| Abstract: | 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. |
