Mobile IP based mobility management for 3G wireless networks

We present an implementation of Mobile IP (named WASMIP) in Linux. WASMIP is based on Linux OS because of the fact that it is an open source OS and provides the programmers with a great deal of flexibility when it comes to system programming. The implementation has a total of three software entities by the names of Mobile Node (MN), Home Agent (HA) and Foreign Agent (FA). These three entities are independent of each other and run as separate processes. All these entities are configurable through an Xwindows based configuration CUI. The implementation fully conforms to RFC 2002 \´SHOULD\´ requirements and supports IPin-IP encapsulation, FA care-of-address, keyed-MDS "prefix + suffix" mode of authentication and IEEE 802.1 1 wireless interfaces. Additionally. in this paper we also look at what the future has in store for Mobile IP in the light of 3G wireless networks.
