摘要

In this paper cost analysis of a three-layer hierarchical model and HMIPv6 is done. The objective of this work is to examine the signaling cost, tunneling cost and packet dropping probability at top level anchor agents of a Multi-level (3 levels) architecture and HMIPv6 and to observe in what scenario multiple levels of hierarchy can give better performance over HMIPv6. Analysis of both the models revels that neither of the model is suitable for all scenarios. There are certain scenarios where the three layer architecture is suitable than HMIPv6. When both the speed and density of mobile node is high, large BU signal is generated and traverse the entire local network in HMIPv6. But due to the presence of intermediate anchor agents these signal overloads only a portion of the local network. So, in such situations TLMIPv6 outperforms HMIPv6. In the first part of the paper, above mentioned parameters are evaluated mathematically and then they are verified by ns-2 simulation. A comparative analysis is presented at the end of the paper to provide an insight under what scenarios three layer model perform well.
