CHANTS 2009
ACM MobiCom 2009 Workshop on Challenged Networks
--------------------------------------------------------
Beijing, China
September 25, 2009

Scope:
------
Challenged networks are characterized by a heterogeneous mix of
nodes, nodal churn, intermittent connectivity, and widely varying
network conditions. Conventional Internet access in
performance-limited environments such as developing countries with
insufficient infrastructure and severe power shortage can be
regarded as challenged networks, as can be ad-hoc communication
between personal mobile devices; even an overlay network relying on
fixed infrastructure might be challenged by a high degree of churn.
Challenges are also posed by a very heterogeneous and potentially
resource limited nodes, such as mobile phones, space-based nodes,
and sensor and actuator nodes. Performance of the network paths
interconnecting such nodes can be highly unreliable and varying in
terms of bandwidth, latency, disruption characteristics and security
requirements.
The Internet protocol architecture suffers when used in a challenged
network setting. For example, when connectivity is intermittent, or
the link performance is highly variable or extreme, then one or more
of the traditional Internet protocols do not work well. In this
workshop following CHANTS 2008, CHANTS 2007, CHANTS 2006 and WDTN
2005, we wish to explore ongoing efforts in dealing with networks
that operate under significant challenges as exemplified above;
techniques for making applications tolerant to disruptions, churn
and high delays are also of interest.
The focus of this year's workshop will be on experiences with
challenged networks, such as experimental results, measurements,
implementations, full-system and large-scale simulations,
operational experiences, deployment problems, and applications for
challenged networks. We specifically solicit papers in these
respects for the following areas:
* Architecture, design and evaluation of systems that are robust to
high rates of nodal churn, unreliable infrastructure, and
intermittent connectivity due to for instance high mobility, power
saving.
* Characterization of performance and security challenges and
measurements of challenged networks; performance metrics and
measurements thereof; benchmark tests and scenarios of network
challenges.
* Protocol and application design and evaluation with respect to
robustness, security and privacy, as well as quality of service and
experience.
* Configuration, management, monitoring and adaptivity of systems for
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 its community.
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. Papers will be
reviewed single blind. Click here to submit your paper via EDAS:
