Abstract

Posljednjih godina možemo opaziti da ljudi postaju sve više ovisni o
korištenju osobnih mobilnih uređaja. Pružanje Internet usluga uređajima
krajnjih korisnika uz zadržavanje postojece razine kvalitete usluge
(QoS) postaje neophodno. Korisnici mobilnih uređaja su stalno
u pokretu zbog cega mobilnost predstavlja kljucni faktor u današnjim
komunikacijama. Host-multihoming omogucuje uređajima krajnjih
korisnika koji su opremljeni s više mrežnih sucelja, mogucnost istovremene
povezanosti na više pristupnih mreža. Time je moguce
optimalno iskoristiti resurse koji su u dometu uređaja krajnjih korisnika
i osigurati vecu pouzdanost veze. Primjenjivanjem mobilnosti i
host-hultihominga u bežicnim mrežama, moguce je zadovoljiti sve zahtjevnije
želje korisnika i omoguciti bolju iskoristivost mreže. Kada se
ovi mehanizmi primjene u mreži, važno je prikazati njihove mogucnosti i
funkcionalnosti. Vizualizacija pruža intuitivan i zanimljiv nacin razumijevanja
promjena koje se događaju u mreži. Međutim u svrhu demonstriranja
njihove funkcionalnosti, potrebno je komunicirati s mrežnim
cvorovima i udaljeno pokrenuti mreže akcije. Ove aktivnosti također je
potrebno vizualizirati kako bi se mogle razumjeti promjene koje su se
dogodile u mreži. Cilj ovog diplomskog rada je razviti visualizacijsku
platformu koja omogucava vizualizirati mobilnost i host-multihoming
u mreži. Također platforma treba posjedovati mogucnost komunikacije
s mrežom i udaljenog pokretanja radnji u mreži. U tu svrhu, platforma
je razvijena i integrirana u postojeci mobilni protokol s multihoming
podrškom. Kako bi se provjerila funkcionalnost razvijene platforme,
testbed je bio uporabljen u laboratorijskim uvjetima i ispitivanja su
provedena u svrhu provjere funkcionalnosti i procjene ucinkovitosti. Dobiveni
rezultati jasno pokazuju da je razvijena platforma u mogucnosti
prikazati mobilnost i host-multihoming u mreži u stvarnom vremenu.
Također, platforma može komunicirati s mrežnim cvorovima i pokrenuti
mrežne radnje, ciji rezultati su prikazani i vidljivi u platformi.

Abstract (english)

In the last years we have witnessed that people are becoming increasingly
dependent on the use of personal mobile devices. Providing Internet
access to users’ devices while maintaining Quality-of-service has
become indispensable. The users are constantly moving, and mobility
presents a key factor in today’s communications. Host-multihoming
allows end-user devices equipped with multiple network interfaces to
be simultaneously connected to multiple access networks. This can optimally
leverage the resources that are in the range of the end-user device
and provide a greater sense of connection reliability. Implementing
both mobility and multihoming in wireless networks can accommodate
the increasing demands of the users and provide better user experience
and network utilization. When these mechanisms are implemented in
the network, it is important to present their features and demonstrate
their functionalities. Visualization provides an intuitive and interesting
way of understanding the changes that occur in the network. In order
to demonstrate the functionalities, it is necessary to interact with the
network nodes and remotely trigger network actions. These actions
should also be visualized to understand the changes that happened in
the network. The objective of this Dissertation is to develop a visualization
platform able both to visualize mobility and multihoming in the
network, and interact with the network to remotely trigger network actions.
For this purpose, a framework has been developed and integrated
in a mobility protocol with multihoming support. To demonstrate the
functionalities of the developed platform, a testbed has been deployed
in the laboratory environment and tests were performed to verify the
implemented functionalities and evaluate its performance. The results
show that the platform is able to visualize both mobility and multihoming
in real-time. Also, the platform can interact with the network nodes
in order to trigger network related actions, and visualize the result of
these actions.
