摘要
提出一种给予重连接用户以较高优先级的无线接入控制算法 ,给出一次重连接阻塞率与二次重连接阻塞率两个新的无线QoS指标 .仿真结果表明 ,重连接情况会给网络的性能带来很大的影响 ,重连接优先接入算法有效降低了重连接的阻塞率 。
An algorithm of admission control giving the reconnection requests higher priority was proposed. Two new parameters of wireless QoS , namely blocking rate of reconnecting once and that of reconnecting twice , were introduced. Simulation results indicated that the reconnection phenomenon had a significant impact on the performance of the network. By using the proposed algorithm, the blocking rate of reconnection requests was efficiently reduced and global performance was enhanced.
