Load Balancing Algorithm for Heterogeneous Wireless Networks Based on Motion State Estimation

Abstract

Different wireless access technologies are complementary in terms of coverage and data transmission rate. Some areas are often covered by multiple wireless access networks at the same time. In some crowded places, the user's movement state has a certain regularity. Therefore, a heterogeneous network load balancing algorithm based on motion state estimation is proposed. The user's motion state is estimated first, and then part of the load is transferred from the cellular network to the WLAN according to the estimation result. The results show that the proposed algorithm can effectively balance the load between heterogeneous networks and improve system efficiency.
