“…This approach is highly suitable for the case of ubiCDN presented here as different source (and relay) nodes have different mobility patterns (e.g., office worker vs. bus driver) and will therefore, deliver different amounts of content. In case of scenarios of mutual interest, such as a football match or a music concert, incentives are built among fans of the same team/artist [2].…”

“…They can also support communication and content exchange when the cellular infrastructure is under severe stress [2][22] [23], whereas at the same time, are the only means of communication when the network infrastructure is down or inaccessible due to natural disasters or government censorship. In opportunistic networks, connectivity among devices is intermittent and communication can be very lossy.…”

“…In most of the cases application usage is all about the exchange of content (e.g., news, video-on-demand, emergency announcements), which in many cases can be of interest to multiple participants; e.g., updates on concurrent sports matches, departure times for public transportation after a football match. Furthermore, a very big proportion of the information that users are interested in does not actually require access to the global network, but are rather targeting non-personalised services or information related to a local event (e.g., a football match in [2]). Relaxing the stress to the network by looking for information locally increases the availability of Internet resources to those who do actually require access to remote services.…”

“…Modern smartphone technology is ubiquitous and supports a multitude of D2D connectivity (e.g., Wi-Fi Direct, Bluetooth) and Internet accessibility options (e.g., LTE, Wi-Fi), which can be exploited simultaneously [1] [2]. These connectivity opportunities together with the fact that modern smartphone devices have large amounts of storage available enables client-serverlike communication between mobile devices themselves.…”

“…According to the above statistics, the ratio of "storage capacity to network data allowance" for cell-connected smartphones is roughly equal to 16 (32GBs of storage capacity and 2GBs of data per month), i.e., users can have at least 16 times more data stored in their devices than can send/receive over the mobile/cell network within a month 2 . Adding a 64GB microSD card (presently costed around $20), the ratio of "storage capacity to data cap" skyrockets to 48.…”

Abstract-The vast majority of mobile data transfers today follow the traditional client-server model. Although in the fixed network P2P approaches have been exploited and shown to be very efficient, in the mobile domain there has been limited attempt to leverage on P2P (D2D) for large-scale content distribution (i.e., not DTN-like, point-to-point message transfers). In this paper, we explore the potential of a user-operated, smartphonecentric content distribution model for smartphone applications. In particular, we assume source nodes that are updated directly from the content provider (e.g., BBC, CNN), whenever updates are available; destination nodes are then directly updated by source nodes in a D2D manner. We leverage on sophisticated information-aware and application-centric connectivity techniques to distribute content between mobile devices in densely-populated urban environments. Our target is to investigate the feasibility of an opportunistic content distribution network in an attempt to achieve widespread distribution of heavy content (e.g., video files) to the majority of the destination nodes. We propose ubiCDN as a ubiquitous, user-operated and distributed CDN for mobile applications.

Opportunistic networks can increase network capacity, support collaborative downloading of content and offload traffic from a cellular to a cellular-assisted, device-to-device network. They can also support communication and content exchange when the cellular infrastructure is under severe stress and when the network is down or inaccessible. Fountain coding has been considered as especially suitable for lossy networks, providing reliable multicast transport without requiring feedback from receivers. It is also ideal for multi-path and multisource communication that fits exceptionally well with opportunistic networks. In this paper, we propose a content-centric approach for disseminating content in opportunistic networks efficiently and reliably. Our approach is based on Information-Centric Networking (ICN) and employs fountain coding. When tied together, ICN and fountain coding provide a comprehensive solution that overcomes significant limitations of existing approaches. Extensive network simulations indicate that our approach is viable. Cache hit ratio can be increased by up to five times, while the overall network traffic load is reduced by up to four times compared to content dissemination on top of the standard Named Data Networking architecture.
