Abstract

Development of network technology progress toward diversification, flattened and all-IP direction. Service quality assurance support mobility management in heterogeneous networks and heterogeneous network structure in the network environment, the growing number of wireless access technologies, is one of the key technologies in mobile communication system. Next-generation signaling to NSIS technologies, to address the network communication, routing information and quality of service, network security and application requirements through its own hierarchy, hierarchical processing, to provide a reliable end-to-end quality of service support network. Starting from the existing support QoS protocol, a brief introduction to the existing QoS techniques and comparative analysis of the existing QoS techniques, including IntServ, DiffServ, RSVP, and NSIS and summarized in mobility and end-to-end QoS The NSIS superiority. NS2 simulation platform thesis simulation of existing NSIS protocol network, to improve the structure of the links and nodes, connectivity verification of the NSIS wired environment and multi-hop extension, as well as the address of the application to the wireless mobile scene conversion discovery and cross-node simulation extension of the judgment, and protocol connectivity and protocol performance results. The paper analyzes the pros and cons of the existing program, the the NSIS and hierarchical mobile IP fast switching solution, the combination FHMN. The program to quickly switch trigger as reserved, advance startup upper NSIS protocol, found the judgment as well as through the the NTLP layer routing state of the NSIS NSLP layer the QoS NSLP mechanisms, prior to the completion of the handover resource reservation. The program has the introduction of the CRN judgment to reduce the overlapping path on the repeat reserved. Overhead, delay and resources of FHMIP and the NSIS protocol independent program and FHMN program occupancy simulation results proved the proposed FHMN Although some protocol overhead, but greatly reducing the processing delay will increase the network structure complex cases can significantly improve the quality of service. After the NSIS with IEEE802.21 (MIH), combined with idea, the use of the service model MIH many services with the independence of the media event triggered the upper NSIS MIH with the NSIS NSIS command issued heterogeneous media independent command service network integration programs; for NSIS routing, path, QoS assurance information to achieve a single node in the heterogeneous environment vertical QoS guarantee. Finally, the full text of the summary of the NSIS FHMIP agreement under MAP domain switching between Prospect ideas and expand NSIS recommended for the MIH up interface. In short, the text NSIS on the NS-2 network simulator to move the scene extensions proposed binding mechanism - MAP the domain FHMN program NSIS technology with existing fast switching hierarchical mobile IP technology, and given the combined with MIH heterogeneous model. The research work also had to make given the outlook of late.
