IMPACT OF NETWORK STATE INFORMATION ON QoS

by Jana Uramová
"... Delay is one of the crucial factors which influence QoS. This factor depends not only on the network throughput. In case of single channel networks, delay depends on the access mechanism as well. This article reflects single channel network with random access and how the volume of network state info ..."

Network information flow

by Rudolf Ahlswede, Ning Cai, Shuo-Yen Robert Li, Raymond W. Yeung - IEEE TRANS. INFORM. THEORY , 2000
"... We introduce a new class of problems called network information flow which is inspired by computer network applications. Consider a point-to-point communication network on which a number of information sources are to be mulitcast to certain sets of destinations. We assume that the information source ..."

Interference channel with binary fading: Effect of delayed network state information

by Alireza Vahid, Mohammad Ali Maddah-ali, A. Salman Avestimehr - in Proceedings of Allerton Conference , 2011
"... Abstract—We investigate the fundamental limits of communi-cation over binary interference channels with finite states and with delayed network state information at the transmitters. Our results include a novel achievability strategy that systematically utilizes the stale network state information av ..."

Adaptive Protocols for Information Dissemination in Wireless Sensor Networks

by Wendi Rabiner Heinzelman, Joanna Kulik, Hari Balakrishnan , 1999
"... In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation) , that eciently disseminates information among sensors in an energy-constrained wireless sensor network. Nodes running a SPIN communication protocol name their data using high-lev ..."

Information flow and cooperative control of vehicle formations.

by J Alexander Fax , Richard M Murray - In Proceeings of 15th IFAC Conference, , 2002
"... Abstract We consider the problem of cooperation among a collection of vehicles performing a shared task using intervehicle communication to coordinate their actions. We apply tools from graph theory to relate the topology of the communication network to formation stability. We prove a Nyquist crite ..."

to be used for cooperative motion. We prove a separation principle that states that formation stability is achieved if the information flow is stable for the given graph and if the local controller stabilizes the vehicle. The information flow can be rendered highly robust to changes in the graph, thus

GPSR: Greedy perimeter stateless routing for wireless networks

by Brad Karp, H. T. Kung - MOBICOM , 2000
"... We present Greedy Perimeter Stateless Routing (GPSR), a novel routing protocol for wireless datagram networks that uses the positions of touters and a packer's destination to make packet forwarding decisions. GPSR makes greedy forwarding decisions using only information about a router's i ..."

On Throughput Optimality with Delayed Network-State Information

by Lei Ying, Sanjay Shakkottai , 2008
"... We study the problem of routing/scheduling in a wireless network with partial/delayed Network (channel and queue) State Information (NSI). We consider two cases: (i) centralized routing/scheduling, where a central controller obtains heterogeneous delayed information from each of the nodes (thus, the ..."

Cognitive networks

by Ryan W. Thomas, Luiz A. DaSilva, Allen B. MacKenzie - 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 ..."

with the network, plans, decides and acts on this information. Cognitive networks are different from other “intelligent ” communication technologies because these actions are taken with respect to the end-to-end goals of a data flow. In addition to the cognitive aspects of the network, a specification language

Architectural Styles and the Design of Network-based Software Architectures

by Roy Thomas Fielding , 2000
"... The World Wide Web has succeeded in large part because its software architecture has been designed to meet the needs of an Internet-scale distributed hypermedia system. The Web has been iteratively developed over the past ten years through a series of modifications to the standards that define its ..."

Bro: A System for Detecting Network Intruders in Real-Time

by Vern Paxson , 1999
"... We describe Bro, a stand-alone system for detecting network intruders in real-time by passively monitoring a network link over which the intruder's traffic transits. We give an overview of the system's design, which emphasizes highspeed (FDDI-rate) monitoring, real-time notification, clear ..."
