“…Rateless codes, also known as fountain codes, for valueadded services have been proposed in fixed wireless [1]- [3] as well as mobile wireless networks [4]- [6]. This is motivated by its robustness to network dynamics due to the code universal property in the sense that it operates near-capacity for any channel erasure probability less than 1 [7].…”

Abstract-One of the important applications to be available in vehicular ad-hoc networks are value-added or infotainment services. However, vehicular communication suffers from high packet loss due to challenging channel characteristics such as huge Doppler spread and multipath fading. This makes current IEEE 802.11p standard for vehicular network based on the ARQ scheme inefficient. Therefore, the highly scalable and fault-tolerant properties offered by rateless code makes this a promising area of research. This paper investigates the implementation of a systematic Raptor codes for a broadcast service in infrastructureto-vehicular communications. The code performance in terms of the decoding probability of success, mean decoding time and mean aggregate throughput are presented.

“…Fountain codes have also been proposed as the AL-FEC for file transfer in WLANs [3] and VANETs [4]. Normally, File Transfer Protocol (FTP) requires a TCP transport protocol for a reliable and in-order data transmission which is timeinefficient especially in lossy networks such as WLANs and VANETs.…”

File transfer in Vehicular Delay Tolerant Networks using fountain coding

et al. 2013

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.

“…In [2], a data dissemination technique based on fountain codes for vehicular ad hoc networks was conducted. Fountain codes were also invoked in wireless networks to protect file transfer by considering 802.11 Media Access Control (MAC) retransmission rate in [3]. Due to the expense of redundancy, it was observed that fountain codes can improve the performance of data transmission only when considering the actual application environment in [4].…”

Abstract. Video transmission over wireless multi-hop networks is challenging due to the varying nature of the wireless channel as well as the inherent difference between the video data traffic and the general data traffic. A single bit error in a packet may lead to the packet loss, which results in poor quality of the entire video frame. In this paper, we first analyze the effect of payload length on the overhead of bit error, video frame reassembly and network efficiency. Then, to improve the quality of video transmission, we propose an adaptive payload length algorithm based on the digital fountain codes while take transmission efficiency into account. The simulation environment is also designed to evaluate the performance of multi-hop video transmission, which is based on the ARM embedded system. Numerical simulations show that adaptive payload length algorithm can improve the quality of video transmission over wireless multi-hop networks.
