RSS Based Adaptive Hysteresis Vertical Handoff Decision Algorithm between WiMAX and LTE to Reduce Ping-Pong Effect

چکیده
In the next generation of wireless network such as long term evolution (LTE) and worldwide interoperability for microwave access (WiMAX), always best connected concept is required. However in many situation handoff failures and unnecessary handoff are triggered causing degradation of quality of service. In this paper our main focus is on the handoff decision problem which affects the number of handoffs which may result in ping pong effect. To overcome this problem we have proposed an RSS based vertical handoff decision (VHD) algorithm with adaptive hysteresis to prevent this ping pong effect and also avoid late handoffs.
