....load grows rapidly. Network support for seamless mobility was not a primary design consideration when Mobile IP was first defined in the early 90s. More recently the Mobile IP Working Group has been addressing this issue. In the case of frequent handoff, micromobility protocols have been proposed [2,10,11,14] to handle local movement of mobile hosts without interaction with the Mobile IP enabled Internet. This has the benefit of reducing delay and packet loss during handoff and eliminating registration between mobile hosts and distant home agents when mobile hosts remain inside their local coverage ....

....results from an implementation of Cellular IP in an experimental wireless testbed. We analyze the performance of Cellular IP in support of UDP and TCP applications. Section 5 presents a detailed quantitative comparison of Cellular IP and other micromobility protocols discussed in the literature [10,11]. Finally, in Section 6, we present some concluding remarks. 2. Related work A number of micromobility solutions have been discussed in the literature. In [14] a hierarchical mobility model is described where independent wireless access networks interwork with a global mobility protocol. Address ....

....connect to the Internet via base stations and change their point of access frequently. A change of access point during active data transmission or reception is called a handoff. During or immediately after a handoff, packet losses may occur due to delayed propagation of location update information[7, 8]. These losses should be minimized in order to avoid a degradation of service quality as handoff become more frequent. To solve this problem we must design a protocol that provides mobility and handoff support for mobile hosts that change base stations frequently. We will study methods of local ....

To coordinate these two daemons, a route manager is used to control the system s routing table. Compared to [21] [17], our network architecture does not rely on hierarchical (wireline) routers. Instead, following the basic idea of ad hoc networks, mobile hosts are used as routers to extend the coverage of FAs. Thus, our framework also support micro mobility as well as macro mobility.

In this case the new base station notifies the old base station of the pending handoff.
