近年来,无线传感器网络(Wireless Sensor Network,WSN)作为物联网底层网络应用的基础技术之一,受到国内外的关注。由于WSN具有成本低、功耗小且大面积分布的特点,在安全监控、物流仓储、军事战争、环境监测、医疗护理等领域得到广泛的应用。然而无线传感器网络的能量、计算能力、通信能力都有限,需要采用高效的路由协议来实现对数据的高效传输并降低系统的能量消耗。本文首先对WSN路由协议进行研究,针对EDCS算法和ESEP算法在簇的形成和数据传输方面的缺点,提出了异构无线传感器网络非均匀分区多跳路由协议(Unequal Clustering and Multi-hop Routing Protocol of HWSN,HUCM)。作者的主要研究工作与成果如下:1.分析总结了几种典型的路由协议的优缺点;2.对EDCS算法和ESEP算法进行了详细研究,仿真分析结果表明:(1)EDCS算法在簇头的选举及扩展性等方面较平面路由协议有一定的先进性,但同时也存在一些问题:建立的簇大小是不确定的,采取单一的单跳的数据传输方式,这些特点会使网络能耗加大,加快网络的失效;(2)ESEP算法适用于三级异构的网络,未考虑剩...
【英文摘要】
In recent years, Internet of things technology has been booming, and wireless sensor network(WSN), as one of the main technology of the underlying network of The Internet of things, has been concerned with the study of many experts and scholars at home and abroad. Since WSN has the characteristics of low cost, low power consumption and a large area of distribution, it has a very high application value in security monitoring, warehousing, the military, environmental monitoring, medical care and other areas. ...
