Major wireless operators are nowadays facing network capacity issues in striving to meet the growing demands of mobile users. At the same time, 3G-enabled devices increasingly benefit from ad hoc radio connectivity (e.g., WiFi). In this context of hybrid connectivity, we propose Push-and-track, a content dissemination framework that harnesses ad hoc communication opportunities to minimize the load on the wireless infrastructure while guaranteeing tight delivery delays. It achieves this through a control loop that collects user-sent acknowledgements to determine if new copies need to be re-injected into the network through the 3G interface. Push-and-Track is flexible and can be applied to a variety of scenarios, including periodic message flooding and floating data. For the former, this paper examines multiple strategies to determine how many copies of the content should be injected, when, and to whom; for the latter, it examines the achievable offload ratio depending on the freshness constraints. The short delay-tolerance of common content, such as news or road traffic updates, make them suitable for such a system. Use cases with a long delay-tolerance, such as software updates, are an even better fit. Based on a realistic large-scale vehicular dataset from the city of Bologna composed of more than 10,000 vehicles, we demonstrate that Push-and-Track consistently meets its delivery objectives while reducing the use of the 3G network by about 90%. $ This article is an expanded version of work presented at the 12 th IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM 2011) [1]. This paper provides greater details and presents all-new results based on different scenarios (e.g., floating data), and different assumptions (e.g, vehicle participation ratio).

“…This formal separation of communication into a delay-tolerant data channel and an end-toend control channel brings robustness to our design; as we will see, the control channel can be used for route updates or user mobility, which are otherwise hard tasks in a purely delay-tolerant environment. The SMS control channel itself can run either off a cellular data card, or even a GSM cell phone mounted as a modem Oliver [5]. Using SMS instead of a data connection over GPRS is simpler because nodes can then directly exchange low-bandwidth information with each other using phone numbers, and do not have to deal with dynamically assigned IP addresses or bypassing NATs.…”

Rural Internet kiosks in developing regions can cost-effectively provide communication and information services to the poorest sections of society. Yet, a variety of technical and non-technical issues have caused most kiosk deployments to be economically unsustainable. KioskNet addresses the key technical problems underlying kiosk failure by using robust 'mechanical backhaul' for connectivity, and by using low-cost and reliable kiosk controllers to support services delivered from one or more recycled PCs. KioskNet also addresses related issues such as security, user management, and log collection. In this paper, we describe the KioskNet system, outlining its hardware, software, and security architecture. We describe a pilot deployment and how we used lessons from this deployment to redesign our initial prototype.
