TLDR
In this paper, the authors present IEEE 802.21, a new emerging standard aimed at providing a framework for media-independent handover among heterogeneous networks, and discuss how the MIH framework can help handover management for the integrated network.Abstract:
Recently there has been much effort, in both academia and industry, to integrate a plethora of wireless technologies in order to provide ubiquitous broadband access to mobile users. Handover management is still one of the most challenging issues to be solved for seamless integration of wireless networks. This article addresses the integration of IEEE 802.11 WLANs and IEEE 802.16 WMANs, focusing mainly on the handover management aspects. First, we describe architectures, futuristic application scenarios such as the envisioned heterogeneous multihop wireless networks (HMWNs) and moving networks, as well as the related research issues. Second, we present IEEE 802.21, a new emerging standard aimed at providing a framework for media-independent handover(MIH) among heterogeneous networks. Finally, we discuss how the MIH framework can help handover management for the integrated network.read more
