RSS, Hysteresis plus Threshold: A handover is made if the RSS of a new BS exceeds that of thecurrent BS by a hysteresis margin h and the signal strength of the current BS is below a thresholdT (choose BSnewif Pnew> Pold+ h and Pold< T ). In Fig. 2.3, the handover will occur at pointC if the threshold is either T1or T2, and will occur at point D if the threshold is T3.
