Abstract: 

This paper describes the architecture and implementa-tion of a mobile IP system. It allows mobile hosts to roam between cells implemented with 2-Mbps radio base stations, while maintaining Internet connectivity. The system is being developed as part of a course on wireless networks at Harvard and has been opera-tional since March 1994.

The architecture scales well, both geographi-cally and in the number of mobile hosts supported. It supports secure short-cut routing to mobile hosts using the existing Internet routing system without change. The implementation demonstrates a robust, low complexity realization of the architecture, and provides trade-off opportunities between efficiency and cost.

Measured performance of the mobile system is generally excellent. The system can handle a high rate of location updates, and routes packets almost as efficiently for mobile hosts as the Internet does for stationary hosts. We observe reasonable TCP behavior during hand-offs.
