【摘要】：物理世界的聯(lián)網需求和信息世界的擴展需求催生出了一種新類型的網絡—物聯(lián)網。物聯(lián)網是一個以互聯(lián)網、傳統(tǒng)電信網等為信息載體,通過RFID、無線傳感器等各種信息傳感設備,讓普通物理對象能夠被獨立尋址,從而實現(xiàn)互聯(lián)互通功能的網絡。隨著物聯(lián)網產業(yè)發(fā)展迅速,無線傳感器網絡作為物聯(lián)網感知層的重要支撐技術成為物聯(lián)網技術研究的重點領域。 無線傳感器網絡(Wireless Sensor Network, WSN)將大量傳感器節(jié)點布置到需要監(jiān)控的區(qū)域,通過其自身的自組網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,因此,路由協(xié)議是確保WSN高效通信的關鍵協(xié)議之一。由于無線傳感器網絡中的節(jié)點資源有限,并且一般不能補充能量,設計性能高效的無線傳感器網絡路由協(xié)議具有十分重要的意義,所以本論文圍繞WSN路由協(xié)議展開研究工作。 本文通過對國內外研究學者和機構提出的各種無線傳感器網絡路由協(xié)議學習與研究基礎上,重視理論和實踐相結合,選擇已在實際應用部署的無線傳感網絡系統(tǒng)廣泛使用,基于TinyOS系統(tǒng)平臺下的CTP路由協(xié)議進行研究。本文在分析CTP協(xié)議原理的基礎上,指出了CTP協(xié)議存在負載不均衡的問題,影響網絡的能量消耗和生存時間,并針對以上問題設計了負載均衡的無線傳感網絡V-CTP路由協(xié)議。V-CTP協(xié)議選擇鏈路指標時,考慮節(jié)點所攜帶子節(jié)點的個數(shù)和次優(yōu)路徑進行數(shù)據(jù)轉發(fā),設計了虛擬鏈路指標v-eetx,并用這一指標進行路由選擇。本文在保留CTP協(xié)議好的機制解決其不足的基礎上,設計并在TinyOS平臺下實現(xiàn)了V-CTP協(xié)議。最后,本文通過在實際的節(jié)點平臺上進行大量實驗,對V-CTP和CTP協(xié)議進行性能比較,實驗結果表明,V-CTP協(xié)議在保證數(shù)據(jù)傳輸可靠性的前提下,彌補了CTP協(xié)議的不足,實現(xiàn)了負載均衡,降低了網絡能量的消耗,延長了網絡生存時間。
[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.
