【摘要】 未来的通信网络将融合、协同多种异构网络。IETF提出的移动IP(MIP)能够将各种网络统一到单一的IP信息平台。本文重点分析了影响MIP切换时延的移动检测机制:LCS,ECS。提出了异构重叠网络下跨层优化快速检测机制。理论分析和仿真均表明由于得到了来自链路层信息的辅助,该方法能有效地降低切换时延,减少丢包,提高通信服务质量。更多还原

【Abstract】 Future network is characterized by the integration of heterogeneous wireless access technologies.The IETF Mobile IP(MIP) integrates these different networks into a single IP-based platform.This paper focuses on the analysis of movement detection mechanisms for MIP: LCS,ECS.A cross-layer fast detection method in heterogeneous overlay networks is proposed.Analysis and simulation show that with the information of link layer,the proposed scheme can achieve better performance in terms of handoff latency and packet loss.更多还原
