Optimizing handover decision and target selection in LTE-A network-based on MIH protocol

This paper proposes a new approach for optimizing the handover decision and the target network selection process in 3GPP LTE-Advanced network. We aim to manage load state between LTE-Advanced cells, as well as between different existing Radio Access Technologies (RATs). In fact, a well-balanced load ensures the prevention of a congestion state. With Fourth generation networks, like LTE_A, the access layer includes all existing RATs. All of them are controlled by a unique core network. To managewith more flexibility and different interworked RATs, we adopt the MIH 802.21 protocol. Our proposed scheme offers to the Radio Resources Management (RRM) entity a dynamic and autonomous aspect in order to maintain the network performance. Finally, the performance of the proposed scheme is evaluated using simulation analysis.
