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.

Abstract
Ambient Networks (AN), is a new
networking concept for beyond 3G fixed and wireless
networks. It has its origin in the well known concepts of
ambient intelligence and user-centric systems, where the
network autonomously adapts to the user’s intentions. It was
developed in the context of an IST-project funded under the
European Union’s Sixth Framework Program (FP6). One of its
key features is the autonomic cooperation between
heterogeneous networks. This cooperation, termed network
composition, happens at the control layer and between
different networks. It is quite different from the more
widely-known concept of cooperative communications and
networking where nodes of a same network cooperate. It is
intended to overcome the shortcomings of today’s static
network cooperation (e.g. roaming in cellular networks),
which requires off-line agreement negotiation and extensive
manual configuration. The need for these off-line agreements
actually allows access to only a limited range of services
and makes cooperation time-consuming and sometimes
impossible. In this speech, we discuss briefly roaming in 3G
cellular networks and pinpoint the shortcomings. This is
followed by an introduction to the basics of ambient
networking as envisioned by the EU 6 FP project. The
principles, protocols and algorithms of ambient network
composition are then discussed and illustrated by case
studies. Research directions are identified throughout the
speech.

Industrial Presentation
Towards user generated applications on the
Internet-of-Things (IoT): Ambient Assistive Living and DiY
applications as first proof points

Abstract
The Ambient Media department in Bell Labs
(Alcatel-Lucent) is a multidisciplinary team that
investigates application trends towards Ambient
Intelligence, Assisted Living, Locative Media and Smart
Cities that are expected to change the technology and
eco-system settings drastically. Our main focus is to enable
mass creativity of Internet of things applications by non
skilled users in order to achieve an increased value or
participation for users, cities or society.
In this talk we will report some first proof points for
user generated applications for the Internet-of-Things,
highlighting the multidisciplinary.
In the first part of the talk, we will introduce the
notion of Internet-of-Thing, and answer some research
challenges on what the Internet-of-Things could bring to the
user, what are the missing pieces, how user-thing
interactions need to be enhanced, and how the
user-environment interaction would need to be rethought.
In the second part, we will show how this vision is
feasible and illustrate a proof point in an ambient
assistive living environment where non-technically skilled
people can create & control their own ambient applications:
Casensa. Casensa is a context-aware system that can be
installed in houses of elderly to support them in everyday
life activities. In a tangible way they can define their own
smart home by creating the supportive smart behavior of the
house and have control over the activation and deactivation
of the smart home behavior. Casensa is an adaptive system:
when the needs of a person change and s/he needs a new or
other support of the system, s/he can in a simple way define
new smart supportive behavior. We will illustrate Casensa by
a video.
