蜂窝重叠情况下移动IP切换延时分析

Model and analysis of handoff delay for mobile IP in the case of cell overlap

从理论上首次对移动 IP 切换过程中的切换延时和乱序分组进行了建模和分析,分别得到了各自的概率分布公式。并且根据这个结果,优化了重叠区域的半径。结果表明:本模型准确地描述了移动 IP 的切换行为,它对于评价移动 IP 的切换性能非常有用。

The handoff delay and out-of-sequence packets in the handoff process of Mobile IP were numerically analyzed for the first time, and the general expressions of their probabilities were obtained respectively. And according to the results, the radius of overlap region was optimized. The illustrations show that the proposed method models precisely the handoff characteristic. The probabilities are very helpful to evaluate handoff performance.
