BUBBLE Rap: Social-Based Forwarding in Delay-Tolerant Networks

P. Hui, J. Crowcroft, E. Yoneki
Computer Science
IEEE Transactions on Mobile Computing
26 May 2008

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

Proceedings IEEE INFOCOM . 25TH IEEE…
23 April 2006

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

B. Han, P. Hui, V. Kumar, M. Marathe, Jianhua Shao, A. Srinivasan
Computer Science
IEEE Transactions on Mobile Computing
1 May 2012

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

How Small Labels Create Big Improvements

P. Hui, J. Crowcroft
Computer Science
Fifth Annual IEEE International Conference on…
4 December 2006

It is widely believed that identifying communities in an ad hoc mobile communications system, such as a pocket switched network, can reduce the amount of traffic created when forwarding messages, but… Expand

Pocket Switched Networks: Real-world mobility and its consequences for opportunistic forwarding

A. Chaintreau, P. Hui, J. Crowcroft, C. Diot, R. Gass, J. Scott
Computer Science
1 August 2005

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

B. Han, P. Hui, V. Kumar, M. Marathe, Guanhong Pei, A. Srinivasan
Computer Science
CHANTS '10
24 September 2010

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

J. Scott, J. Crowcroft, P. Hui, C. Diot
Computer Science
18 January 2006

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.
