In the operation of hierarchical mobile IPv6 (HMIP) (H. Soliman, et al., 2003), a mobile node (MN) is supposed to send binding updates (BUs) to the home agent (HA) and a mobility anchor point (MAP); therefore, a MAP discovery protocol is needed to fa

Mobile IPv6 cannot achieve seamless handoff for both UDP communications such as voice over IP (VoIP) and TCP communications such as FTP, since bursty packet loss during handoff degrades their transmission quality. In order to present completely burst

Mobility support for mobile networks will be more important as the mobile Internet becomes increasingly popular. To support mobile networks, the concept of prefix scope binding (PSB) is being discussed in IETF; however, by only applying this concept

In Japan, a circuit-switched voice and data communication service has been provided as the PDC (Personal Digital Cellular) system. Especially in the data communication service, a 9.6 kbps transmission rate service is now offered. Moreover, to meet th

Mobile IPv6 supports packet routing for hosts moving on the Internet, but lacks support for networks moving on the Internet. For example, a network comprising a set of hosts and routers in a train can be a mobile network. While the mobile network is

Gene amplification is a particular feature of certain human tumors. Epidermal growth factor receptor (EGFR) [1], c-erbB2 [2], N-myc [3], and c-myc [4] are cellular oncogenes that show gene amplification of human tumor tissues of glial origin. The fre
