Performance Evaluations of an IDMP-based Macro-mobility Management in Heterogeneous Wireless Networks

An improved Intra-domain mobility management protocol (IDMP) basedMacro-mobility management (IDMP-MM) mechanism is proposedin heterogeneous wireless networks. It adopts Layer-2 fast handofftrigger, the edge-cells controller to improve intradomain mobility, andthe pre-registration method with the aid of address-table mappingbetween mobility agents to enhance interdomain mobility. The proceduresof intradomain and interdomain handoff in IDMP-MM are describedrespectively, and the performance measurements of IDMP-MM areevaluated. The simulation results show that IDMP-MM mechanism canprovide efficient mobility management to reduce the global signalingcost, the number of buffering in-flight packets, and execute fasthandoff for ongoing calls.
