Design Of IPv6 Address Auto-configuration For RFID-sensor Network

As an important part of the Internet of Things sensing layer,RFID networks and wireless sensor networks have been applied in many fields of our life.The fusion of the two technologies into RFID network has attracted more and more researchers' attention.With the continuous progress of technology,the number of terminal devices is increasing,the address pool of IPv4 has become increasingly scarce,and it is difficult to meet the huge demand for network addresses of the Internet of Things sensing layer.This paper focuses on the integration of the Internet of Things sensing layer and the next generation Internet IPv6.Focus on the new field of RFID sensor networks and the automatic configuration of IPv6 addresses of these nodes.The main research work is as follows:(1)Research on Radio Frequency Identification Sensor Network.Analyze and compare the existing RFID network architecture,and propose a network architecture of a radio frequency identification sensor network that supports IPv6 communication in a large number of rapid deployments.Mainly through the transformation of the node,the sensor node can communicate directly with the reader node,which solves the problem of large structural interference and hardware waste.The wireless self-organizing method enables the node to be deployed quickly and in large quantities.(2)Research on IPv6 Address Automatic Configuration Algorithms.Design a set of IPv6 address automatic configuration scheme for the network architecture of the RFID sensor network proposed in this paper.This paper analyzes the structural characteristics of the network architecture clustering multi-hop proposed in this paper.Combined with the IPv6 address format and the existing wireless sensor network address auto-configuration protocol,this paper redefines the IPv6 address format and designs the related data packets.The automatic configuration process of the IPv6 address of the new node,the algorithm combines the top-down broadcast mechanism of the proxy node and the bottom-up address configuration request mechanism of the new node,avoiding the problem that the new node waits too long or the packet floods The node's IPv6 address is layered by the corresponding proxy node for stateful address allocation.The node address conflict detection link is used to reduce the address configuration energy consumption,and multiple nodes perform address configuration to improve the efficiency of address allocation.Finally,the special situation handling mechanism such as failure and fault movement of the node may be discussed.(3)In the simulation environment of OPNET Modeler 15.4,the IPv6 address configuration scheme and Strong DAD proposed in this paper are simulated.The simulation results show the feasibility and superiority of the scheme.
