摘　　要：在物联网不断发展的过程中,无线网络应用新老技术交替出现,网络兼容性问题成为技术突破的重点核心。由此本文进行异构无线网络的研究,通过协作中继技术实现对网络的优化选择。探讨在异构无线网络选择算法,提出一种基于模糊推理系统的效用函数参数设置方法,解决不同移动终端对有效函数参数的规范化指标问题,分别从单向和双向中继传输系统进行中继定位与功率分配。In the process of the continuous development of the Intemet of things, new and old technologies of wireless network appear alternately. Network compatibility issues become the core of technology breakthrough. This paper studies on the heteroge- neous wireless network, and optimizes the network with cooperative relay technology. It studies on the heterogeneous wireless net- work selection algorithm; puts forward the utility function parameters setting method based on fuzzy inference system, to solve the problem of function parameters index for different mobile terminals, implementing relay positioning and power allocation from one- way and two-way relay transmission systems respectively.
