The introduction of ATM in wireless CPN environments (WATM) necessitates the design of mobility signalling protocols, since the existing versions of BISDN signalling do not support terminal mobility. These protocols can be deployed either as extensions to the standard signalling capabilities, or as individual solutions that have little or no impact on existing infrastructures (switches, signall...

Mobile IP is a network layer solution to the wide-area mobility problem in the Internet. Mobility agents’ hierarchies and regional registrations have been introduced in the foreign domain as a local-area mobility support solution. In this paper, we critique the current regional registration proposal identifying some drawbacks with its registration mechanisms signaling design. In addition, we in...

teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...

The tremendous demands from social market are pushing the development of mobile communications faster than ever before, leading to plenty of new techniques emerging. Within those techniques, mobility management has widely been recognized as one of the most important problems for a seamless access to wireless networks and services. This paper proposes a conceptual framework for mobility and mobi...

We propose and analyze a regional registration based mobile multicast service management scheme which we call URRMoM for efficiently supporting mobile multicast in Mobile IP networks. URRMoM extends the design concept of Remote Subscription (RS) by using mobile multicast agents (MMAs), each covering a number of MHs in its service area through tunneling multicast packets received from the multic...

Mobility management is an important task in wireless networks. The Mobile IP protocol provides a basic solution to mobility management in future all-IP wireless network environments. However, Mobile IP suffers from several problems such as triangular routing, long distant and frequent registration update. In this paper, we propose to use the Peer-to-Peer (P2P) network technology to improve Mobi...

In next-generation wireless systems, one of the major features that is different from the current personal communication service systems is the seamless global roaming. The mobile subscribers will be allowed to move freely across different networks while maintaining their quality of service for a variety of applications. To meet this demand, the signaling protocol of mobility management must be...
