In next generation wireless systems, achieving seamless service continuity when transitioning between heterogeneous networks is a challenging task. An approach to optimize these handover procedures through the introduction of a standardized framework is followed by the IEEE 802.21 working group. The Media Independent Handover (MIH) function of IEEE 802.21 is mainly designed for "Client-network" scenarios and not applicable to multi-hop connectivity models. In this paper, the authors propose an extended MIH model for accommodating multi-hop mode of operation in heterogeneous mobile networks.
