“…The effect of different spraying algorithms and cost reduction of erasure coding were studied [16]. In [17], the authors implemented the epidemic routing with network coding, and to obtain better performance they introduced adaptive scheduling mechanism to ensure that the buffer of nodes is enough for current amount of data. The performance of epidemic routing in presence of network coding in opportunistic networks was compared with the sole use of replication [18].…”

Abstract-Data communication in Vehicular Delay TolerantNetworks (VDTN) poses serious challenges on file transferring due to intermittent connectivity and packet loss. To improve file transfer in VDTN, we propose a mechanism that includes fountain coding in the application layer, UDP in the transport layer, and AODV-DTN in the network layer in our new architecture. Of the characteristics of fountain codes is that the source data can be rebuilt thoroughly from any subset of the encoded packets at destination. Furthermore, no feedback is required to guarantee reliable delivery. Therefore, we use UDP in contrast to classical use of TCP, while reliability is still preserved. A new routing algorithm, named AODV-DTN, is presented and developed in the network layer based on AODV and Store-Carry and Forward policy. The cross-layer mechanism is used as an alternative to preliminary layer design so as to develop communication between the network layer and application layer. We have conducted extensive simulations to evaluate the performance of our architecture. The results show that our architecture outperforms in terms of file delivery ratio and byte throughput when compared with FOUNTAIN and classic FTP scenarios. In addition, the negative effect of increasing file size is mitigated in the proposed architecture in comparison to other alternatives. It is shown that for delay tolerant and long-distanced inter-RSU communications the proposed architecture behaves sufficiently well.

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.
