In order to get the best routing from the correspondent node to the mobile node , which passes the mobile node ' s home agent , the proposed method has been improved by a series of experiments . thus , the scheme is to be proved useful steeply in this essay 本文的第五章提出了适合基于wlan的移动ip大流量移动节点在定向运动下的网络模型,并分析了该模型的移动ip性能,获得了丢包数与网络延时和移动节点速度之间的关系。
When the temperature t is larger , the particles can span the potential at the effect of the average force , so the ratio of them is near linear relevant . besides , the interaction between particles is not considered . this interaction also has an effect on the current 在低温时,虽然斜率大,但由于温度相对势垒较低,马达难以跨越势垒,从而定向运动的几率流较小,几率流与有效势倾斜的比值(随温度的变化)也就不会是简单的线性相关。
The focus of our study is concentrated on a two - state model , in which we choose ( m , k ) = ( 2 , 2 ) and calculate the average current as a function of the transition width , temperature and transition rates . the results are summarized as follows : for small temperature , as well as for very high temperature the current vanishes 计算结果表明,在温度很低或很高时,定向运动的几率流都趋于零;在适当的温度范围内,对于某一确定的跃迁速率,总存在一个几率流的最大值,而且随着速率的增加相应于最大几率流的温度值升高。
