Call For Papers
Challenged networks are characterized by a heterogeneous mix of nodes and widely varying network conditions. Nodes in today's challenged networks often include mobile nodes, space-based nodes, sensor/actuator nodes and other devices. Performance of the network paths interconnecting such nodes can be highly varying in terms of bandwidth, latency, disruption characteristics and security requirements. Conventional Internet access in performance-limited environments such as developing countries can also be regarded as challenged networks as can be ad-hoc communication between personal devices.
The Internet protocol architecture suffers some problems when used in a challenged network setting. For example, when disconnection and reconnection is common or link performance is highly variable or extreme, one or more of the traditional Internet protocols do not work well. In this workshop following CHANTS 2007, CHANTS 2006 and WDTN 2005, we wish to explore ongoing efforts in dealing with physical networks that operate significantly differently from wired, connected networks and the protocol architectures and algorithms used to deal with such situations. Techniques for making applications tolerant to disruptions and/or high delays are also in scope.
We specifically solicit papers in the following areas:
Characterization of performance-challenged networks e.g. network measurements
Networking systems operating over unusual/challenged networks
Protocol design and evaluation of operations over challenged networks
System architecture and design for challenged networks
Applications in challenged networks
Robust network application design and implementation techniques
Delay tolerant and disruption tolerant networks (DTN)
Configuration and management of challenged networks
Submissions may include presentations of specific systems or
performance measurements, as well as architectural papers
addressing new concerns. Papers that bring out problems in the
existing proposals for challenged networks or that report
operational experience will be favored. Selected papers will
be forward-looking, will describe their relationship to
existing work, and will have impact and implications for
ongoing or future research. We aim to accept approximately 12
papers, and to have a highly interactive workshop focusing on
evolving this area of network research and continuing to build
In addition, we seek submission of demo proposals, also to be
reviewed by the TPC. The demo proposals shall present recent
practical results from the area of challenged networks. In
exceptional cases, where live demos are simply not practical
to present, poster or video presentations of practical results
are acceptable, too.
Paper Format and Submission
Submitted papers must be no more than 8 pages long, two
columns, with no characters in smaller than 10 point fonts,
and must fit properly on US "Letter"-sized paper (8.5x11
inches). Margins must be of 1 inch on all edges (top, bottom,
left, and right) of each page.
Demo proposal abstracts (to be published as part of the
proceedings) shall not be longer than 3 pages plus 1 page
description of the precise setup and requirements.
All paper submission will be handled via EDAS.
