基于数据骡子的无线传感器网络拓扑控制综述

A survey on the topology of wireless sensor networks based on data MULEs

在节点部署稀疏、环境恶劣和网络不连通等情况下,WSNs(Wireless Sensor Networks)易出现网络孤岛、能量空洞、节能与恶劣环境网络节点部署等问题。针对这些问题,首先结合拓扑控制算法,对基于静态、动态小世界WSNs拓扑控制研究现状分别进行阐述,并在此基础上着重论述了基于动态小世界WSNs拓扑控制——Data MULEs(Data Mobile Ubiquitous LAN Extensions)的拓扑模型构造、最优轨迹、数据转发流程三个研究方向的算法设计与研究现状,基于此,最后指明了未来应开展的研究工作。

WSNs（ Wireless Sensor Networks） can easily encounter issues like network island, energy hole, power efficiency, and deploy nodes in severe environment under the conditions of nodes sparse distribution, severe environment and the disconnection of networks. In order to solve these problems, present research based on static and dynamic small world for topology control of WSNs are illustrated with the topology control algorithm. Moreover, algorithm design and present study status of three research directions： model construction, optimal track, data transfer process based on dynamic small world for topology control of WSNs-Data MULEs （Data Moble Ubiquitous LAN Extensions） are mainly analyzed. Based above, the future research and work are proposed finally.
