Abstract: IEEE 802.16e is a new technology that provides users with broadband wireless mobile access to network. By analyzing IEEE 802.16e handover process, this paper introduces a new handover algorithm that can fulfill the requirement of quality of service and can work in practical system. This algorithm solves two key problems in handover process: handover triggering and target selection. Analysis shows that this algorithm can guarantee MS’s mobility as well as network quality of service.

Key words: IEEE 802.16e, handover, time delay, Quality of Service(QoS)
