antara Sistem Telekomunikasi Mudah Alih Universal (UMTS) dan
Wireless Locatioan Area Network (WLAN) semasa proses penyerahan. Kemudian,
menilai kesan kelancaran penyerahan menegak ke atas prestasi sistem dalam bentuk
penangguhan, hasil dan kehilangan paket. Perkakas simulasi untuk mencapai objektif
adalah OPNET 14.5 Modular; kami telah mereka 2 senario bersepadu untuk skema
gandingan Open dan Loose dan kemudian membandingkan dua skema bersepadu
tersebut. Bagaimanapun keputusan menunjukkan, seni bina gandingan Loose adalah
lebih baik berbanding seni bina gandingan Open Keputusan menunjukkan apabila
pengguna beralih diantara dua rangkaian teknologi yang berbeza, senibina gandingan
Loose adalah lebih baik daripada senibina gandingan Open dari aspek penangguhan,
hasil dan kehilangan paket.Selain itu, rangka kerja analisis boleh dikembangkan
kepada pelbagai persekitaran rangkaian radio dan mempunyai peluang untuk
digunakan bagi Eksperimen mengembangkan operasi penyerahan.
