In order to complement this defect, an enhanced version for the middle-domain mobility management is designed in this paper.
The proposed dynamic handoff mechanism for mobility management is designed to minimize the handoff latency in IEEE 802.11 wireless local area networks, which in turn reduces the data loss and the signalling overhead in real-time applications.
Moreover, mobility management protocols are designed for specific needs, for example, the purpose of IPv6-based mobility schemes consists of managing users roaming while ignoring access network discovery.
The inherent characteristics of WMNs, such as relatively static backbones and highly mobile clients, require new mobility management solutions to be designed and implemented.
It is also obvious that mobility management and admission control design for the mmWave-based dense HetNet deserve much more research before one can indeed bring potential benefits of mmWave communications to practice.
Thus, researchers have been motivated to continuously design new mobility management protocols suitable for sensor group mobility.
The emphasis of this paper is on investigating the performance of signalling protocols designed for a mobility management scheme, which uses Mobile IP for inter-segment mobility in a hybrid space and terrestrial environment.
The Proxy Mobile IPv6 (PMisv6) is designed to provide network-based mobility management support to a mobile node (MN) without any involvement of the MN in mobility related signaling; hence, the proxy mobility entity performs all related signaling on behalf of the MN.
Hence, Designing proficient mobility management to seamlessly integrate heterogeneous wireless networks with all-IP is the most challenging issue in 4G networks.
