On the feasibility of a user-operated mobile content distribution network

Abstract

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.

“…We perform tests using traces from content distribution simulations performed in the city of Helsinki [68]. The traces contains 118 DAGs with user polls ranging from 100 to 811 participants.…”

“…A distributed solution to content replication by considering dynamic environments and load balancing is proposed in [12]. The authors in [13] uses the special mobile devices as caching servers in Mobile-CDN architecture. A user-operated content distribution network for the mobile smartphone is proposed in [14] to achieve widespread distribution of heavy content.…”
