Cognitive networks
- IN PROC. OF IEEE DYSPAN 2005
, 2005
"... This paper presents a definition and framework for a novel type of adaptive data network: the cognitive network. In a cognitive network, the collection of elements that make up the network observes network conditions and then, using prior knowledge gained from previous interactions with the network ..."

Cooperative diversity in wireless networks: efficient protocols and outage behavior
- IEEE TRANS. INFORM. THEORY
, 2004
"... We develop and analyze low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals’ relaying signals for one another. We outline several strategies ..."

Modeling and simulation of genetic regulatory systems: A literature review
- JOURNAL OF COMPUTATIONAL BIOLOGY
, 2002
"... In order to understand the functioning of organisms on the molecular level, we need to know which genes are expressed, when and where in the organism, and to which extent. The regulation of gene expression is achieved through genetic regulatory systems structured by networks of interactions between ..."

DNA, RNA, proteins, and small molecules. As most genetic regulatory networks of interest involve many components connected through interlocking positive and negative feedback loops, an intuitive understanding of their dynamics is hard to obtain. As a consequence, formal methods and computer tools
Optimization Flow Control, I: Basic Algorithm and Convergence
- IEEE/ACM TRANSACTIONS ON NETWORKING
, 1999
"... We propose an optimization approach to flow control where the objective is to maximize the aggregate source utility over their transmission rates. We view network links and sources as processors of a distributed computation system to solve the dual problem using gradient projection algorithm. In thi ..."

. In this system sources select transmission rates that maximize their own benefits, utility minus bandwidth cost, and network links adjust bandwidth prices to coordinate the sources' decisions. We allow feedback delays to be different, substantial and time-varying, and links and sources to update
Opportunistic Beamforming Using Dumb Antennas
- IEEE Transactions on Information Theory
, 2002
"... Multiuser diversity is a form of diversity inherent in a wireless network, provided by independent time-varying channels across the different users. The diversity benefit is exploited by tracking the channel fluctuations of the users and scheduling transmissions to users when their instantaneous cha ..."

Random Early Detection Gateways for Congestion Avoidance.
- IEEELACM Transactions on Networking,
, 1993
"... Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving at the gatewa ..."

mechanisms that keep throughput high but avemge queue sizes low. In the absence of explicit feedback from the gateway, there are a number of mechanisms that have been proposed for transport-layer protocols to maintain high throughput and low delay in the network. Some of these proposed mechanisms
A binary feedback scheme for congestion avoidance in computer networks
- ACM TRANSACTIONS ON COMPUTER SYSTEMS
, 1990
"... We propose a scheme for congestion avoidance in networks using a connectionless protocol at the network layer. The scheme uses feedback from the network to the users of the network. The interesting challenge for the scheme is to use a minimal amount of feedback (one bit in each packet) from the netw ..."

Permissible Throughput Network Feedback for Adaptive Multimedia in AODV MANETs
- In Proc. Intl. Conf. on Communications (ICC
, 2001
"... Abstract-- Higher layer protocols in wireless networks need to dynamically adapt to observed network response. A common approach is for each protocol to employ an end-to-end monitoring and measuring mechanism and estimate quantities of interest, usually related to delay, latency or bandwidth. A less ..."

less conventional approach is to employ network layer feedback mechanisms in place or in aid of end-to-end efforts. In this paper we use an 802.11-based link throughput and permissible throughput measurement. In our experiments these source-destination pair permissible throughput measurement
Scalable Feedback Control for Multicast Video Distribution in the Internet

"... We describe a mechanism for scalable control of multicast continuous media streams. The mechanism uses a novel probing mechanism to solicit feedback information in a scalable manner and to estimate the number of receivers. In addition, it separates the congestion signal from the congestion control a ..."
