Adaptive Handover Hysteresis and Call Admission Control for Mobile Relay Nodes

In this paper, the authors are equipping a wireless network with a mobile relay node is to support broadband wireless communications for vehicular users and their devices. The high mobility of vehicular users, possibly at a very high velocity in the area in which two cells overlap, could cause the network to suffer from a reduced handover success rate and hence, increased radio link failure. The combined impact of these problems is service interruptions to vehicular users. Thus, the handover schemes are crucial in solving these problems. In this paper, they first present the adaptive handover hysteresis scheme for the wireless network with mobile relay nodes in the high-speed train scenario.
