Variable-resolution information dissemination

2005 Second Annual IEEE Communications Society Conference on Sensor and Ad Hoc Communications and Networks, 2005. IEEE SECON 2005., 2005
We 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

Location control for information dissemination

2015 American Control Conference (ACC), 2015
The 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, 2011
This 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), 2012
The 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.

The SIFT information dissemination system

ACM Transactions on Database Systems, 1999
Information dissemination is a powerful mechanism for finding information in wide-area environments. An information dissemination server accepts long-term user queries, collects new documents from information sources, matches the documents against the queries, and continuously updates the users with relevant information.

Distributed selective dissemination of information

Proceedings of 3rd International Conference on Parallel and Distributed Information Systems, 2002
To help users cope with information overload, selective dissemination of information (SDI) will increasingly become an important tool in wide area information systems. In an SDI service, users post their long term queries, called profiles, at some SDI servers and continuously receive new, filtered documents.

Community Based Information Dissemination

2015
Given a social network, we study the problem of finding \(k\) seeds that maximize the dissemination of information. Based on the principle of homophily, communities play an important role since information can be disseminated to communities via the seeds.

INFOrmation Dissemination (INFOD) middleware

Proceedings of the Third ACM International Conference on Distributed Event-Based Systems, 2009
The increasing volume, diversity, and complexity of resources and data continues to raise challenges in the sharing and dissemination of information. Although publish-subscribe systems have improved the ability of users to exchange information, we argue that these systems have been either restrictive or simplistic - relying significantly on narrowly ...

Information Dissemination in Mobile CDNs

2008
With the recent development of technologies in wireless access and mobile devices, the mobile network has become a key component of today’s Internet vision [1, 46]. Current mobile networks, which are being deployed worldwide, enable mobility features to new applications and also extend existing wired Web applications to mobile terminals.

Concurrent Broadcast for Information Dissemination

IEEE Transactions on Software Engineering, 1985
Concurrent broadcast involves the dissemination of a database, consisting of messages initially distributed among the nodes of a network, so that a copy of the entire database eventually resides at each node. One application is the dissemination of network status information for adaptive routing in a communications network. This paper examines the time
