The Analysis of Scanning Time in IEEE802.16m´s Handover Procedure

In this paper we analyze the efficiency of scanning process on handover procedure in IEEE802.16 m. Since the .16 m is still under development, the performance evaluation is based on current running standard of 802.16 e. We consider four scan types and evaluate the average scanning time required. In addition, four different handover strategies are utilized to analyze the handover interruption time. The evaluation is done at both parts of handover procedure i.e. network topology acquisition and handover process. The efficient scanning process is proposed to reduce the scanning time and obtained a minimal handover interruption time.
