For the optimization of computer networks with high bandwidth requirements, wireless network traffic prediction is necessary.
Its goal is to reduce maintenance costs and enhance internet services. Feature selection is a major issue in the Multivariate
Time Series (MTS) Spatio-temporal modeling. Another problem is the dependency between input features, time-lags, and
spatial factor so that an appropriate model is needed. This study aims to provide solutions to two problems. The first is to
improve a feature extraction and selection process in Spatio-temporal MTS data for relevant features using Detrended Partial
Cross-Correlation Analysis (DPPCA) and non-redundant features associated with linear using Pearson's Correlation (PC)
filters and non-linear associations using Symmetrical Uncertainty (SU) and combination of both PCSUF. The second is to
develop a Spatio-temporal framework model using Recurrent Neural Networks (RNN) to get a better performance than
traditional model. These methods are combined and tested using the dataset of cellular networks with one-hour intervals during
November in three locations. Testing the effectiveness of the feature selection technique showed that 27.6% of the total
extracted features. The forecasting model with the DPCCA–SU-RNN combination method gets the best performance by having
RMSE = 380.7, R 2 = 97%, and MAPE = 10%
