Efficient Schemes for Parallel Communication

Journal of the ACM, 1982
A family of balanced communication schemes for connecting N processors with only a constant number of lines entering or leaving each processor is defined. It is proved that this network topology enables a fully distributed probabilistic algorithm to execute a variety of communication requests efficiently.

Efficient Communication Schemes

1998
We give a survey of recent theoretical results for communication problems in point to point networks. This survey is based on the previous surveys in [57,25]. Communication problems are studied as routing path systems satisfying given communication patterns in a network.

Effective and Efficient On-Line Communication

2012 23rd International Workshop on Database and Expert Systems Applications, 2012
As Web, Web2.0 and semantic channels are constantly growing we are facing new challenge in on-line communication. This paper present a new methodology based on distinguishing and explicitly interweaving content and communication as a central means for achieving content reusability, and thereby scalability over various heterogeneous channels.

Spectrally efficient noncoherent communication

IEEE Transactions on Information Theory, 2002
Summary: This paper considers noncoherent communication over a frequency-nonselective channel in which the time-varying channel gain is unknown a priori, but is approximately constant over a coherence interval. Unless the coherence interval is large, coherent communication, which requires explicit channel estimation and tracking prior to detection ...

Efficiency metrics for wireless communications

2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013
Green wireless communications have received increasing attention from government, academia, and industry. However, how to define a green wireless communication system has been an open topic. In this paper, firstly, we present the definition of green efficiency of wireless links and carry out a comprehensive analysis of the efficiency metrics, e.g., the

An efficient algorithm for group communication

Proceedings of 1993 5th IEEE Symposium on Parallel and Distributed Processing, 2002
We present an algorithm for reliable group communication that guarantees atomicity and total ordering in message delivery. The algorithm has been designed to operate with general omission failures on top of any datagram subnetwork. It allows one to operate within large groups of processes without loss of efficiency and is suitable for an easy ...

Communication efficient parallel searching

1997
Searching is one of the most important algorithmic problems, used as a subroutine in many applications. Accordingly, designing search algorithms is in the center of research on data structures since decades. In this paper we aim to survey recent developments in designing parallel search algorithms where parallel machines are used to answer many search ...

Efficient identification of Web communities

Proceedings of the sixth ACM SIGKDD international conference on Knowledge discovery and data mining, 2000
We de ne a communit y on the web as a set of sites that have more links (in either direction) to members of the community than to non-members. Members of such a community can be eAEciently iden ti ed in a maximum ow / minim um cut framework, where the source is composed of known members, and the sink consists of well-kno wn non-members.

Efficient support for multiparty communication

1994
Communication of multimedia data among multiple parties can be costly in terms of use of network resources if guaranteed quality of service is requested. We believe, however, that knowledge of the functional characteristics of real applications can be helpful to devise new mechanisms to support isochronous communication efficiently.
