—Rapid advances in wireless networking have led to more mobile phones, PDAs, and other digital mobile devices becoming ubiquitously connected to the Internet. As the demand of delay sensitive real-time applications for these portable devices increases, providing seamless connectivity to wireless networks becomes a critical issue. For this reason, a number of micro-mobility protocols, such as Cellular IP, have been proposed to complement the Mobile IP protocol. However, providing fast and reliable handoff is still a major obstacle to enabling seamless micro-mobility in wireless access networks. Cellular IP semi-soft handoff has been proposed to address such challenge. Evaluations have been performed which show that semi-soft handoff yields better performance than the conventional hard handoff. However, these studies are based on symmetrical network topologies and loads. In practice, network topology varies and the network load fluctuates depending on numerous parameters (e.g., number ...
