With the advent of various access technologies and increasing number of applications, a set of challenges concerning efficient delivery of ubiquitous services to heterogeneous users and devices have been posed. One of the important challenges is to integrate quality of service (QoS), security and mobility support in heterogeneous networks. To facilitate the interworking of these mechanisms we propose...
Delivering ubiquitous services to various users and devices through heterogeneous networks is a major aim in next generation networks. The delivery should be efficient and secure. The support and integration of security, quality of service (QoS) and mobility management (MM) in access networks become parts of the essential issues. An enhanced node (EN) with a network sub-layer is proposed here to achieve...
