The user-perceived performance of voice services can be improved if the handover (HO) criterion is designed to consider the mean opinion score (MOS). However, this involves several problems, such as the measurement difficulty of the MOS, the detection difficulty of the MOS degradation factors, and the requirement of cross-layer design. To solve these problems, we propose an abstracted R-factor-based...
This paper proposes a handover scheme using uplink and downlink channel quality information in order to improve the uplink channel performance during a handover process. The proposed scheme has two main features. First, the proposed scheme adopts the scanning process without an association process in order to obtain an uplink channel quality. Second, it designs the handover triggering and decision...
In the heterogeneous wireless networks, the optimal network selection problem is one of the key issues. QoS aware path selection scheme is proposed in this paper, which estimates required bandwidth ratio based on the QoS requirements of target service and the SINR of each path. The proposed scheme can select the optimal path which can satisfy the QoS requirements among many heterogeneous wireless...
