With the spatial redundancy provided by the broadcasting nature of wireless channel,network coding shows great potential in ad hoc network application. However,the throughput gain of TCP traffic with network coding keeps low. This paper proposes the model for TCP network traffic based on its selfsimilarity using FARIMA model and then predicts the arriving time interval of data packets for routing nodes,enabling them to make right coding decisions based on the current network situation. The simulation result proves the self-similarity of TCP traffic and the predicting algorithm shows the good performance. In the paper the applying process of the predicting algorithm in COPE on NS2 is introduced in detail.
