| 摘 要： | 针对宽带无线接入网络,提出了一种动态带宽管理分配机制.当移动节点从原用户站移动到新的用户站时,如何保证原连接的QoS需求.另外,在带宽资源不足的情况下,让实时性的服务具有较高的带宽使用优先权,以降低转移呼叫中断概率.仿真结果表明,提出的动态带宽管理分配机制,通过合适的参数配置,可以表现出应有的性能.

| Abstract: | A new mechanism of dynamic bandwidth management is proposed for broadband wireless access network.: How to transfer QoS link from the former Subscriber Station(SS) to new SS when the mobile node moves from former SS to the new SS;And let real-time services get high priority to acquire bandwidth to reduce handoff call blocking probability when the bandwidth resource is insufficient.Simulation results show that the proposed mechanism of dynamic bandwidth management can meet the proposed abilities when relativ... |
