“…A typical example of such a DTN node is the Liberouter [21], a low-cost router platform that serves as WLAN point. We assume that certain gateways have access to the Internet (online DTN gateways) through a WiFi hotspot that exists in the area provided by the system administrator (e.g., local municipality), while the majority is offline.…”

Delay/disruption-tolerant networking has been exploited in a variety of communication scenarios to provide basic delay-tolerant Internet services. In this paper, we propose a delay/disruption-tolerant networking (DTN)-based architecture for dense urban environments that exploits the existing infrastructure of public transport networks to provide Internet services through applications that can withstand certain delays without significantly affecting user experience. To achieve data delivery within the delay tolerance threshold that each user defines, we couple the proposed architecture with the enhanced connectivity plan routing protocol (CARPOOL+) that includes smart mechanisms for route calculation. In particular, the proposed architecture exploits both scheduled and opportunistic contact opportunities and mitigates the impact of typical delays caused by traffic, road accidents, etc. Our simulation results show that the proposed architecture achieves high delivery ratio with low latency, even when significant delays occur. We also compare CARPOOL+ with the most well-known DTN routing solutions and show that CARPOOL+ achieves the highest delivery ratio with the lowest overhead.

“…Such applications differ from typical web applications in which users enter (e.g., queries), and obtain virtually immediate responses; cloud applications where contents are stored, updated, and maintained consistent in data centers; and conversational applications where messages and media are delivered reliably and virtually instantly. Sample applications include content sharing [16,10], distributed text and voice messaging [8,9], and social networks [17,11].…”

“…1 (3) We instrument legacy nodes connecting to the Liberouters and visiting the web pages to serve as additional message carriers between different Liberouters using cookies and web storage, so that the connectivity between Liberouters increases. While we have presented the Liberouter concept before [11], the contributions of this paper are on its extensions to embrace legacy nodes.…”

Mobile opportunistic networking utilizes device-to-device communication to provide messaging and content sharing mechanisms between mobile users without the need for supporting infrastructure networks. However, enabling opportunistic networking in practice requires a sufficient number of users to download, install, and run the respective routing and application software to provide sufficient node density, and thus connectivity for the network to actually function. In this paper, we explore reaching out to nodes that have not (yet) installed any dedicated software to: (1) allow them to access public content in an opportunistic network to possibly seed their interest and (2) instrument them to assist as (limited) message carriers to improve connectivity. We report on our system design and implementation and offer performance insights gained from simulations and initial experiments.
