摘要:

在分析现有链路质量预测模型的基础上,提出基于深度信念网络的无线传感器网络链路质量预测模型。采用支持向量分类机对链路质量进行评估,获得链路质量等级;采用深度信念网络提取链路质量特征,并采用softmax预测下一时刻的链路质量。在不同实验场景下,与逻辑回归、BP神经网络以及贝叶斯网络预测模型相比,所提出模型具有更好的预测准确率。

关键词: 无线传感器网络, 链路质量预测, 深度信念网络, 链路质量等级

Abstract:

After analyzing the existing link quality prediction models,a link quality prediction model for wireless sensor network was proposed,which was based on deep belief network.Support vector classification was employed to estimate link quality,so as to get link quality levels.Deep belief network was applied in extracting the features of link quality,and softmax was taken to predict the next time link quality.In different scenarios,compared with the model of link quality prediction based on logistic regression,BP neural network and Bayesian network methods,the experimental results show that the proposed prediction model achieves better precision.

Key words: wireless sensor network, link quality prediction, deep belief network, link quality level
