Abstract

Network coding is a promising technology that increases the system throughput via reducing the number of transmissions for the packets delivered from the source node to the destination node in the saturated traffic scenario. Nevertheless, some packets can suffer from the metric of end-to-end delay. Since it takes the queuing delay at the intermediate node to wait for other packets to be encoded with (XOR). Therefore, in this paper, we analyze the delay according to the packet arrival rate and propose an enhanced network coding scheme, iXOR (Intelligent XOR). It reduces the average delay even under unsaturated traffic load through the holding-x strategy. Through an analysis and extensive simulations, we show that iXOR is better than the general forwarding scheme (FWD) without XOR and the XOR without the holding-x strategy, x=0, in the aspect of the average delay as well as the delivery ratio.
