Keynote title:
Combining Simulations, Models and Testbeds: Possibilities and Pitfalls

Keynote
abstract:
Recently, the development in the area of decentralized systems and
infrastructureless networks opened avenues for novel applications. A
prominent example is the support of on-site units in large scale
emergency response scenarios. Here, a combination of peer-to-peer
systems and mobile ad hoc networks forms a communication substrate for
offering enhanced services beyond the borderlines of the 'traditional'
infrastructure-based client/server world. More representatives of the
decentralized/infrastructureless domain such as service oriented
architectures and mesh and sensor networks also already left their
starting blocks.
Along with these new technologies new questions regarding their
operational bounds in terms of scalability, security, and QoS arose, to
name just a few. Due to the yet sparse presence of real-world
decentralized and infrastructureless systems, new protocols and
applications have to be scrutinized by means of simulation and in
(small-scale) testbeds. In addition, mathematical models must be
developed both to verify the validity of results obtained from
simulation and testbed studies and to provide tools for the online
adaptation of relevant system parameters in future real-world scenarios.
In this talk we highlight upcoming trends in decentralized systems and
infrastructureless networks. We present recently finished and ongoing
work of German research projects such as SicAri, SoKNOS, and G-Lab that
focus (amongst other objectives) on the emergency response application
scenario. In this context, we identify open issues still demanding for
appropriate models in order to support studies in testbeds and
simulation environments and to help paving the way for real-world
deployment of the developed prototypes.

Bio:
Since early 1996, Dr. Ralf Steinmetz has been a professor at the dept.
of Electrical Engineering and Information Technology as well as at the
dept. Computer Science of the Darmstadt University of Technology,
Germany. There he is in charge of a chair position as managing director
of the "Multimedia Communications Lab". From late 1996 until late 2001
he directed the Fraunhofer (former GMD) Integrated Publications and
Information Institute IPSI. In 1999 he founded the Hessian Telemedia
Technology Competence Center (httc e.V.). On whose board he has since
served as chair. From 2002 to 2004 as dean he managed the department.
His research interests cover networked multimedia issues with the
vision of "seamless multimedia communications"; i.e. network
dependability and security (e.g. gateways, firewalls), quality of
service (e.g. network engineering), content distribution networks (e.g.
streaming), context aware communications (e.g. peer-to-peer
mechanisms), media semantics (e.g. ontology enrichment, metadata). At
Darmstadt he relates these research issues often very closely to
mobility, Internet telephony and telemedia learning.
He has been the editor and co-author of a multimedia course, which
reflects the major issues of the first (updated in several versions)
in-depth technical book on multimedia technology. He has worked as an
editor of various IEEE, ACM and other journals. He has served as chair,
vice-chair and member of numerous program and steering committees of
communications and multimedia workshops and conferences. He is a member
of the GI and VDE-ITG. He was awarded as ICCC Governor, the honour of
Fellow of both, the IEEE and the ACM. In 2005 he became member of the
technology advisory board of the "Hessen Agentur" and he was appointed
as the advisor for information und communications technology by the
Hessian government. Professor Dr. Ralf Steinmetz is a member of the
Scientific Council and president of the Board of Trustees of the
international research institute IMDEA
Networks.

Keynote title:
Resource Management in Broadband Wireless Access Networks
Prof. Dr.
Hossam Hassanein
Telecommunications Research Lab, Queen's University, Ontario, Canada

Keynote
abstract:
the success of emerging Broadband Wireless Access Networks (BWANs) such
as 4G wireless cellular networks championed by Long Term Evolution
(LTE) and IEEE 802.16 broadband wireless networks (WiMAX) will depend,
among other factors, on their ability to manage their shared wireless
resources in the most efficient way. This is a complex task due to the
heterogeneous nature of access networks and the diverse bandwidth and
Quality of Service (QoS) requirements of the applications that these
networks are required support.
Resource Management (RM) in BWANs requires considerations of elements
at different networking dimensions and time scales. This talk describes
our efforts in addressing the challenges to RM in BWANs in three main
directions. The first describes a comprehensive bandwidth provisioning
framework for BWANs at different time scales. We address the problem of
dynamic bandwidth allocation in BWANs. We then discuss packet
scheduling schemes at the frame level that employ practical economic
models through the use of novel utility and opportunity cost functions
to simultaneously satisfy the diverse QoS requirements of mobile users
and maximize the revenues of network operators. The second direction
entails the introduction of novel and non-traditional RM mechanisms
that exploit network heterogeneity. We show how technologies within a
BWAN can be enhanced through joint functionalities. The third direction
shows how vertical handoffs, despite their challenges, can be used to
the benefit of the service provider; and how the use of wireless
multi-hop communication can be utilized in a structurally-hybrid
environment to maintain a robust network operation.

Keynote title:
NOTICE - An Architecture for Traffic Incident Detection
Prof. Stephan
Olariu
Old Dominion University, Norfolk, Virginia, USA

Keynote
abstract:
Road and traffic safety can be improved if the drivers have theability
to
see further down the road and can be informed of relevant traffic
events,
including
collisions and slow-downs. The recently proposed VANETs (Vehicular Ad
hoc
Networks)
are expected to enable both vehicle-to-vehicle (V2V) and
vehicle-to-roadside (V2R)
communications. Virtually all the papers published in the literature
assume that V2V
communications will rely on a strong roadside infrastructure.
Unfortunately, the
roadside infrastructure, is very likely to be the target of theft,
vandalism and
other similar activities that will jeopardize their intended
functionality. Worse
yet, one can easily contemplate a scenario where the roadside
infrastructure may be
hacked and injected with malicious code, rendering it not only useless
but,
downright dangerous.
However, all the VANET systems proposed thus far are afflicted with
serious security
and privacy problems.
Indeed, the way current systems are set up, the driver of a car that
participates in
the traffic will not be able to preserve their privacy and may be
subject to
impersonation or Sybil attacks. The problem stems from the fact that
V2V
communication can be traced back to an individual car. Even if several
pseudonyms
are used, detecting the true identity of the driver and, therefore,
invading their
privacy appears to be unavoidable.
In a sharp departure from the common wisdom we propose to look at
vehicle-to-vehicle
(V2V) and vehicle-to-roadside
(V2R) communications from a different perspective. Instead of relying
on the
roadside infrastructure that is vulnerable to attacks, we propose to
embed
in the
asphalt covering the surface of the roads sensor belts.
Each belt consists of a collection of pressure sensors, optionally
equipped with
piezo-electric elements.
The belts can detect and interact with passing cars.
In this keynote address we discuss in detail NOTICE and show that it
can
be easily
extended to cover many problems of interest in infotainment and
peer-to-peer content
delivery. One important application of NOTICE is with planned
evaluations
when
optimal use must be made of available transportation resource
