Simulation and performance evaluation of mobility management in UAV self-organizing network
Unmanned aerial vehicle(UAV)networks,which can be dynamically deployed at low cost and provide flexi-ble coverage on demand,can be used as a complement and extension of terrestrial networks to enhance network service performance.However,the high mobility of UAV creates challenge for network optimization and mobility management.The need for mobility management in highly dynamic UAV networks can be met by using self-organi-zing network(SON)technology.This paper refers to the 3GPP standards and technical specifications to construct a simulation platform for UAV self-organizing network from the establishment of self-organizing network to the user ac-cess and handoff,and carry out mobility management simulation and performance evaluation of UAV self-organizing network.The simulation results show that the simulation platform constructed in this paper can realize the self-con-figuration function of the network,and can carry out self-optimization when the parameters are unreasonable,so as to realize better network service performance than the traditional method.
