ABSTRACT: Self-organizing networks have recently attracted a lot of
attention in
different disciplines including physics, electrical engineering,
computer science, mathematics, cybernetics, etc. The overarching
phenomenon in most of these different disciplines is the need and
desire to mimic what nature provides in living organisms naturally
(e.g., in the case of human beings, the immune system); i.e., the
ability of a system or network to re-organize (or self-organize)
itself, without outside intervention, after a part in the system is
destroyed or harmed, so that it can continue to perform most of its
previous functionalities in a non-disrupted and smooth manner. In this
talk, we discuss two such emerging application areas that hold great
promise.
In the first part of the talk, we will consider wireless ad hoc and
sensor networks which use the self-organization paradigm for
networking without using the existing telecommunications
infrastructure. This new paradigm will allow communication between
hundreds (perhaps thousands) of nodes when the nodes can not use an
existing infrastructure, thus addressing the increasing demands of
mobility in contemporary and future society. In particular, we will
introduce a new approach for the design and deployment of wireless ad
hoc and sensor networks. This new bottom-up approach is essentially a
communication-theoretic approach and it is in stark contrast to other
approaches pursued in the open literature. We show that this
bottom-up approach (as opposed to the conventional top-down approach
typically pursued in computer networking) is a very promising new
approach that can give fundamental insights into the design and
deployment of future wireless ad hoc and sensor networks.
In the second part of the talk, we consider a related problem; namely,
how to build self- organizing networks from current cellular
networks. It is well-known that that the centralized network
architecture of cellular networks does not allow self-organization.
To circumvent this problem, we propose to deploy cheap and simple
relay stations in cellular networks which can transform them into
self-organizing networks. In particular, we provide a topology
generation algorithm for converting a cellular network into a
self-organizing network and we investigate whether the small-world and
scale-free (also known as the power law) properties are also valid for
this application.
SHORT BIO:
Ozan Tonguz is a full professor in Electrical & Computer Eng. Dept. at
Carnegie Mellon University (CMU). He is a Co-Director of the Center for
Wireless And Broadband Networking Research at CMU. He is the author of a
Wiley bestseller entitled "Ad Hoc Wireless Networks: A
Communication-Theoretic Perspective". He has published about 200 papers in
IEEE journals and conference proceedings. He is well-known for his
contributions in optical networks (optical transmission-access-
networking; especially, radio over fiber networks, coherent lightwave
transmission systems, and amplified direct-detection lightwave
transmission sytems) and wireless communications and networks (physical
layer communications, access, and networking).
