Performance comparison of hinted- and advertisement-based movement detection methods for mobile IP hand-offs

摘要

In this study hinted cell switching (HCS) is introduced as a new alternative to the mobile internet protocol (MIP) advertisement-based movement detection methods. It is a method that relies on “hints” generated during subnetwork layer hand-offs for reacting faster to MIP hand-offs. In this study the performance of HCS is com- pared through the use of simulations against those of advertisement-based movement detection methods, namely, lazy cell switching (LCS) and eager cell switching (ECS). The performance of the latter is determined for a range of advertisement periods. The scenarios investigated involve straight line movement patterns and MIP hand-offs between foreign agents. It is shown that HCS significantly outperforms its advertisement-based counterparts in managing faster movement detection, performing independently of agent advertisement period lengths and pro- viding a small deviation to its performance. Overall, it is demonstrated through simulations of Internet audio streaming that MIP hand-offs with HCS support complete faster with minimum packet loss. Finally, it is identified that ECS performs significantly faster than LCS in the investigated scenario.
