Gain Analysis of Adaptive MIMO Semisoft Handover in LTE-OFDM Systems

Mobility-Aware Video Streaming in MIMO-Capable Heterogeneous Wireless Networks

“…By means of modeling possibilities, the authors showed both improvements and deterioration of duration of handover procedure with the use of MIMO in radio systems. In [22], the authors consider a novel adaptive multi-input multioutput (MIMO) semisoft handover technique for the quality of service (QoS). Semisoft handover permits both hard and soft handover advantages for OFDM networks.…”

“…We first analyzed the handover-success probability ( ) and the handover-failure probability ( ) according to the MN initial state and based on the transition probability; then, we simulated the random-walk procedure with a sample size of 10,000 to verify the result of the analysis. can be calculated when the MN moves to one of the following states in Area C: State(1, 1, 0 Video-streaming delay according to initial states Video-streaming delay based on proposed scheme Video-streaming delay based on hybrid scheme Video streaming based on the proposed scheme (MUX+DIV) Video streaming based on the proposed scheme (MUX) Video streaming based on the proposed scheme (DIV) Video streaming based on semisoft handover scheme [22] Video streaming based on eFMIPv6 Video streaming based on FMIPv6 State (2,1,2). can be calculated when the MN performs handovers for areas other than Area C. Figure 12 shows the video-streaming delays of our proposed scheme and the hybrid scheme according to the initial state; the initial states are possible locations for the MN.…”

“…Inspects of comparison analysis between the proposed scheme and semisoft handover scheme, our proposed scheme is seamless and practical with even partial information compared with the semisoft handover scheme with global information, since is the number of a few MUX capable nodes in the proposed scheme while is the number of total nodes of whole network in semisoft handover scheme.
