摘要
移动终端通信网络节点能量有限,采用当前链路选取方法对链路进行选择,需要将大量数据包作为测试样本,不仅能耗高,而且会导致通信效率大大降低。提出一种新的移动终端通信网络传输链路快速选取方法,介绍贝叶斯估计原理,对链路质量进行估计。假设节点选择备选链路集合中所有链路的概率是相等的,经k轮探测后,贝叶斯估计通过新增样本对应的链路质量进行估计,在此基础上引入优选机制,将质量估计结果最高的链路赋予最高的概率,将质量估计结果较低的链路赋予较低的概率,实现移动终端通信网络传输链路的快速选取。实验结果表明,所提方法不仅能够保证链路传输的正确性和完整性,而且链路选取速度快,具有很好的节能效果。
Mobile communication network node energy limited,the use of the current link selection method to select the link,to a large number of data packets as test samples,not only high energy consumption,and can lead to communication efficiency is greatly reduced. A new mobile communications network transmission link fast selection method was put forward. The principle of bayesian estimation of link quality estimation was introduced,hypothesis node selection optional link probability are equal,all the links in the collection after k wheel probe,bayesian estimation by new samples of the corresponding link quality estimation,on the basis of introducing the optimization mechanism,to estimate the results of the highest quality link gives the highest probability,gives lower link quality estimation results to low probability,to realize fast selection of mobile communication network transmission link. The experimental results show that the proposed method can not only guarantee the correctness and completeness of the link transmission,selection and link speed,has the very good energy saving effect.
