(2007), pp.
79-79.Traffic
grooming can
be used in
IP-over-WDM
networks to
efficiently
utilize the
bandwidth of
wavelength
channels. In
grooming
networks,
however, the
number of
lightpaths
that need to
be managed is
high and empty
time-slots may
be switched
together with
time-slots
taken by
traffic. These
empty
time-slots add
an induced
connectivity
to the network
and, to use
this induced
bandwidth,
quite complex
induced
topologies
need to be
managed,
increasing the
computation
time. In this
paper we
present an
approach to
efficiently
use the
induced
bandwidth
while
alleviating
the management
of complex
topologies. A
network
operating
dynamically is
used to test
the
effectiveness
of such
approach.NSC

pp.
256-263.The
Rutgers Master
II-ND glove is
a haptic
interface
designed for
dextrous
interactions
with virtual
environments.
The glove
provides force
feedback up to
16 N each to
the thumb,
index, middle,
and ring
fingertips. It
uses custom
pneumatic
actuators
arranged in a
direct-drive
configuration
in the palm.
Unlike
commercial
haptic gloves,
the
direct-drive
actuators make
unnecessary
cables and
pulleys,
resulting in a
more compact
and lighter
structure. The
force-feedback
structure also
serves as
position
measuring
exoskeleton,
by integrating
noncontact
Hall-effect
and infrared
sensors. The
glove is
connected to a
haptic-control
interface that
reads its
sensors and
servos its
actuators. The
interface has
pneumatic
servovalves,
signal
conditioning
electronics,
A/D/A boards,
power supply
and an
imbedded
Pentium PC.
This
distributed
computing
assures much
faster control
bandwidth than
would
otherwise be
possible.
Communication
with the host
PC is done
over an RS232
line.

it is critical
to subject it

these

that the above

that is, the

4.Selfish
overlay
networks
consist of
autonomous
nodes that
develop their
own strategies
by optimizing
towards their
local
objectives and
self-interests
, rather than
following
prescribed
protocols. It
is thus
important to
regulate the
behavior of
selfish nodes,
so that
system-wide
properties are
optimized. In
this paper, we
investigate
the problem of
bandwidth
allocation in
overlay
networks, and
propose to use
a
market-driven
approach to
regulate the
behavior of
selfish nodes
that either
provide or
consume
services. In
such markets,
consumers of
services
select the
best service
providers,
taking into
account both
the
performance
and the price
of the
service. On
the other
hand, service
providers are
encouraged to
strategically
decide their
respective
prices in a
pricing game,
in order to
maximize their
economic
revenues and
minimize
losses in the
long run. In
order to
overcome the
limitations of
previous
models towards
similar
objectives, we
design a
decentralized
algorithm that
uses
reinforcement
learning to
help selfish
nodes to
incrementally
adapt to the
local market,
and to make
optimized
strategic
decisions
based on past
experiences.
We have
simulated our
proposed
algorithm in
randomly
generated
overlay
networks, and
have shown
that the
behavior of
selfish nodes
converges to
their optimal
strategies,
and resource
allocations in
the entire
overlay are
near-optimal,
and
efficiently
adapts to the
dynamics of
overlay
networks.W
