Heterogeneous networks have attracted a lot of interest due to its support provision for a large number of networks at an effective cost. Mobility Management also plays an important role in the heterogeneous network in providing a seamless mobility support for both devices and users, which poses a serious challenge. In this chapter, the researchers propose SIP-PMIP Cross-Layer Mobility Management in order to provide a seamless mobility in heterogeneous wireless networks. In effect, the researchers design a Cross-Layer Mobility Management Scheme, which can handle terminal, network, personal and session mobility. To demonstrate, video conferencing is included in the modeling, simulation and implementation of the module using Riverbed Modeler.
The rapid evolution of the communication technology started with the diffusion of information between connected computers to the present system in which voice, video, etc. are being exchange between systems. Driven by the global educational challenge in the twenty-first century, the Nigerian University Commission had stated that Nigerian university system will now go paperless as it has launched a portal called NUSMAP. The major set-back to the realization of the objectives of NUSMAP is that most Nigerian universities still handle their information system manually by using paper as a delivery vehicle. Some use the single management system. Other universities employ the LAN management model, where each department and/or unit has its own established management information system on the LAN. Very few universities use a campus network where departments/units can share information. In view of the above, the researchers propose a campus network that will be a modelled management information system for information diffusion and management in Nigerian universities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
