Parallel Information Dissemination by Packets
SIAM Journal on Computing, 1994Summary: Each vertex of an undirected graph possesses a piece of information that must be sent to every other vertex. They communicate by sending bounded size packets of messages from one vertex to another. The authors describe parallel algorithms, which accomplish the desired tasks for six prominent architectures. The algorithms are optimal, or nearly

The dynamics of quantum information and entanglement is closely linked to the physics of thermalization. A quantum simulator comprised of superconducting qubits has measured the spread of quantum information in a many-body system.

Dissemination of Information on Hypertension
JAMA: The Journal of the American Medical Association, 1982To the Editor.— Jeoffrey K. Stross, MD, and William R. Harlan, MD, stated that they assessed knowledge of the findings of the Hypertension Detection and Follow-up Program (HDFP) in family physicians and internists at two months and six months, respectively (1981;246:360).

The Dissemination of Information
Physics Bulletin, 1965I was interested to see in Dr Gething's letter, on the problems scientists face in acquiring the information they need, his criticism of the poor standard of reproduction of many reports, particularly mathematical work produced by the traditional typewriter and stencil.

Directed information dissemination in VANET
Proceedings of the 7th Asian Internet Engineering Conference, 2011We assume that there exists an inter vehicular network using OLSR where accident information can be propagated to all nodes using on-going OLSR control packets. In order to ensure relevancy of the information, we want to be able to control the direction to which the information should or should not be sent.

Variable-resolution information dissemination
2005 Second Annual IEEE Communications Society Conference on Sensor and Ad Hoc Communications and Networks, 2005. IEEE SECON 2005., 2005We consider the problem of information dissemination in wireless ad-hoc networks. Capacity constraints and the varying needs of applications lead to the need for delivering data at varying resolutions as a function of distance. We introduce a primitive, which we call visibility, to quantify the variable-resolution requirement. We design and analyze new

Sequential information dissemination by packets
Networks, 1992AbstractConsider a network consisting of units and links that connect pairs of units. Suppose each of the units possesses a unique message that is to be received by all other units. This is called gossiping. A related problem is that of census taking in which a particular unit has to receive every other unit's message.

Location control for information dissemination
2015 American Control Conference (ACC), 2015The paper investigates location control for information dissemination, building on our previous work [1] on coverage with information aggregation. In this scenario, information generated in the area needs to be communicated to multiple destinations. The area is partitioned into subregions within which only one node provides service.

Information dissemination on multiple channels
Proceedings of the 30th annual ACM SIGACT-SIGOPS symposium on Principles of distributed computing, 2011This article presents an algorithm for detecting and disseminating information in a single-hop multi-channel wireless network: k arbitrary nodes have information they want to share with the entire network. Neither the nodes that have information nor the number k of these nodes are known initially. This communication primitive lies between the two other

Information dissemination in MIMO networks
2012 IEEE Global Communications Conference (GLOBECOM), 2012The physical-layer multicast transmission that seeks to deliver the common information messages to the all users simultaneously is becoming more important in wireless systems with demand for various multimedia mobile applications such as Multimedia Broadcast Multicast Services.
