The prediction of mobile data traffic based on the ARIMA model and disruptive formula in industry 4.0: A case study in Jakarta, Indonesia

Abstract

Disruptive technologies, which are caused by the cellular evolution including the Internet of Things (IoT), have significantly contributed data traffic to the mobile telecommunication network in the era of Industry 4.0. These technologies cause erroneous predictions prompting mobile operators to upgrade their network, which leads to revenue loss. Besides, the inaccuracy of network prediction also creates a bottleneck problem that affects the performance of the telecommunication network, especially on the mobile backhaul. We propose a new technique to predict more accurate data traffic. This research used a univariate Autoregressive Integrated Moving Average (ARIMA) model combined with a new disruptive formula. Another model, called a disruptive formula, uses a judgmental approach based on four variables: Political, Economic, Social, Technological (PEST), cost, time to market, and market share. The disruptive formula amplifies the ARIMA calculation as a new combination formula from the judgmental and statistical approach. The results show that the disruptive formula combined with the ARIMA model has a low error in mobile data forecasting compared to the conventional ARIMA. The conventional ARIMA shows the average mobile data traffic to be 49.19 Mb/s and 156.93 Mb/s for the 3G and 4G, respectively; whereas the ARIMA with disruptive formula shows more optimized traffic, reaching 56.72 Mb/s and 199.73 Mb/s. The higher values in the ARIMA with disruptive formula are closest to the prediction of the mobile data forecast. This result suggests that the combination of statistical and computational approach provide more accurate prediction method for the mobile backhaul networks.

“…ARIMA has been developed in 1970 by Box and Jenkin. ARIMA is one of the best fit models for short-term forecasts [56] and is an active predictor that relates past and current with future estimates [57]. Many separated micro and macrodynamics have been tested using the ARIMA model.…”

“…Jiang and Zhang employed a hybrid model combining ARIMA with artificial neural network (ARIMA-ANN model) in order to improve the stock price prediction of highly developed capital markets [59]. A statistical and computational approach engaging ARIMA with disruptive formula has been adapted by Arifin and Habibie in order to have more accurate mobile data traffic prediction in a world full of disruptive technologies [56]. Moreover, ARIMA plays a key role in predicting the outputs of technologies, society, industry studies, and behavioral finance, particularly once it is upgraded as a hybrid model.…”

Linear regression models with autoregressive integrated moving average errors for measurements from real time kinematics-global navigation satellite system during dynamic test

“…The model errors and parameters were used to study the safety of the bridge during GPS measurements. Recently, ARIMA was integrated with other machine learning methods for forecasting in [21]- [23]. Salma et al [24] combines variational mode decomposition techniques with ARMA on GNSS time series data to forecast ionospheric delay.…”

Forecasting LTE Network Traffic Using Hot-Winter’s Multiplicative Seasonal Method and Rolling Forecasting for Telecommunication Company Investment Optimization in Indonesia

“…In planning telecommunications networks, inaccurate forecasting of traffic growth can lead to issues. Forecasting results that underestimate the volume of traffic may result in bottlenecks that reduce the network's capacity to accommodate users, potentially leading to decreased revenue for the company [11]. On the other hand, forecasting errors that result in overly high LTE traffic predictions can lead to wasted resources invested by the company in low-demand areas.…”
