- Abstract
In urban commercial areas covered by dense heterogeneous wireless networks, to address the problems of uneven network load caused by concurrent handover of large number of terminals and insufficient use of network similarity, we propose a handover decision algorithm based on network grouping. First, the collected and initialized network parameters are input into the network grouping model, and the similarity of network performance is used to obtain the network group. Secondly, the target network group is selected based on the firework algorithm according to the preference type of the terminal. Thirdly, the intersection of the terminal accessible network set and the target network group is solved to obtain its candidate network set, from which the network with the largest performance factor is selected as the target network to perform handover, and the network group is dynamically updated. Finally, the analysis of the simulation results shows that the algorithm can reduce the handover blocking rate, increase the system throughput, and improve the quality of terminal service under the premise of balancing the network load.
