Application of ARIMA Models for Handoff Control in Multimedia IP Wireless Networks

This paper presents a new approach to prediction of resource demand for future handoff calls in multimedia wireless IP networks. Our approach is based on application of multiplicative ARIMA(p, d, q)x(P, D, Q)S models fitted on traffic data measured in the considered cell itself. The main advantages of the proposed method are the following: first, the prediction model is simple for implementation and second it does not require communication between the adjacent cells. We give a particular attention to design of an adequate model since bad prediction results in overestimation of required resources. Simulation results show the superiority of the proposed approach for some typical nonstationary situations compared with conventional methods.
