| 要約 |
In an ad hoc network, routes may concentrate on a particular node, and this node will become a bottleneck. In this case, smooth transmission is disturbed. As one solution, in order to mitigate this situation, network coding has been studied. In the network coding, in order that a receiver decodes a packet encoded by a sender, the receiver has to hold all data packets multiplexed in the encoded packet except for the intended data packet. Because the receiver decodes the encoded packet by using packets previously received in promiscuous mode, it might not to hold some of them and cannot decode the encoded packet. In this paper, we propose a packet transmission method using NACK. This method selects (re)transmitted packets among packets in both output queue and retransmission queue by using the ACK and NACK information from the receivers. From the result of the computer simulation, we show that overflow rate can be improved by our proposed method. |
