【摘要】：无线传感网络(Wireless Sensor Network,WSN)诞生于上个世纪八十年代,并以其独特的优势被应用于社会的各个领域。与传统的网络不同,WSN是一个由大量的传感器节点通过自组织的方式构建成的网络,这些节点一般能量都十分有限,经常会因为能耗过度而死亡。针对WSN节点能量受限这一特点,本论文结合网络编码技术,对基于网络编码的WSN路由算法进行了深入的研究,主要工作可以概括为:(1)设计了一种基于网络编码的WSN分层多跳路由协议。首先,以节点与汇聚节点的距离作为依据,把整个网络划分为一个多层的结构。其次,在数据传输的过程中加入了随机线性网络编码。本文从理论和仿真的角度,分析了在数据传输过程使用网络编码较不使用网络编码在节约能耗上的优势。(2)提出了一种基于网络编码的WSN分簇路由协议。首先,在构建簇的过程中充分考虑了通信距离对于信道质量的影响,为了保证良好的通信质量对簇的规模做出一定限制。其次,将网络编码应用到簇头的数据传输过程中,减少了簇头节点发送数据的次数。建立了节点的发送功率和网络总功率的函数关系,并给出了使得网络总功率最小的最优节点发送功率。最后通过仿真证明了了该协议在节约能耗上的优势,并且对影响该协议性能的几个因素进行了验证。
[Abstract]:Wireless Sensor Network (WSN), which was born in the 80s of last century, is applied to all fields of society with its unique advantages. Unlike traditional networks, WSN is a network constructed by a large number of sensor nodes in a self-organizing way. These nodes are generally very limited in energy, often because of their limited energy. In order to overcome the excessive energy consumption and death. Aiming at the characteristic of energy limitation of WSN nodes, this thesis combines network coding with network coding to make a thorough study of WSN routing algorithm based on network coding. The main work can be summarized as follows: (1) a WSN layered multi hop routing protocol based on network coding is designed. First, the distance between nodes and converged nodes As a basis, the whole network is divided into a multi-layer structure. Secondly, the random linear network coding is added to the process of data transmission. From the theoretical and simulation point of view, this paper analyzes the advantages of using network coding rather than network coding in the data transmission process to save energy. (2) a network coding based on network coding is proposed. First, in the process of building the cluster, the influence of the communication distance on the quality of the channel is fully considered. In order to ensure a good communication quality, the size of the cluster is limited. Secondly, the network coding is applied to the cluster head in the data transmission process, and the number of data is reduced by the cluster head node. A node is set up to establish a node. The relationship between the transmission power and the total power of the network is given, and the optimal node transmission power is given to minimize the total power of the network. Finally, the advantages of the protocol in energy saving are proved by simulation, and several factors that affect the performance of the protocol are verified.
