摘要
In this paper, a novel load balancing scheme is conceived for the OFDMA LTE cellular and WiFi coexisted network. The mobile index is introduced to measure the mobility of user equipments (UE) in the coverage of WiFi hotspots and the access index is calculated by considering both mobile index and the received power from WiFi access points (AP) to determine the UE's access pattern. The load balance entity manages the UE load in coexistent network dynamically. A load balancing algorithm is developed to balance the network load measured by the ratio of the average WiFi load to the LTE cell load as well as the Jain's fairness index. Simulation results demonstrate the proposed algorithm can acquire an improvement in network load balancing, thus enhancing the overall system throughput.
