摘要

为了提高异构网络中的网络选择质量，提出了一种基于主客观综合权重的异构网络选择算法。针对不同的服务类型，采用层次分析法计算主观权重。根据网络的实时属性参数，采用改进的CRITIC算法计算目标权重。最后，应用TOPSIS算法选择最优接入网。仿真结果表明，本文提出的算法能够根据用户主观偏好和网络性能找到最优网络。在满足QoS要求的同时，减少了切换次数。

A Heterogeneous Network Access Selection Algorithm Based on Improved CRITIC

In order to improve the quality of network selection in heterogeneous networks, a heterogeneous network selection algorithm based on the objective and subjective synthetic weights is proposed. For different service types, AHP is used to calculate the subjective weights. According to the real-time attribute parameters of networks, the improved CRITIC is used to calculate the objective weights. Finally, the TOPSIS is applied to select optimal access network. The simulation results show that the algorithm proposed in this paper can find the optimal network based on user subjective preferences and network performance. In addition, it can reduce the handoff times while satisfy the QoS requirement.
