Improving BitTorrent's Peer Selection For Multimedia Content On-Demand Delivery
The great efficiency achieved by the BitTorrent protocol for the distribution
of large amounts of data inspired its adoption to provide multimedia content
on-demand delivery over the Internet. As it is not designed for this purpose,
some adjustments have been proposed in order to meet the related QoS
requirements like low startup delay and smooth playback continuity.
Accordingly, this paper introduces a BitTorrent-like proposal named as
Quota-Based Peer Selection (QBPS). This proposal is mainly based on the
adaptation of the original peer-selection policy of the BitTorrent protocol.
Its validation is achieved by means of simulations and competitive analysis.
The final results show that QBPS outperforms other recent proposals of the
literature. For instance, it achieves a throughput optimization of up to 48.0%
in low-provision capacity scenarios where users are very interactive.Comment: International Journal of Computer Networks & Communications(IJCNC)

ANÁLISE DO PARADIGMA BITTORRENT PARA STREAMING DE VÍDEO SOB DEMANDA NA INTERNET ANTE ACESSO SEQUENCIAL PARTICIONADO SINCRONIZADO
Considering the video-on-demand (VoD) streaming serviceand a mostly sequential-data access pattern by users, thisarticle has the two following goals. Firstly, to analyze theBitTorrent paradigm's eciency under this access-patterntype. Secondly, to propose and analyze a new policy for dataselection by users, denoted as Smart Policy, focused on thisaccess-pattern type. For that, simulations are carried outin dierent VoD streaming scenarios, evaluating a varietyof performance metrics. Compared to previous proposalsin the literature, the nal results highlight optimizationsof up to 24,3% and 100% at the download rate and datawaiting time, respectively.
