Mobile Networking

through Mobile IP

MotivationThe huge market demand drives the growth of Mobile IP. Besides, the technologies of GPRS and WLAN are also boosting the development of Mobile IP. Mobile IP is the earliest solution to mobility management of IP network. The seamless usage of internet in portable devices. Solution of handoff problem.

IntroductionMobile networking is something which is capable of maintaining network connectivity even when there is a change in the point of attachment to the Internet . • Home address (HA)• Care-of address (CoA)Mobile networking doesn't has geographical limitations .

Issues of HandoffHandoff is the transition for any given user of signal transmission from one base station to a geographically adjacent base station as the user moves around. • Dropping ip packets • Handoff latency

Solution• Reducing packet loss by delivering binding update to the

mobile node’s previous foreign agent.• Smoothing handoff by defining a previous foreign agent

notification message.• Establishment of a registration key by optimizing route.

Establishment of Registration Key

• Providing a security association with its foreign agents to the mobile node.

• At the conclusion of the registration process, it allows the distribution of the registration key to both the mobile node and the foreign agent.

• Eliminating most common man-in-the-middle attacks by securely establishing a registration key.

ConclusionMobile IP is the genesis and continuing motivation for a worldwide effort to bring wireless data communications into common use.It seems certain that Mobile IP will play an increasingly important part in the deployment of future Internet mobile networking.
