The Internet Mobile Host Protocol (IMHP)
Charles E. Perkins, Andrew Myles, David B. Johnson · 2007
This paper describes the Internet MobileHost Protocol (IMHP), which allows transparent routing of IP packets to mobile hosts in the Internet, while using only the mobile host's home IP address. No changes are required in stationaryhosts that communicate with mobile hosts, and no changes are required in mobile hosts above the IP level. IMHP quickly converges to optimal routing following the movement of a mobile host, while maintaining the weak security model of today's Internet. Detailed examples of operation are presented. I. Introduction Within the last few years, there has been impressive growth in the number of portable computers in use. Moreover, the fact that a computer is portable no longer implies that it has limited processing power. Today's mobile computers have hundreds of megabytes of disk space, window-based user interfaces, color displays, and sophisticated devices for data communications. The combination of power and mobility promise to reshape the way we think of comput...
