【摘要】：物聯(lián)網(wǎng)的應用和研究越來越廣泛,包含有EPC電子標簽、物聯(lián)網(wǎng)軟件、電子商務、物聯(lián)網(wǎng)體系結(jié)構(gòu)等方面。物聯(lián)網(wǎng)的目標就是要形成一個全球范圍內(nèi)的網(wǎng)絡,即如何在企業(yè)間搭建內(nèi)部的物聯(lián)網(wǎng)系統(tǒng)和各個企業(yè)之間的系統(tǒng)進行信息交互。在物聯(lián)網(wǎng)體系中,產(chǎn)品在供應鏈中進行移動和流通時,它的信息會存儲在經(jīng)過的每一個公司的EPCIS服務器中,但是儲存信息的這些公司的EPCIS服務器之間并沒有直接的聯(lián)系,要想從這些眾多的EPCIS服務器中找到出某個物品的全部信息,那么這就需要使用物聯(lián)網(wǎng)技術(shù)中的發(fā)現(xiàn)服務來進行信息查找。 發(fā)現(xiàn)服務類似Web的搜索引擎一樣,對物品進行查詢從而得到存儲物品的相關信息的EPCIS服務器的地址進而得到更詳細的信息。雖然各國都在研究物聯(lián)網(wǎng)技術(shù),但是發(fā)現(xiàn)服務還沒有形成一個標準。由于EPCglobal提出的物聯(lián)網(wǎng)的技術(shù)相對比較完善并且影響力也比較大,所以本文首先對EPCglobal提出的物聯(lián)網(wǎng)的相關技術(shù)進行了介紹,然后詳細地分析了BRIDGE項目提出的發(fā)現(xiàn)服務,并指出集中式的發(fā)現(xiàn)服務存在根服務查詢瓶頸以及安全隱私等問題。然后根據(jù)分布式網(wǎng)絡的特點,并借鑒BRIDGE項目提出的請求傳播模式的發(fā)現(xiàn)服務,提出了一種分布式的物聯(lián)網(wǎng)發(fā)現(xiàn)服務,然后對本文提出的發(fā)現(xiàn)服務在數(shù)據(jù)存儲格式、查找過程以及數(shù)據(jù)隱私安全性方面做出了詳細地分析。最后對集中式發(fā)現(xiàn)服務和本文提出的分布式發(fā)現(xiàn)服務進行了分析,首先分析了各個階段的信息查詢的時間,并進行了比較分析。然后又通過程序測試對提出的發(fā)現(xiàn)服務進行了分析,證明了能夠有效地提高網(wǎng)絡容量的利用率,解決了負載不平衡等問題。
[Abstract]:The application and research of Internet of things are more and more extensive, including EPC tag, Internet of things software, electronic commerce, Internet of things architecture and so on. The goal of the Internet of things is to form a global network, that is, how to build an internal system of the Internet of things among enterprises and how to exchange information between the systems of each enterprise. In the Internet of things system, when a product moves and flows through the supply chain, its information is stored in the EPCIS servers of each passing company, but there is no direct connection between the EPCIS servers of those companies that store the information. In order to find all the information of an item from these numerous EPCIS servers, it is necessary to use the discovery service in the Internet of things to find the information. The discovery service is similar to the Web search engine, which queries the items to get the address of the EPCIS server that stores the information about the items, and then gets more detailed information. Although countries are studying the Internet of things technology, the discovery of services has not yet formed a standard. Because the technology of Internet of things put forward by EPCglobal is relatively perfect and has great influence, this paper firstly introduces the related technology of Internet of things proposed by EPCglobal, and then analyzes the discovery service of BRIDGE project in detail. It is pointed out that the root service query bottleneck and security privacy exist in the centralized discovery service. Then according to the characteristics of distributed network and the discovery service of request propagation mode proposed by BRIDGE project, a distributed Internet of things discovery service is proposed, and then the discovery service in data storage format is proposed in this paper. The search process and data privacy security are analyzed in detail. Finally, the centralized discovery service and the distributed discovery service proposed in this paper are analyzed. Firstly, the information query time of each stage is analyzed and compared. Then the discovery service is analyzed by program test, which proves that it can effectively improve the utilization of network capacity and solve the problem of load imbalance.
