The steady improvements in the networking infrastructure and ever increasing broadband penetration has fueled the resurgence of voice-over-IP (VoIP). One of the important contributors to this growth has also been the development and wide acceptance of the session initiation protocol (SIP). However, the current usage of SIP requires a per-application deployment (each application using its own SI...

EXTENDED ABSTRACT Mobility, from the perspective of a network, is the ability to change network points of attachment. Support for mobility can be provided at the link layer (e.g. cell phones, 802.11) or at the network layer (e.g. Mobile IP). Link layer solutions are limited to point-to-point connectivity choices between the mobile and a base station. Network layer solutions are limited to infor...

Due to the ubiquitous explosion of the Internet and the fast proliferation of heterogeneous networked devices and services, the end user are faced with a formidable task in managing it all. The Device Unifying Service presented in this paper is a novel powerful concept that allows anyone confronted with multiple devices and services to administer and manage them by themselves. With this service...

Mobility management with provision of seamless handover is crucial for an efficient support of global roaming of mobile nodes (MNs) in next-generation wireless networks (NGWN). Mobile IPv6 (MIPv6) and its extensions were proposed by IETF for IP layer mobility management. Mobile IPv6 developed in 1997 is considered to be one of the key technologies for realizing mobile Internet which enables sea...
