Abstract:

The metabolic grey model (MGM) is investigated for network traffic prediction. It is shown that, when the MGM modeling-length is shorter than the traffic primary-period length, the accuracy is satisfactory. Small modeling-length MGM is preferred. Residual grey model (RGM) is not needed for its contribution to accuracy improvement is limited. The prediction of MGM, auto regressive integrated moving average(ARIMA )and Elman neural network(ENN) are compared. The MGM accuracy is better than the ARIMAs, and equals to the ENNs. Furthermore, MGM is adaptive to traffic changes.

Key words: network traffic prediction, grey theory, grey model
