Mobile Ip Switch Optimization Studies

While more and more Wireless network obtains widespread application, each kind wireless turned on technical development enable the based on the IPv4 Internet system structure to have the profound transformation, massive wireless terminal deviceturning on, on the one hand, it further intensified the difficult position which the IPv4 address resources dried up; On the other hand, it request the IP network more reliable. But on wireless data network, mobile IP is not actual use truely until now, the main reason is that when mobile IP from the start to carries out and last to complete the entire process can spend a more serious correspondence time delay, this kind of correspondence time delay greatly restricted the mobileIP's practical advancement. Study the wireless turn on the Internet's basic theory and the core essential technology has the significant scientific value and the economic value.This article first introduced the wireless network technology and next show the correlation mobile IP technology, level cut, fast cut and smooth cut plan, analysis the plan which carried on,we drawn out this optimized plan: think about the triggers cut and the protocol analysis based on the link level, proposed the double link triggers cut plan. In the paper's final chapter it introduced each kind of simulation software, chose OPNET simulation software after the analysis and comparison to carry on the simulation confirm the plan, theoretical analysis and the simulationresult indicated, this cut optimization plan realization simple, reliable,comparing traditional method, this plan has a lot improvement.
