Media-independent handover for seamless service provision in heterogeneous networks
The main seamless mobility principles are identified and used as the basis for further evaluating the potential of the IEEE 802.21 standard to meet the requirements of applications for minimum disruption during an inter-technology handover. Expand
Mobility Management for Femtocells in LTE-Advanced: Key Aspects and Survey of Handover Decision Algorithms
A comprehensive discussion on the key aspects and research challenges of MM support in the presence of femtocells, with the emphasis given on the phases of a) cell identification, b) access control, c) cell search, d) cell selection/reselection, e) handover (HO) decision, and f) HO execution.
