Abstract

It is our great pleasure to welcome you to the 2014 ACM Workshop on Challenged Networks -- CHANTS'14. Over the years, CHANTS has emerged to be a reference forum that brings together researchers from academia, industry, and government laboratories, in order to present cutting-edge work and results in various aspects of challenged networks. Typical aspects considered by the CHANTS community include very high delays, such as in inter-planetary networks, limited power, such as in sensor and wildlife monitoring networks, communication in settings that lack infrastructure, such as rural and remote areas, and military battlefields, or simply usual environments (urban, rural) where it is difficult or expensive to use the existing infrastructure (e.g., when roaming). Following recent trends CHANTS is also looking at mobile cloud computing, challenged networks in the IoT perspective, data-centric communications, traffic offloading from cellular networks, opportunistic and participatory sensing, green networking. Essentially, challenged networks are found in everyday settings, when access to traditional infrastructure is non-existent, restricted, expensive, overly complex or rapidly changing.

After the success of the previous Workshop on Delay-tolerant Networking (WDTN-05) and eight previous installments of CHANTS (2006-2013), this year CHANTS takes place jointly with ACM MobiCom 2014 in Maui, Hawaii, USA.

In response to the call for papers, we received a total of 37 submissions from Asia, Europe, and the United States, well distributed across the various workshop topics. This confirms that after several years CHANTS continues to be a reference forum by the community of researchers working in this field. After the review phase, the Technical Program Committee accepted 10 submissions as full papers, and 5 more as concise contributions. We also accepted 3 demo submissions. We are very pleased to present a well-balanced conference program that includes one keynote speech, given by Prof. Giovanni Pau (LIP6-UPMC, Paris, France), 3 full-paper sessions, 1 concise contributions session, and a demo session.

Flooding data in a cell: is cellular multicast better than device-to-device communications?

A natural method to disseminate popular data on cellular networks is to use multicast. Despite having clear advantages over unicast, multicast does not offer any kind of reliability and could result costly in terms of cellular resources in the case at ...

Adaptive data offloading in opportunistic networks through an actor-critic learning method

Nowadays, the growing popularity of mobile phones has resulted in an exponential growth of mobile data, causing severe traffic overload in the cellular network. A promising approach to overcome this problem is offloading, i.e. to delegate part of the ...
