BUBBLE Rap: Social-Based Forwarding in Delay-Tolerant Networks
TLDR
We design and evaluate BUBBLE, a novel social-based forwarding algorithm, that utilizes two social and structural metrics, namely centrality and community, to enhance delivery performance. Expand

Pocket switched networks and human mobility in conference environments
TLDR
Pocket Switched Networks (PSN) make use of both human mobility and local/global connectivity in order to transfer data between mobile users' devices. Expand

Impact of Human Mobility on the Design of Opportunistic Forwarding Algorithms
TLDR
We study how the distribution of inter-contact time, that is the time gap separating two contacts of the same pair of devices, exhibits a heavy tail such as one of a power law, over a large range of value. Expand

Mobile Data Offloading through Opportunistic Communications and Social Participation
TLDR
We propose to exploit opportunistic communications to facilitate information dissemination in the emerging Mobile Social Networks (MoSoNets) and thus reduce the amount of mobile data traffic. Expand

Pocket Switched Networks: Real-world mobility and its consequences for opportunistic forwarding
TLDR
We study an ad-hoc network scenario, called opportunistic networking, where inherent mobility and the occasional connection with other devices are used to transfer data. Expand

Cellular traffic offloading through opportunistic communications: a case study
TLDR
We propose three algorithms, called Greedy, Heuristic, and Random, to exploit opportunistic communications to facilitate the target-set selection problem for information dissemination in the emerging Mobile Social Networks (MoSoNets). Expand

Haggle: A networking architecture designed around mobile users
TLDR
We propose Haggle, an asynchronous, data-centric network architecture which addresses this environment by “raising” the API so that applications can provide the network with application-layer data units (ADUs) with high-level metadata concerning ADU identification, security and delivery to user-named endpoints.
