| Research Abstract |
In this study, ARQ (automatic repeat request) and error correcting schemes for robust network coding in multihop wireless networks are discussed. In network coding, an encoded packet cannot be sometimes decoded because of lack of holding native packets even if it is demodulated without any errors. We propose a novel ARQ scheme using NACK (non-acknowledge). In addition, we propose an error correcting scheme, which can derive route-diversity effect by introducing multiple route coding scheme.
