Research On Access Technology Of Low Intelligent Node In The Internet Of Things Based On IPv6

With the developing of information technology, the Internet of Things, as one ofthe future trends in network development, is a focus for researchers. In terms of thepresent research, people have no unified understanding on architecture of theInternet of Things, the technical level, and communication protocols. There is a lotof work to be done on the research and application. The core of the next generationof Internet technology is IPv6. IPv6technology is very useful for the Internet ofThings in the design, therefore, on the basis of IPv6, this paper try to do someresearch on the Internet of things.Underlying the Internet of Things, there will have a large number of nodesbeing used for information gathering and intelligent control. These nodes havedistinct characteristics; structure and function are simple, low processing and storagecapacity, strong mobility, and large quantities. In this paper, they will be called aslow intelligence codes. The low intelligent nodes will be an indispensable part of thesupport for networking applications. But on the internet Of Things, low intelligentnodes must be accessed to the backbone network whose core is IPv6In terms ofpresent accessing technology, there will be a series of problems such as lowintelligence nodes address accessing issues, lack of processing capacity, it can notcompute complex data. The study of these problems can make scene on solvinglarge-scale application of the Internet of Things.IPv6as the access network in this paper works in two areas: one for lowintelligence node address configuration process when the network access problemwith an algorithm for node access of low intelligence in the Internet of Things; theother proposed a design for the lack of low intelligence node data processingcapabilities problem.IPv6technology uses stateless and states auto configuration to configure thenode address in the Internet of things, if you use states auto configuration toconfigure the node address, due to the huge number of nodes, the performance of theserver’s requirements will be high. Therefore, in the Internet of Things can only usestateless auto-configuration to the node address configuration. The need for neighbor discovery in the stateless auto-configuration, to ensure that the link-ID of the node isthe only conflict, need to wait for manual configuration; huge number ofnodes in the Internet of Things, highly mobile, so by the manual to complete theconfiguration of the node address is unrealistic, and low intelligence node due to itssmaller range of addresses, in the presence of low intelligence node conflict willgreatly increase. To solve this problem this random shift change after the discoveryof the conflict has generated address to complete the configuration of the lowintelligence node address.Due to the low processing power and storage capacity of the low-intelligentnode, the access is not like a traditional Internet node freely, in the traditionalInternet, IEEE802.15.4and6LowPan to solve the wireless personal area networknode network problems, but low intelligence in the Internet of Things nodes than inthe personal area network complexity, low intelligent node network based on IPv6toexpand some proposed use of the management server to the auxiliary dataconversion. In order to make the management server to complete its function, do thefollowing work: First, add node option of a low intelligence on the basis of IPv6extension header, extension header to distinguish between normal data packets andsent to the low intelligent node packet the definition of flag C in the extended headerto distinguish packets from the communication side or from the management server.Secondly, the increase in the routing node-server address mapping table byquerying the table to complete the forwarding of data. With these modifications toensure the communication on the side to the low intelligent node packet are firsthandled by the management server before sending to the low-intelligent nodes.Developed a node-server mapping table, maintenance update message packet,management server binding, update message packet to the server to bind tomaintenance.The final design of the NS2simulation experiments to verify the feasibility ofthe program on communication, the experimental results, and the program produceda certain effect on the original IPv6protocol, the handoff delay is a bit slight increase,but has little effect.
