| Abstract: | 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. |
