Abstract
Vertical handoff decision is an important process in heterogeneous systems. In order to find an appropriate time to trigger a handoff, deciding a stability period before performing the handoff has been studied formerly. In this paper, we introduce the definition of the residence time of a handoff zone (HZ) into the stability period decision method. Then two algorithms, Stability Period Decision Scheme with HZ Residence Time (SPDRT) and Stability Period Decision Scheme Based on Fuzzy Logic (SPDFL), are proposed to adjust the stability period dynamically. Moreover, we apply the two schemes to solve the handoff call queuing problem. Simulation results show that the proposed methods can decrease handoff call dropping rate effectively and adjust the stability period intelligently and sensibly.
