In this paper, simulation approach for verification and evaluation of the proposed mobility management mechanisms is presented. The architecture of considered wireless communications system consists of three main components, i.e. core communications segment (CCS), wireless local area networks (WLANs) and network management centre (NMC). The paper is based on both Home Agent (HA) replication and user's services profile transferring to a new location is described in detail. WLAN is connected to the core communications segment by high capacity line of sight (HCLOS) radio links. Network management center performs an essential role in supporting the mobility management functions. Both COMNET and OPNET simulation packages were used for quality assessment of the modified IPv6 mobility management procedures. The simulation results presented in the paper confirmed that the modified procedures significantly improve the wireless network accessibility.
