摘　　要：为满足移动用户在切换过程中服务的连续性,针对无线网络的特性,对无线网络中的切换控制算法进行了分析和比较,提出一种简单的自适应资源预留算法,分析该算法对网络性能的影响,并通过仿真比较该算法与传统的资源预留算法对网络性能的影响,验证了该算法的可行性。User mobility management is one of the important components of wireless network. In wireless network, a user should be able to seamlessly obtain transmission resources after handoff to a new base station. This is essential for both service continuity and quality of service assurance. In this paper, we present an algorithm of adaptive resource reservation to reduce the dropping probability for handoff connections and to enhance possibility of new user＇ s admission request. The simulation results and performance analysis show that it can enhance the performance of wireless networks.
