Abstract: In order to reduce the transmission delay of the data packet in the wireless network, so as to improve the performance of the network, this paper puts forward the CGAR algorithm of the coding gain aware routing protocol. The algorithm uses the network coding gain and expected transmission count of the wireless link, provides the time needed for the node to transmit a data packet from the new flow in the wireless link, and take it as the routing metrics. This metric takes into consideration the factors such as the transmission delay, the time of the node’s contention channel and so on. The experimental results show that this algorithm can reduce the transmission delay of the data packet and improve the performance of the network.
