1. A new model for service and application convergence in B3G/4G networks.

Author

Munoz, M. and Rubio, C.G.

Abstract

4G mobile communication networks encompass heterogeneous technologies that can be categorized at different levels according to their access coverage. Personal area, body area, and ad hoc networks are defined at a personal level, WLAN and UWB are examples at a local/ home level, and 3G technologies such as UMTS are technologies at a cellular level. In spite of their heterogeneity, these technologies shall be seamlessly integrated in 4G networks, naturally creating an open architecture. By openness we mean that the network architecture is divided into different layers, and the communication between these layers is performed through open interfaces or APIs. Although this open integration between 4G technologies is normally presented at the lower layers (connectivity and control), integration at the upper layers (service and application) is equally important. In this article we present a new model for service and application integration in 4G networks. This model generalizes the different service and application creation environments defined for each of the previously mentioned technologies, providing a uniform and interoperable framework for 4G services and applications. The model is based on a hierarchical architecture that provides compatibility for services in different technologies and at the same time is able to capture the specific details for each particular technology. The model also defines how 4G applications should be specified. In the last part of this article we present a testbed we have implemented in order to validate this model. [ABSTRACT FROM PUBLISHER]

Abstract

Currently there exist many hand-held devices that support multiple network interfaces (e.g., Bluetooth, Wi-Fi). By composing different networks via such devices one can establish an infrastructure-less B3G environment and enable service provisioning across several networks. One of the key challenges for realizing this view is inter-domain routing. Indeed, given the diversity of involved network technologies and infrastructures, a flexible routing protocol that takes into account their quality properties and dynamics is an important requirement for providing an adequate user-experience. In this paper, we present a flexible quality-aware routing protocol for infrastructure-less B3G environments that enables discovery of routes with optimal bandwidth, delay or cost according to the preference of each client. The protocol is based on the Optimized Link-State Routing (OLSR) protocol and is designed to enable computation of quality-aware routes in the multi-network environments. We detail the protocol, discuss its deployment and provide experimental results.
