Abstract: In this paper, we present a system that enables people to post and receive tweets despite disruptions of existing network infrastructure. Our system opportunistically deploys mobile ad hoc networks (MANETs) based on Wi-Fi in which people can communicate with each other in a peer-to-peer fashion. A MANET per se constitutes an isolated island, but as people carry devices around that can join other MANETs, eventually people can transport previously collected data to the online world. Compared to other systems that aim to enable communication in crisis, our system differs in two ways: it does not rely on existing network infrastructure, and it exploits established protocols and standards allowing it to run on off-the-shelf, commercially available smartphones. We evaluated our prototype with a group of students and practitioners. Overall, we received positive feedback on the potential of our technology, but also were pointed to limitations requiring future work.

Amro Al-Akkad, & Christian Raffelsberger. (2014). How do i get this app? A discourse on distributing mobile applications despite disrupted infrastructure. In and P.C. Shih. L. Plotnick M. S. P. S.R.

Abstract: This paper aims to lead a discourse on distributing mobile applications while having no access to cloud services. While in daily life people acquire applications via application stores, the access to those stores can be severely hampered in disasters. Instead of wishful thinking, i.e. hoping that people or manufactures would pre-install an (emergency) app before a disaster, we have started to investigate into Internet-less deployment mechanisms. We discuss five potential approaches of deploying apps in an ad-hoc fashion. Each approach is assessed against six criteria, while taking a stance that the smartphone is the minimally required deployment platform. This paper concludes with the observation that current mobile operating system providers do not provide “Internet-less” deployment mechanisms, although platforms as Android allow for this. This said, we hope that this contribution can spark further interest into the discussed problematic.
