针对卫星通信网络的特点,提出了一种卫星异构网络环境下的网络选择策略。算法考虑不同业务类型的QoS需求、用户偏好、网络负载等因素,利用层次分析法确定影响网络选择的因素的权值,计算出每个可用网络的综合性能,确定最佳接入网络。仿真结果表明,该算法能够较好地适应卫星异构网络环境,提高网络选择的准确性和有效性。
Aiming at the characteristics of satellite communication network, a network selection strategy is proposed in the environment of satellite heterogeneous network. The algorithm considers the QoS requirements, user preferences, network load and other factors of different service types. It uses AHP to determine the weight of the factors affecting the network selection, and calculates the comprehensive performance of each available network to determine the best access network. Simulation results show that this algorithm can better adapt to the heterogeneous network environment of satellite and improve the accuracy and effectiveness of network selection.
