In this paper, we propose a new ARQ scheme, named Go-Back-i-symbol (GBi) ARQ scheme which is suitable to Meteor Burst Communications (MBC). The scheme is based on the Viterbi decoding algorithm for convolutional codes and can achieve symbol-wise retransmission, so that it has high throughput performance for packet communication systems over time varying short burst channels such as MBC channels. We...
Multi-hop ad-hoc networks are promising candidates for next generation wireless communications. When using HARQ for multi-hop transmissions, each relay node has to decode received messages and request retransmission to its previous node when it detects errors. Thus, every relay node is required to spend extra power and time because of retransmissions and decodes for collaboration of transmission by...

This paper provides an analysis of throughput performance of an ARQ scheme suitable to multihop wireless transmissions. We firstly introduce the state transition diagram of the ARQ scheme and calculate the throughput performance analytically. Next we examine the throughput performance of the typical three scenarios. The results suggest that the appropriate ARQ scheme can improve the throughput performance...
For reduction in transmission errors on wireless links, we proposed the multi-route coding on multiple routes for wireless multi-hop networks. In the proposed coding, a source node encodes a packet, divides it into sub packets, and transmits them on multiple routes. A destination node combines and decodes the arriving sub packets to get coding and diversity gain. In this paper, we propose a hybrid...
For reduction in bit errors on wireless channels, we proposed the multi-route coding scheme on multiple routes for wireless multi-hop networks. In this paper, we introduce ARQ to the multi-route coding. In the multi-route coding, the destination node combines and decodes sub packets which are encoded and divided by the source node. The intermediate node relays a sub packet, that is, only a part of...
