“…The focus of this work is on the cost of signaling, with emphasis on NSIS framework. Nevertheless mobility aspects are not covered in the aforementioned publication [4]. To address such issue, Neves et al [9] evaluate a seamless handover procedure between WiMAX and Wi-Fi access technologies, optimized with the MIH framework implemented in WEIRD.…”

“…This architecture supports seamless mobility in BWA networks, integrates different technologies, such as WiMAX and Wi-Fi, and thus, it is appropriate for next generation network environments. The architecture integrates QoS functionalities, specifying mechanisms to enable the complete combination of mobility and QoS, using an extension of the Next Steps in Signaling (NSIS) framework with IEEE 802.21 information [4] [5]. We present the final and overall results of an advanced mobility scenario for next generation networks using a real demonstrator.…”

Although IEEE 802.16 has emerged as one of the major candidates for next generation networks, it is also clear that in the near future the combination of several technologies will be required. In this sense, the support of mobility in heterogeneous environments, addressing broadband wireless, is one of the main requirements in next generation networks. This paper evaluates an architecture based on the recently standardized IEEE 802.21 framework, integrating both mobility and Quality of Service (QoS) mechanisms, through an advanced mobility scenario using a real WiMAX testbed. This architecture supports seamless mobility in broadband wireless access (BWA) networks, integrates different technologies, such as WiMAX and Wi-Fi, and thus, it is suitable for next generation network environments.The results, obtained through real experimentation of the implemented architecture, show that it is able to provide QoS under dynamic scenarios, with fast integrated QoS and mobility signaling.

In a multi-domain Internet that offers Quality of Service guaranties, there is the need of signaling among the domain entities that are responsible for the management of Quality of Service. Because different domains have different network protocols and topologies, there is no solution that is able to signal these entities using an off-path approach and, in particular, that is able to interwork with the on-path signaling mechanisms. The HyPath approach extends the NSIS framework and its interactions with the local routing protocols to achieve offpath signaling in these hybrid environments. This document presents HyPath and its evaluation on a test-bed, showing that the mechanisms proposed have the potential to perform off-path signaling without introducing an excessive overhead in the network.
