Bluetooth scatternets: an enhanced adaptive scheduling scheme Tập 2 - Trang 782-790 vol.2
S. Baatz, M. Frank, C. Kuhl, P. Martini, C. Scholz
The vision of ad-hoc networking with Bluetooth includes the concept of devices
participating in multiple "piconets" and thereby forming a "scatternet".
However, the details of scatternet support for Bluetooth are not specified yet.
This paper presents a scheme for Bluetooth scatternet operation that adapts to
varying traffic patterns. Being based on sniff mode, it does not require
substantial modi... hiện toàn bộ

Delay constrained energy efficient transmission strategies for wireless devices Tập 3 - Trang 1765-1772 vol.3
P. Nuggehalli, V. Srinivasan, R.R. Rao
In this paper, we address the problem of energy efficient packet scheduling in a
wireless environment. We consider a wireless transmitter which is limited by its
finite battery resource. Our objective is to design a transmission schedule that
maximizes battery lifetime subject to some delay constraints. To achieve this,
we exploit two previously unconnected ideas: (i) channel coding can be used to... hiện toàn bộ

Positive correlations and buffer occupancy: lower bounds via supermodular ordering Tập 3 - Trang 1298-1306 vol.3
S. Vanichpun, A.A. Makowski
We use recent advances from the theory of multivariate stochastic orderings to
formalize the "folk theorem" to the effect that positive correlations lead to
increased buffer occupancy and larger buffer levels at a discrete-time infinite
capacity multiplexer queue. Input sequences are compared in the supermodular
(sm) ordering and buffer contents in the increasing convex (icx) ordering,

How to market-manage a QoS network Tập 1 - Trang 284-293 vol.1 - 2002
J. Altmann, H. Daanen, H. Oliver, A.S.-B. Suarez
This paper describes a control mechanism for a future Internet. It is an
economic mechanism that enables users to choose different pairs of price/QoS
priority levels for network services at the user time scale. The user time scale
means that prices vary at a rate suitable for human beings to respond to those
price changes. The changes might happen on an hourly, daily, or weekly basis. We
believe t... hiện toàn bộ

Predicting Internet network distance with coordinates-based approaches Tập 1 - Trang 170-179 vol.1
T.S.E. Ng, Hui Zhang
We propose using coordinates-based mechanisms in a peer-to-peer architecture to
predict Internet network distance (i.e. round-trip propagation and transmission
delay). We study two mechanisms. The first is a previously proposed scheme,
called the triangulated heuristic, which is based on relative coordinates that
are simply the distances from a host to some special network nodes. We propose
the se... hiện toàn bộ

Size-based adaptive bandwidth allocation: optimizing the average QoS for elastic flows Tập 2 - Trang 657-666 vol.2
Shanchieh Yang, G. de Veciana
With a view on improving user perceived performance on networks supporting
elastic flows, e.g., multimedia/data file transfers, we identify the key
properties that an online dynamic bandwidth allocation policy should have. We
then propose a family of bandwidth allocation criteria which depends on the
residual work of on-going transfers. Analysis and simulations show that
allocating bandwidth in th... hiện toàn bộ

A Poisson limit for buffer overflow probabilities Tập 2 - Trang 994-1003 vol.2
J. Cao, K. Ramanan
A key criterion in the design of high-speed networks is the probability that the
buffer content exceeds a given threshold. We consider n independent identical
traffic sources modelled as point processes, which are fed into a link with
speed proportional to n. Under fairly general assumptions on the input processes
we show that the steady state probability of the buffer content exceeding a
threshol... hiện toàn bộ

Real-time model and convergence time of BGP Tập 2 - Trang 893-901 vol.2
D. Obradovic
BGP allows routers to use general preference policies for route selection. This
paper studies the impact of these policies on convergence time. We first
describe a real-time model of BGP. We then state and prove a general theorem
providing an upper bound on convergence time. Finally, we show how to the use
the theorem to prove convergence and estimate convergence time in three case
studies.

Energy-efficient scheduling of packet transmissions over wireless networks Tập 3 - Trang 1773-1782 vol.3
A. El Gamal, C. Nair, B. Prabhakar, E. Uysal-Biyikoglu, S. Zahedi
The paper develops algorithms for minimizing the energy required to transmit
packets in a wireless environment. It is motivated by the following observation:
In many channel coding schemes it is possible to significantly lower the
transmission energy by transmitting packets over a long period of time. Based on
this observation, we show that for a variety of scenarios the offline
energy-efficient t... hiện toàn bộ
