摘要

终端接入的网络需要满足各类业务需求，对此提出了一种基于协同学的异构无线网络选择算法。该算法将终端网络选择看作一个系统化的问题，可选网络是一个复合系统，终端上运行的每一种业务都是一个子系统，依据熵的概念得到复合系统的熵值，熵值的大小反映了子系统之间的协同度，进而体现了网络的整体性能。仿真结果表明，在终端多业务的情况下，基于所提算法选择的网络业务QoS满意率达到了95%，比基于TOPSIS算法选择的网络业务QoS满意率提升了近4倍，能够很好地解决多业务终端网络选择问题。

Abstract

A network selection algorithm based on synergetic for heterogeneous wireless network was proposed. The algorithm considered the network selection as a systematic problem. The optional network was a composite system and each kind of service running on the terminal was a subsystem. The entropy of the composite system was obtained according to the concept of entropy and it can reflected the degree of coordination among the subsystems

which in turn reflected the overall performance of the network. The simulation results show that the QoS satisfaction rate of services based on the proposed algorithm is 95%

while the QoS satisfaction rate of services based on the TOPSIS algorithm is only 25%

and the performance of the former is improved by nearly four times

indicating that the problem of multi-service terminal network selection can be solved by the proposed algorithm.
