Throughput enhancement for short packets in the wireless packet networks

We propose a novel transmission scheme suitable for short packet transmission over wireless channels. The proposed scheme is characterized by two schemes: 1) multicopy transmission per transmission payload and 2) multiple fragmented packet (referred to as minipacket) transmission. The multicopy transmission is to mitigate the transmission inefficiency of short packets and improve the decoding probability at the receiver. On the other hand, the minipacket transmission is to avoid the retransmission of correctly received symbols. By implementing the proposed scheme into the traditional IEEE 802.11b WLAN system, simulation results show the improved system throughput and reduced packet transmission time.
