【摘要】：物理世界的聯(lián)網(wǎng)需求和信息世界的擴(kuò)展需求催生出了一種新類(lèi)型的網(wǎng)絡(luò)—物聯(lián)網(wǎng)。物聯(lián)網(wǎng)是一個(gè)以互聯(lián)網(wǎng)、傳統(tǒng)電信網(wǎng)等為信息載體,通過(guò)RFID、無(wú)線(xiàn)傳感器等各種信息傳感設(shè)備,讓普通物理對(duì)象能夠被獨(dú)立尋址,從而實(shí)現(xiàn)互聯(lián)互通功能的網(wǎng)絡(luò)。隨著物聯(lián)網(wǎng)產(chǎn)業(yè)發(fā)展迅速,無(wú)線(xiàn)傳感器網(wǎng)絡(luò)作為物聯(lián)網(wǎng)感知層的重要支撐技術(shù)成為物聯(lián)網(wǎng)技術(shù)研究的重點(diǎn)領(lǐng)域。 無(wú)線(xiàn)傳感器網(wǎng)絡(luò)(Wireless Sensor Network, WSN)將大量傳感器節(jié)點(diǎn)布置到需要監(jiān)控的區(qū)域,通過(guò)其自身的自組網(wǎng)能力收集物理世界的數(shù)據(jù)和信息,而路由協(xié)議是數(shù)據(jù)傳輸?shù)幕A(chǔ),因此,路由協(xié)議是確保WSN高效通信的關(guān)鍵協(xié)議之一。由于無(wú)線(xiàn)傳感器網(wǎng)絡(luò)中的節(jié)點(diǎn)資源有限,并且一般不能補(bǔ)充能量,設(shè)計(jì)性能高效的無(wú)線(xiàn)傳感器網(wǎng)絡(luò)路由協(xié)議具有十分重要的意義,所以本論文圍繞WSN路由協(xié)議展開(kāi)研究工作。 本文通過(guò)對(duì)國(guó)內(nèi)外研究學(xué)者和機(jī)構(gòu)提出的各種無(wú)線(xiàn)傳感器網(wǎng)絡(luò)路由協(xié)議學(xué)習(xí)與研究基礎(chǔ)上,重視理論和實(shí)踐相結(jié)合,選擇已在實(shí)際應(yīng)用部署的無(wú)線(xiàn)傳感網(wǎng)絡(luò)系統(tǒng)廣泛使用,基于TinyOS系統(tǒng)平臺(tái)下的CTP路由協(xié)議進(jìn)行研究。本文在分析CTP協(xié)議原理的基礎(chǔ)上,指出了CTP協(xié)議存在負(fù)載不均衡的問(wèn)題,影響網(wǎng)絡(luò)的能量消耗和生存時(shí)間,并針對(duì)以上問(wèn)題設(shè)計(jì)了負(fù)載均衡的無(wú)線(xiàn)傳感網(wǎng)絡(luò)V-CTP路由協(xié)議。V-CTP協(xié)議選擇鏈路指標(biāo)時(shí),考慮節(jié)點(diǎn)所攜帶子節(jié)點(diǎn)的個(gè)數(shù)和次優(yōu)路徑進(jìn)行數(shù)據(jù)轉(zhuǎn)發(fā),設(shè)計(jì)了虛擬鏈路指標(biāo)v-eetx,并用這一指標(biāo)進(jìn)行路由選擇。本文在保留CTP協(xié)議好的機(jī)制解決其不足的基礎(chǔ)上,設(shè)計(jì)并在TinyOS平臺(tái)下實(shí)現(xiàn)了V-CTP協(xié)議。最后,本文通過(guò)在實(shí)際的節(jié)點(diǎn)平臺(tái)上進(jìn)行大量實(shí)驗(yàn),對(duì)V-CTP和CTP協(xié)議進(jìn)行性能比較,實(shí)驗(yàn)結(jié)果表明,V-CTP協(xié)議在保證數(shù)據(jù)傳輸可靠性的前提下,彌補(bǔ)了CTP協(xié)議的不足,實(shí)現(xiàn)了負(fù)載均衡,降低了網(wǎng)絡(luò)能量的消耗,延長(zhǎng)了網(wǎng)絡(luò)生存時(shí)間。
[Abstract]:The need for networking in the physical world and the expansion of the information world have given birth to a new type of network-the Internet of things.The Internet of things (IoT) is a network with Internet, traditional telecommunication network as information carrier, through RFID, wireless sensor and other information sensing equipment, ordinary physical objects can be independently addressed, so as to achieve the function of interconnection.With the rapid development of the Internet of things (IoT) industry, wireless sensor networks (WSN), as an important supporting technology of the IOT perception layer, has become the key area of the research of IOT technology.Wireless Sensor Network (WSNs) arranges a large number of sensor nodes to the area to be monitored, collects data and information from the physical world through its own self-organizing network capability, and the routing protocol is the basis of data transmission, so,Routing protocol is one of the key protocols to ensure the efficient communication of WSN.Due to the limited resource of nodes in wireless sensor networks and the lack of energy, it is very important to design efficient routing protocols for wireless sensor networks. Therefore, this paper focuses on the research of WSN routing protocols.On the basis of studying and researching various routing protocols of wireless sensor networks put forward by domestic and foreign researchers and institutions, this paper attaches importance to the combination of theory and practice, and selects the wireless sensor network systems which have been deployed in practice and are widely used.Research on CTP routing protocol based on TinyOS system platform.Based on the analysis of the principle of CTP protocol, this paper points out that the CTP protocol has the problem of load imbalance, which affects the energy consumption and lifetime of the network.Aiming at the above problems, a load-balanced V-CTP routing protocol. V-CTP protocol is designed to select the link index, considering the number of sub-nodes carried by the node and the sub-optimal path for data forwarding.A virtual link index v-eetx is designed and used for routing.On the basis of preserving the good mechanism of CTP protocol to solve its shortcomings, this paper designs and implements V-CTP protocol on TinyOS platform.Finally, through a large number of experiments on the actual node platform, this paper compares the performance of V-CTP and CTP protocol. The experimental results show that the V-CTP protocol makes up for the deficiency of CTP protocol on the premise of ensuring the reliability of data transmission.The load balance is realized, the network energy consumption is reduced, and the network lifetime is prolonged.
