Titre | Convergence in B3G/4G Networks - An Enabler of Ubiquitous Computing |
Résumé | Beyond 3G (B3G) or 4th Generation (4G) wireless networks are no
more a dream, already knocking at the doors of our information
village. 4G promises to offer a vast range and diversity of
converged devices, services and networks in order to
revolutionize the way we communicate today. 4G would not only
offer ultra-high data rates but would also enable ubiquitous
computing paradigm, particularly interesting for the
end-user with the help of various personalized and user-
friendly services. B3G/4G networks will be composed of
heterogeneous elements at different technological levels
ranging from services to user-terminal. This multi-dimensional
heterogeneity obstructs the B3G/4G networks to be largely
deployed and become economically and socially viable.
Convergence is a key to offer a unified solution where all
these highly heterogeneous components are coupled together to
give a homogeneous outlook. While the research community is
interested in unification and Interworking of B3G/4G
heterogeneous elements at various scales such as converged
services and devices, core and access network convergence,
Fixed-Mobile Convergence (FMC) and so on; our particular focus
in this talk is on Wireless Network Convergence and
Multiple-Interface Terminal Convergence aspects of B3G/4G
systems. At the first place, we discuss how the wireless
network convergence in B3G/4G preserves the benefits of
conventional infrastructure-based networks while incorporating
the flexibility of mobile ad-hoc networks by introducing the
novel converged architectures such as Wireless Mesh Network
(WMN), Multi-hop Cellular Networks (MCN) and Hybrid Wireless
Networks (HWNs). Furthermore, we bring to light the
proliferation of multi-interface, multi-mode and multi-
functional user-terminals that are capable to connect with a
plurality of access networks/devices at short/long distance at
the same time. This proliferation introduces the stringent
requirements of Interworking and convergence at the terminal-
level in order to provide efficient mobility management in
heterogeneous B3G/4G networks. Finally, we conclude our talk by
giving our personal stance on the importance of convergence,
which is the only widely agreed-upon solution to make the inte-
gration of 4G elements go unnoticed to the end-user's environ-
ment, so that the technology eventually focuses over the user
and not the user focuses on the diversity and immensely
heterogeneous elements of the technology.
