Research of New Handover Algorithm for IEEE 802.16e

提出一种基于IEEE 802.16e无线网络的新型切换算法。算法充分考虑了IEEE 802.16e的测距、认证、注册等主要使用行为,通过引入业务流(Service Flow)认知,使基于业务流的移动终端处的切换时间达到最小。仿真分析表明,利用标准提出的多种不同能力的交互,算法能够有效降低切换时间。

In this paper, a new handover algorithm for IEEE 802. 16e wirless networks is proposed. The algorithm takes into consideration the main be- haviors of IEEE 802. 16 operation such as ranging, authorization, and registration. That by using service-flows awareness is to minimize the time spent in handover based on theservice flows running at the mobile station. Simulation analysis of the proposed algorithm shows that handovcr time can be effectively reduced by several folds after taking advantage of different capabilities provided by the standard.
