物联网中的一种改进的Leach的数据融合路由协议的设计

Design of an Improved Leach Data Fusion Routing Protocol in the Internet of Things

物联网中的路由协议一直都是无线传感中的数据融合的重要组成部分,针对Leach路由协议中存在簇头节点选择随机性,簇头节点能量消耗过早以及簇头节点与Sink节点距离无法准确确定等缺点,采用了样本方差值优化分簇数量;引入beat信任模型来确定簇内节点能量的选择;采用关系值来考虑节点到Sink节点中的距离的选择等三个步骤。仿真实验表明,本文的路由协议与Leach协议在失效节点数量,节点能量消耗以及Sink节点数据量等方面有了明显的提高。

Routing protocol in the IOT has always been an important part of data fusion in wireless sensing. Aiming at the random selection of cluster node in the Leach routing protocol, early energy consumption of the cluster node and the difficulty in accurately determining the distance between cluster node and the Sink node, three steps are taken: the amount of sample variance optimal cluster is adopted;the beat trust mode is introduced to determine the selection of node energy within the cluster; and relationship value is adopted to choose the distance between node and the Sink node. The simulation experiment shows that routing protocol in this paper and the Leach protocol have been significantly improved in the amount of disabled nodes, node energy consumption and the amount of Sink node data.
