【摘要】 在移动IP中,根据子网前缀以及均匀分布于区间[min,max]上的广告间隙,移动节点检测它自身是否移动.因此,区间的长度对于移动检测延时有直接的影响.然而,在移动IP 中,区间的静态配置既不方便也不灵活.根据链路带宽的利用率,提出了一种动态调整区间的新方法,并且进行了理论分析.结果显示,与静态区间相比,动态区间的方法显著地减少了不必要的移动检测延时.更多还原

【Abstract】 In Mobile IP, MN detects its movement according to subnet prefix and router advertisement interval which forms a uniform distribution in the region [min,max]. Therefore, the size of this region has a direct impact on movement detection delay. However, this region is configured statically in Mobile IP, which is inconvenient and inflexible. In this paper, this region is adjusted by using the link bandwidth, and a movement detection delay formula is given. In addition, the proposed method is modeled and analyzed. All the results show that the dynamic region, compared with the fixed region, could reduce the unnecessary movement detection delay drastically.更多还原
