Information Transmission Quality Optimization and Simulation of Multi-Channel Internet of Things

对物联网信息传输质量问题的研究,能够有效加强多信道物联网运行稳定性。对多信道物联网信息传输质量的优化,需要求出权值拟合代价函数,保证参数估计全局收敛性,完成物联网信息传输质量的优化。传统方法分析映射过程造成的量化误差,对二值灰度图像进行分解,但忽略了对参数估计全局收敛性的控制,导致信息传输质量优化效果不理想。提出多信道物联网信息传输质量优化方法。找出相应的多个近邻,求出多个近邻相应的权值拟合代价函数,保证参数估计全局收敛性,集中多个近邻相应的权重值拟合代价函数,将其转变为凸问题,构造循环最小化,保证信息传输参数估计的全局收敛性,修正时域质量优化方法,使其具有更高的优化精度。实验结果表明,所提方法对信息传输质量优化,且实用性较强。

A method for optimizing the quality of information transmission in multi-channel Internet of things is proposed. Firstly, several neighbors are found to calculate weighting and fitting cost-function corresponding to multi- ple neighbors. The global convergence of parameter estimation is ensured. Centralizing a number of weighting and fit- ting cost-functions corresponding to neighbors, we transform them into a convex problem. Then, the cycle is mini- mized, the global convergence of parameter estimation in information transmission is ensured. Moreover, the method for optimizing time domain quality is modified, which has high precision of optimization. Experimental results show that the proposed method can optimize quality of information transmission, which has strong practicability.
