【摘要】：隨著低功耗無線通信技術(shù)、傳感器技術(shù)、微機(jī)電技術(shù)以及嵌入式系統(tǒng)技術(shù)的迅速發(fā)展，無線傳感器網(wǎng)絡(luò)技術(shù)也取得了巨大發(fā)展。作為一種新興的信息獲取技術(shù)，無線傳感器網(wǎng)絡(luò)與塑料電子學(xué)、仿生人體器官并稱為全球未來三大高科技產(chǎn)業(yè)，它在軍事、環(huán)境、生物、醫(yī)療保健、空間探索、目標(biāo)跟蹤、入侵檢測(cè)、氣候監(jiān)測(cè)、災(zāi)難救援和商業(yè)貿(mào)易等領(lǐng)域都有著極高的應(yīng)用價(jià)值。 路由協(xié)議是無線傳感器網(wǎng)絡(luò)中的一項(xiàng)關(guān)鍵技術(shù)，，由于網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的不同，傳統(tǒng)網(wǎng)絡(luò)路由協(xié)議無法適用于無線傳感器網(wǎng)絡(luò)，必須設(shè)計(jì)新的路由協(xié)議。在眾多無線傳感器網(wǎng)絡(luò)路由協(xié)議中，典型的分簇路由協(xié)議LEACH是當(dāng)前研究的重點(diǎn)。 本文首先介紹了無線傳感器網(wǎng)絡(luò)的研究現(xiàn)狀、應(yīng)用前景、基本概念和特點(diǎn)。其次簡(jiǎn)單分析了幾種典型的無線傳感器網(wǎng)絡(luò)路由協(xié)議，并著重介紹和分析了LEACH協(xié)議的工作機(jī)制和優(yōu)缺點(diǎn)。 最后，針對(duì)LEACH協(xié)議在選擇簇首時(shí)不考慮節(jié)點(diǎn)剩余能量、不考慮節(jié)點(diǎn)到匯聚節(jié)點(diǎn)的距離、簇首節(jié)點(diǎn)數(shù)占總節(jié)點(diǎn)數(shù)量百分比的期望值不變這三個(gè)缺陷，本文提出了相應(yīng)的改進(jìn)方案，并使用MATLAB對(duì)改進(jìn)后的LEACH協(xié)議進(jìn)行了仿真實(shí)驗(yàn)，并與原始LEACH協(xié)議進(jìn)行了對(duì)比。實(shí)驗(yàn)結(jié)果表明，改進(jìn)后的LEACH協(xié)議在網(wǎng)絡(luò)的能量有效性以及網(wǎng)絡(luò)吞吐量性能上都有所提高，而且改進(jìn)后的LEACH協(xié)議相比于原始LEACH協(xié)議更加適用于大規(guī)模無線傳感器網(wǎng)絡(luò)。
[Abstract]:With the rapid development of low-power wireless communication technology, sensor technology, micro-electromechanical technology and embedded system technology, wireless sensor network technology has made great progress.As a new information acquisition technology, wireless sensor networks (WSN), plastic electronics, biomimetic human organs are known as the three future high-tech industries in the world, including military, environment, biology, health care, space exploration, target tracking.Intrusion detection, climate monitoring, disaster relief and commercial trade and other fields have high application value.Routing protocol is a key technology in wireless sensor networks. Due to the difference of network topology, traditional network routing protocols can not be applied to wireless sensor networks, so it is necessary to design new routing protocols.Among many routing protocols in wireless sensor networks, the typical clustering routing protocol (LEACH) is the focus of current research.This paper first introduces the research status, application prospects, basic concepts and characteristics of wireless sensor networks.Secondly, several typical routing protocols in wireless sensor networks are briefly analyzed, and the working mechanism, advantages and disadvantages of the LEACH protocol are emphatically introduced and analyzed.The improved LEACH protocol is simulated by MATLAB and compared with the original LEACH protocol.The experimental results show that the improved LEACH protocol improves the network energy efficiency and network throughput performance, and the improved LEACH protocol is more suitable for large-scale wireless sensor networks than the original LEACH protocol.
