Proposal of a packet-lossless handover in Mobile PPC

On the mobile computing environment where countless mobile terminals are connected to the Internet for communications, it is strongly demanded that communication is maintained even when mobile terminals change their locations. However, in TCP/IP, IP addresses change along with the movement of terminals, and communication is inevitably broken. To solve this problem, we have been studying a new technology called "mobile PPC" that can achieve "mobility" only with end terminals. Although mobile PPC has resolved the problem, packet loss is unavoidable when the terminal moves. Moreover, when two end terminals move simultaneously during the communication, the communication breaks in mobile PPC. In this paper, we propose a new technology to realize a packet-lossless handover in mobile PPC taking measures both in a link layer and the function of mobile PPC in end terminals
