This paper identifies some interesting problems in mobile group communications regarding dynamic group membership due to member joining and leaving, dynamic locations due to node mobility, and dynamic networks due to node/link failures. These problems are solved by proposing a ring-based hierarchy of proxies with bi-directional tokens. The proposed hierarchy is a combination of logical rings and logical trees, which takes advantage of the simplicity of logical rings and the scalability of logical trees. More importantly, such a combination makes the proposed protocol based on this hierarchy more reliable than the existing tree-based protocols. Theoretical analysis and simulation studies of the proposed protocol show that: (1) It scales very well when the size of a group becomes large; (2) It is strongly resilient to failures that occur in the network. It is particularly suitable for those service providers and network operators which have deployed their machines in a hierarchical setting, where each machine can be locally configured to know the information about its sibling and parent machines.

“…Different integration strategies for mobile Internet have been investigated by many researchers, such as Unified Wireless Networks Architecture [18], System Architecture for Mobile Communications Systems [20], All-IP Wireless/Mobile Network Architecture [22], and FIT-MIP Global System Architecture [19]. Based on these architectures, we propose a basic mobile Internet architecture called the 4-Tier Integrated Network Architecture for Mobile Internet Computing in Figure 1, which are illustrated as follows.…”

“…The OSA API, specified jointly with the Parlay group in IDL, Java, and WSDL, provides an abstract view of the core network functionality, such as (multimedia) call control, data session handling, messaging, user location, charging, account management, presence, and policy management. In addition, the API supports capability and application management through a so-called framework API [4]. The API is provided by an OSA gateway to the applications residing on dedicated application servers.…”

In light of the increasing acceptance of the notion of Next Generation Networks (NGN), which will result from the convergence of the fixed and mobile telecommunications, Internet, and entertainment sectors, there is a need for the realization of next-generation service delivery platforms to allow seamless and adaptive provisioning of multimedia information and communication services to mobile users. This means that in such an NGN environment different end systems, access networks, and service platforms have to be integrated. For this highly heterogeneous communications and services environment, we propose a self-adaptive service provisioning middleware framework (ASPF), which, by interoperating with existing wireless and wireline service delivery platforms, aims to enable seamless omnipresent service provisioning to mobile users anywhere, anytime, and in any context. The ASPF is intended to "liberate" applications from space and time limitations, networks, platforms, and device dependences, minimize time-to-market constraints, and eliminate major hurdles that hinder the rapid deployment of new mobile services and applications. Key to this goal is interworking/integration with current SDPs, such as IN/CAMEL, OSA/Parlay, and the emerging IMS.
