IEEE 802.21: A Shift in the Media Independence
In this paper, the authors present their vision on future uses of the Media Independence paradigm developed within the IEEE 802.21. They argue that this specification is an excellent starting point for future applications that require the handling of heterogeneous technologies. The current IEEE 802.21 standard facilitates media independent handovers by providing higher layer mobility management functions with common service primitives for all technologies, thus hiding the technology specifics of the lower layers. In this paper, they claim that such a media independent abstraction can be useful for functions other than handovers and advocate for extending the IEEE 802.21 standard to cover these additional functions.
