Information dessimnation in Social Nets

The Java applet shows the self-managed information dessimination in social net with monitoring metrics (at the right). This could be a good idea to implement a online-benchmarking application with user input to determine different quality and performance parameters. Since, information are disseminated in self-configured way, it could be used for monitoring resources, services including security, etc. The interesting question could be how the collect or disseminate information for productive activity.

PageRank, LinkRank, ComRank, WikiFactor, PageFactor, ComFact

PageRank: This is an algorithm which ranks a web-page among set of web-page on WWW by considering a large set of different variables.
LinkRank: is a method of quantifying the modularity of social links in directed network. The original paper assumes modularities in un-directed networks and optimizes it for directed networks.
WikiFactor: "A new metric is introduced, inspired by the Hirsch {\it h-index}, to measure the impact of a wiki site. A table of wikiFactors is presented for a number of wikis, in particular those oriented towards scientific topics. The wikiFactor is defined as the number of web pages, wF, that have had $\ge 1000$wF visits."

Referring to these links one reasonable question would be haw to rank communities, services, privacy settings in sub-graphs or along the whole graph. But what one could buy out of this? Well, considering services provisions and service management, one should provide provide load balancing, some what deterministically routing, or have surgically prune out bad guys (cheaters in MMOG, attackers, or selfish guys).

@ LinkRank: One can predict link, LinkPrdict, by predicting previously un-observed relationship and hence behavior. There are many exciting applications of this particular area of network science. Most research in the area of link prediction has been restricted to scoring based on a single measure within network topologies. While the research considers new measure and placing existing measures in the context of a machine learning task. "We are also casting the problem as a high class imbalance task."

IEEE Network magazine - Special Issue on Cloud Computing

http://dl.comsoc.org/livepubs/ni/info/cfp/cfpnetwork711.htm

Background

Cloud Computing is a recent trend in information technology
and scientific computing that moves computing and data away
from desktop and portable PCs into large Data Centers.
Cloud computing is based on a model for enabling convenient,
on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage,
applications, and services) that can be rapidly provisioned
and released with minimal management effort or service
provider interaction. Cloud Computing opens new perspectives
in internetworking technologies, raising new issues in the
architecture, design and implementation of existing networks
and data centers. The relevant research has just recently
gained momentum and the space of potential ideas
and solutions is still far from being widely explored.


Scope

This special issue of the IEEE Network Magazine will feature
articles that discuss networking aspects of cloud computing.
Specifically, it aims at delivering the state-of-the-art
research on current cloud computing networking topics, and
at promoting the networking discipline by bringing to the
attention of the community novel problems that must be
investigated.
Areas of interest include, but are not limited to:

Data center architecture
Server interconnection
Routers (switching technology) for data center deployment
Centralization of network administration/routing
Energy-efficient cloud networking
Low energy routing
Green data centers
Measurement-based network management
Traffic engineering
Network anomaly detection
Usage-based pricing
Security issues in clouds
Secure routing
Security threats and countermeasures
Virtual network security
Virtual Networking
Virtualized network resource management
Virtual cloud storage
Futuristic topics
Interclouds
Cloud computing support for mobile users


Manuscript Submission

Authors should submit their manuscript electronically in PDF
format by email to all the guest editors according to the
timetable. Authors are encouraged to register their papers by
submitting the paper abstract, the paper title, authors and
keywords by the corresponding deadline. Prospective authors
must prepare their original submissions in accordance with
the IEEE Network guidelines to authors,
http://dl.comsoc.org/livepubs/ni/info/authors.html. Articles
should not exceed 4500 words, be tutorial in nature, and
should be written in a style comprehensible to readers
outside the specialty of the article. The title page should
include the paper title, authors and keywords. Figures
and tables should be limited to a combined total of six.
All submissions will be reviewed based on
technical merit and relevance.
