There are many obstacles exit in the mobile management scheme, it mainly shows in its not high switching performance, excess signaling overhead and too long handoff delay, hard guaranteed quality of service in handoff as well as safety problem. It put forwards a fast handoff scheme which advances HMIPv6 by giving it authority to temporary mobility anchor point (LT-TMAP). The lower level access router is licensed through upper level of MAP, make it a temporal mobility anchor point to give distribute management to mobile node, and describe the implementation process theoretically. In the end, we use the NS-2 simulation tool to build network topology and based on the IPv6 test-bed build in our school network laboratory which I help researched to give a simulation test to that handoff scheme. It proves the handoff scheme can take better advantage of the network MAP resource, has stronger real-time performance, and higher handoff efficiency.

In order to solve the security issue about network intrusion in IPv6 system, two modes of intrusion detection system based on IPv6 protocol analysis have been developed and designed. Based on these two modes, packet capture module, protocol analysis module, command parsing module and out-put processing module have been designed. The accuracy and efficiency of intrusion detection system based on IPv6 protocol analysis have been verified through the test focused on the key modules.

multilevel security technology has broad applications in military and commercial aspects, the key technology in the research of multilevel security network, based on the BLP model of a security enhancement model is presented, and proved its security of the model. Secondly, based on the analysis of RBAC96 model cluster, proposes a licensing scheme of multilevel mobile IPv6 network based on role. Again gives an implementation scheme of multilevel security network in mobileIPv6 network environment. Including the configuration and deployment of mobile IPv6 environment of multilevel security network, and gives the process of multilevel security network. Finally, the simulation results of multilevel security network is given. The results show that, the multilevel security network design to meet the functional requirements of multilevel security network.

Based on ISO/IEC 18000-6 Type B protocol, 915MHz RFID reader has been designed. FPGA is used to process the digital signal that is based on the protocol and C8051F020 is used as the controller. Each module in FPGA and verification module is designed by Verilog HDL. They are synthesized by Quartus II with EP1C6Q240C8 CMOS chip of the Altera as the target device, and they are verified on both timing and function. The result shows that it could satisfy the technology index of ISO/IEC18000-6 Type B requests and possess the advantages of flexible structure, small size and easily upgrading, etc.
