Abstract
The characteristics of communication in mobile ad hoc networks (MANETs) such as channel fading, limited bandwidth, and interference, bring challenges to reliable data transmission. In this paper, we propose a reliable transmission scheme for multi-hop MANETs, called Fountain code-based Hop-by-Hop Reliable Data Transfer (FHRDT). FHRDT is a hybrid transmission scheme in which the end-to-end transmission mechanism is used for reliability and the hop-by-by mechanism for enhanced efficiency. In addition, the intermediate nodes generate recoded packets without complete decoding of the block which further increases throughput. The simulation results demonstrate that FHRDT performs better than the existing schemes in terms of both end-to-end delay and throughput.
