Abstract: Resumo-O presente trabalho consiste na proposta de um protocolo de transporte para redes tolerantes a atrasos e desconexões (PTTA). Este protocolo tem o objetivo de oferecer uma maior taxa de entrega das informações em um menor tempo. Para isso, serão utilizados Códigos Fontanais como técnica de correção de erros. Os resultados mostram as vantagens da utilização do protocolo proposto.Palavras-Chave-Redes tolerantes ao atraso, técnicas de codificação, códigos fontanais, The ONE.

A blind mechanism to improve content distribution in delay/disruption tolerant networks

International audienceIn delay/disruption tolerant networks (DTNs), content distribution is performed leveraging on the transient and dynamic contacts between moving users. Such a best effort mechanism is prone to unbounded downloading delays and bad user experience. To cope with these occurences, this paper introduces a novel mechanism to improve content distribution in DTNs. The proposed mechanism is based on the delay tolerant transport protocol and aims at controlling the diversity in the coded information transmission without increasing the use of network resources or including any feedback messages. In order to validate the proposed mechanism, different scenarios have been evaluated using known DTNs routing protocols. The results show significant gains achieved in terms of delivery ratio in all evaluated scenarios, confirming the efficiency and effectiveness of our protocol independently of the lower layer protocols in use
