【摘要】：無線傳感網(wǎng)絡(luò)(Wireless Sensor Network,WSN)誕生于上個世紀(jì)八十年代,并以其獨(dú)特的優(yōu)勢被應(yīng)用于社會的各個領(lǐng)域。與傳統(tǒng)的網(wǎng)絡(luò)不同,WSN是一個由大量的傳感器節(jié)點(diǎn)通過自組織的方式構(gòu)建成的網(wǎng)絡(luò),這些節(jié)點(diǎn)一般能量都十分有限,經(jīng)常會因?yàn)槟芎倪^度而死亡。針對WSN節(jié)點(diǎn)能量受限這一特點(diǎn),本論文結(jié)合網(wǎng)絡(luò)編碼技術(shù),對基于網(wǎng)絡(luò)編碼的WSN路由算法進(jìn)行了深入的研究,主要工作可以概括為:(1)設(shè)計(jì)了一種基于網(wǎng)絡(luò)編碼的WSN分層多跳路由協(xié)議。首先,以節(jié)點(diǎn)與匯聚節(jié)點(diǎn)的距離作為依據(jù),把整個網(wǎng)絡(luò)劃分為一個多層的結(jié)構(gòu)。其次,在數(shù)據(jù)傳輸?shù)倪^程中加入了隨機(jī)線性網(wǎng)絡(luò)編碼。本文從理論和仿真的角度,分析了在數(shù)據(jù)傳輸過程使用網(wǎng)絡(luò)編碼較不使用網(wǎng)絡(luò)編碼在節(jié)約能耗上的優(yōu)勢。(2)提出了一種基于網(wǎng)絡(luò)編碼的WSN分簇路由協(xié)議。首先,在構(gòu)建簇的過程中充分考慮了通信距離對于信道質(zhì)量的影響,為了保證良好的通信質(zhì)量對簇的規(guī)模做出一定限制。其次,將網(wǎng)絡(luò)編碼應(yīng)用到簇頭的數(shù)據(jù)傳輸過程中,減少了簇頭節(jié)點(diǎn)發(fā)送數(shù)據(jù)的次數(shù)。建立了節(jié)點(diǎn)的發(fā)送功率和網(wǎng)絡(luò)總功率的函數(shù)關(guān)系,并給出了使得網(wǎng)絡(luò)總功率最小的最優(yōu)節(jié)點(diǎn)發(fā)送功率。最后通過仿真證明了了該協(xié)議在節(jié)約能耗上的優(yōu)勢,并且對影響該協(xié)議性能的幾個因素進(jìn)行了驗(yàn)證。
[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.
