This demo presents Oi!, an opportunistic data transmission tool. Implemented on Android and available as open source, Oi! relies on social interaction, device-to-device short-range wireless transmission, as well as on history of contact duration to perform opportunistic data transmission. In this demo we show how Oi! can be used with intermittent I...

... is responsible for detecting the presence of neighboring devices for the purposes of social weight compu- tation carried out by the Social Proximity module. As illustrated in Fig. 9, BT starts by initializing the Bluetooth communication interface (1) and registering the framework UUID (2). This UUID is used to identify among the neighboring devices those which are actually running the framework. Then, BT shifts to the idle state (3), where it expects for one of the four actions to take ...

The 802.11 networks (wireless fidelity (WiFi) networks) have been the main wireless internet access infrastructure within houses and buildings. Besides access point placement, building architectures contribute to the WiFi signal spreading. Even dough WiFi installation in buildings becomes prevalent; the building architectures still do not take WiFi...

In this paper, we present a study to realize a low-cost sustainable Wireless Internet Service Provider (ISP) built for rural areas of developing countries. There was no Internet access in the area prior to...

This poster describes DABBER, a protocol developed to extend the reach of Named Data Networking into wireless environments. Our key contribution lies in the fact that DABBER supports communication in op-portunistic wireless environments by relying on routing metrics that take into consideration node availability and centrality measures; data reachability metrics. The poster provides an overview to the DABBER architecture , and to the available open-source implementation.

... However, we refrain from a deep analysis at these solutions since: i) separately, they do not bring any relevant knowledge for the development of CIMPL; ii) some of them provide too basic mechanisms (e.g., simple data exchange; help users analyze images instead of analyzing such images themselves); and iii) we are interested in solutions that actually bring these worlds together as intended with CIMPL. There is, however, a recent application, Oi! [5], that allows for opportunistic dissemination based on how users socially engage. This is rather interesting and can further complement CIMPL since its users do have social interactions that can be considered to improve the dissemination of public safety data (the potetial of social-based solutions are discussed on Sec. 4). ...
... For that, the OpenCV computer vision library shall be considered along with the adapted version of the TagActivity to allow the recognition of the authority to be notified upon the reporting of photo incident through the CIMPL application. Another potential future work concerns the employed opportunistic dissemination approach as the one employed by Oi! application [5] . The current version of CIMPL relies on an epidemic solution implemented at the WiFiDirect module , which is enough for the purpose of the application. ...
Public safety plays an important role in what concerns the social welfare of citizens, thus impacting their quality of life. There are different mechanisms (e.g., police, firefighters) in place to help citizens feel safe, and the citizens themselves may have a more proactive posture (e.g., neighborhood watch). The proposed Android application, called CIMPL, targets the willingness of these model citizens in engaging in public safety efforts and the capabilities of their mobile personal devices to improve social welfare. CIMPL allows users to opportunistically exchange public safety content among their devices. This content, produced by users, identifies potential hazard situations, and is used to duly notify the authorities involved in the maintenance of public safety.
... Normally, Bluetooth and Wi-Fi Direct are readily available and shall serve for the realization of PSNs and respective routing solutions. The Oi! Android application [148] is an example of a PSN solution that relies on both Bluetooth and Wi-Fi Direct to allow users to opportunistically exchange messages based on their level of social interaction. In this case, Bluetooth is used to capture the social proximity among user devices, while Wi-Fi Direct allows for the exchange of messages among socially wellconnected nodes based on dLife [28]. ...
A pocket switched network (PSN) is dynamically formed by people who carry portable handheld devices. Interest in PSNs is driven by the increasing number of handheld devices, the several wireless interfaces they possess, as well as their ability to store, carry and forward data. The lack of fixed network topology distinguishes PSNs from traditional networks, and unlike other types of mobile networks, nodes in PSNs closely follow human movement patterns. As a result, PSNs are faced with new challenges especially in the aspect of routing. Although various routing protocols have been proposed, most of them focus on optimizing the performance of networking primitives for traditional networks such as unicast, broadcast and multicast. However, these primitives themselves appear to be insufficient due to new application opportunities presented by PSNs. This paper adopts a user scenario based approach to determine the current state of PSN routing protocols. Specifically, four modes of data transfer are established from six generalized PSN user scenarios. Due to the wide range of existing routing proposals, a new taxonomy is proposed to facilitate analysis of their compatibility with the established modes of data transfer. The analysis provides new insights into application based routing approaches for realizing next-generation PSN routing protocols.
This draft describes the Data reAchaBility BasEd Routing (DABBER)
protocol. DABBER aims to provide a name-based routing solution to
support the operation of Information-centric Networking frameworks in
opportunistic wireless networks. By "opportunistic wireless
networks" it is meant multi-hop wireless networks where finding an
end-to-end path between any pair of nodes at any moment in time may
be a challenge. The goal is to assist in better defining
opportunities for the transmission of Interest packets in a store-
carry-and-forward manner, based on a proactive approach. The
document describes how to integrate DABBER in a networking node that
implements some ICN approach, such as Named-Data Networking (NDN) or
Content Centric Networking (CCN), along with the specification of the
proactive approach based on the dissemination of name-prefix
information.
