Comfort Applications in Vehicular Ad Hoc Networks Based on Fountain Coding

“…1. To solve this problem, many studies have investigated AL-FEC in many communication systems [8,[14][15][16]. AL-FEC covers the packet loss not recovered by channel coding because it is applied above layer 2 and uses the fountain code known as the rateless erasure code.…”

In this paper, we propose a fully reliable file-transfer framework with application layer forward error correction (AL-FEC) in satellite communications on the move (SOTM) systems. In particular, the proposed framework uses a two-way acknowledgement (ACK) exchange mechanism. The proposed framework is implemented into a performance-enhancing proxy to minimize the system change. Furthermore, we analyze the file-transfer time of the proposed framework by Markov chain. The analysis results show that the proposed framework outperforms TCP in terms of the file-transfer time and the goodput. Furthermore, in the transfer of a large-sized file, the overhead of the proposed AL-FEC mechanism is small in terms of the resource efficiency.

Abstract-This paper proposes an implementation of systematic Raptor code in an ad hoc V2V (vehicular-to-vehicular) environment for post-crash safety broadcast. This is to address the latency problem caused by use of repetition code in a high speed vehicular environment for time-sensitive safety applications. The highly dynamic topology and challenging RF behavior of vehicular networks necessitate the use of a robust error control mechanism even with the use of spatial diversity techniques such as STBC-MIMO scheme. A crosslayer simulator model is used to evaluate the delay performance of Raptor codes against a low complexity repetition code. The numerical analysis demonstrates that the end-toend delay performance is significantly reduced when Raptor codes are used, especially at higher distances from the source node. This is true in the case of single antenna as well as multiple antenna schemes.
