%X The lack of consideration of handoff symmetry in traditional vertical handoff technology leads to the high computation complexity of handoff procedure.Thus,the Background Scanning based Moving Average Forecasting Scheme (MAFS) and Gradient Prediction Scheme (GPS) were proposed.MAFS firstly calculates the average value of the received signal strength,and counts the number of signal strengths which are small than average value.MAFS finally triggers the handoff procedure.GPS starts the procedure of handoff thr...
