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:
