Abstract:
Researchers are directing enormous efforts to achieve the aim of global mobility by enhancing the standard mobile IP with various routing schemes focusing on best routes and least cost while ignoring the facts of the organizations usual use of private IP’s and the presence of firewalls. Nevertheless, existing Mobile IP models are still missing three basic concepts that hinder their applicability in real environment. First, global mobility must be independent of the different infrastructure technologies (e.g., Wi-Fi, WiMAX, UMTS, etc.). Second, a secure authentication mechanism for guiding the access of mobile nodes to the corporate network’s resources is certainly needed. Third, the capability of correlating the mobile node’s activities to a real world identity is a requirement of security in a wider since i.e., network, web, and national security. This paper defines the role of global mobility in facilitating and improving mobile business performance. It, also, presents a review of literature for the existing standards and schemes of mobility and analyzes their limitations. Finally, a reference is made to a practical approach for secure global mobility without the current limitations.
