Enabling technologies for the ‘always best connected’ concept

Abstract

Summary'Always Best Connected' (ABC) is considered one of the main requirements for next generation networks. The ABC concept allows a person to have access to applications using the devices and network technologies that best suits his or her needs or profile at any time. Clearly, this requires the combination of a set of existing and new technologies, at all levels of the protocol stack, into one integrated system. In this paper, a considerable set of the technologies, that are expected to play a key role towards the ABC vision, are presented. Starting from a reference architecture, the paper describes the required enhancements at certain levels of a traditional protocol stack, as well as technologies for mobility and end-to-end Quality of Service (QoS) support. The paper concludes with a case study that reveals the advantages of the ABC concept.

An intelligent agent-based scheme for vertical handover management across heterogeneous networks

“…It plays a vital part in fulfilling users needs, balancing resource utilization, and maximizing network performance. In order to keep users always best connected [39], various QoS parameters are con- sidered that affect the vertical handover decision. Received signal strength (RSS) is a traditional and unavoidable factor for making handover decisions.…”

A negotiation framework for content distribution in mobile transient networks

“…In such case the basic objective aims at providing constant connectivity to the network. If an interface goes down, the multimode device acting as access router will forward the data packets through a different interface without even being noticed by the user (Passas et al, 2006). Such multihoming facility is of special relevance in wireless environments where short radio outages deny a fluid service for the user.…”

Common Radio Resource Management Algorithms in Heterogeneous Wireless Networks with KPI Analysis

“…4G, LTE, and WiMax) [4]; in order to achieve gain of such B3G networks, the available radio resources must be managed in a proper way. This trend introduces a new algorithms for managing the radio resources, that take into considerations the overall available resources offered by several RANs, such algorithms from the common perspective is called as Common Radio Resource Management (CRRM) algorithms, briefly the concept of CRRM uses a twotier Radio Resource Management (RRM) model [5], including of RRM and CRRM entities as clarified in figure 2. Generally, Common Radio Resource Management (CRRM) involves a set of functions that are engineered to achieve a coordinated and efficient utilization of the available radio resources in complex scenarios that are including heterogeneous networks.…”
