SUMMARYThe Media-Independent Handover (MIH) standard proposed by IEEE 802.21 can reduce handoff delay when mobile nodes switch between heterogeneous access networks and help Mobile Nodes (MNs) roam seamlessly. The MIH standard is suitable for not only heterogeneous networks but also homogeneous networks. According to the Fast Mobile IPv6 (FMIPv6), during handover initiation, for MNs to get new Access Router (nAR's) prefixes, using Router Solicitation for Proxy Advertisement (RtSolPr)/Proxy Router Advertisement (PrRtAdv) may be time consuming. If there are additional quality of service requirements, the FMIPv6 would require much more time. Based on FMIPv6, this paper proposes a new IS-FMIPv6, which combines MIH services. We also propose a new mechanism for discovering the access route. This scheme reduces the time spent for finding the route to the nAR and increases the probability that FMIPv6 operates in the predictive mode by reducing initiation handoff delay.

“…However, these studies are conducted using simulation tools and signaling analysis only, or present prototypes which implement a subset of the IEEE 802.21 services and similar frameworks for mobility management [4]. Others proposed enhancements to the IEEE 802.21 base standard [5], [6]. In anticipation of next generation networks, several beyond-IEEE 802.21 cross-layer architectures for facilitating mobility management in heterogeneous networks were also proposed as well as several alternative frameworks; see [7]- [9] and the references therein.…”

Abstract-Multiaccess mobile devices and overlapping wireless network deployments have emerged as a next generation network fixture. To make the most of all available networks, mobile devices should be capable of handing over between heterogeneous networks seamlessly and automatically. At the same time, operators should be able to steer network attachment based on their criteria. Although several cross layer mechanisms have been proposed in recent years, only the Media Independent Handover (MIH) Services framework has advanced in any of the established standardization bodies. This paper presents a blueprint for a GNU/Linux implementation of IEEE 802.21. We review the salient points of the standard, introduce our software implementation architecture, detail information gathering in GNU/Linux, and show how our prototype implementation can be used in practice. In contrast with prior published work, this paper presents a real IEEE 802.21 implementation, not an abstracted or reduced MIH-like framework, tested and empirically evaluated over real heterogeneous networks.

“…Buburuzan et al (2007) discuss the integration of broadcast technologies with heterogeneous networks using IEEE 802.21 techniques but do not discuss implementation details. Li et al (2007) discuss simulations of dual-interface MNs using ns-2 that integrates MIPv4 and MIH. However, to the best of our knowledge there is no previous work that describes the implementation and integration details of the MIH function (MIHF) and media independent pre-authentication using an experimental testbed and operational networks.…”

Providing multi-interface device users the ability to roam between different access networks is becoming a key requirement for service providers. The availability of multiple mobile broadband access technologies together with increasing use of real time multimedia applications is creating strong demand for handover solutions that can seamlessly and securely transfer user sessions across different access technologies. In this paper, we discuss how the Integration of IEEE 802.21 services and pre-authentication framework 173IEEE 802.21 standard and its services address the challenges of seamless mobility for multi-interface devices. We focus on a proof-of-concept implementation that integrates IEEE 802.21 services and a pre-authentication framework, to optimise handover performance in two different scenarios. The first scenario is initiated by the mobile node and the second one is initiated by the network. We present the measurement results for realising these scenarios. Finally, we describe the implementation challenges and lessons learned through this exercise. Keywords
