| Research Abstract |
Nowadays, there is a large demand for new communication systems having high data rate and high reliability using limited resources. In this study, we focus on Automatic Repeat Control techniques. Firstly, new ARQ schemes for multi-hop transmissions based on Packet Combination and Adaptive Relaying are proposed. Next, an ARQ scheme suitable to meteor burst communications, named GBi-ARQ scheme is proposed and evaluated.
