一种支持多播的分布式资源接纳控制方法

A Distributed Resource Admission Control Mechanism Supporting Multicast for MANETs

摘要:

提出了一种应用于移动Ad Hoc网络的分布式资源接纳控制机制,在目的节点和中间节点部署不同的资源接纳控制模块,能以接近通话或者分组传输的时间间隔适应网络的动态变化,为业务提供较好的QoS保障,并且能够支持多播及接收者异质性。仿真结果表明,添加资源接纳控制机制后,时延、抖动及丢包率分别降低了25.75%,51.76%和24.15%。

Abstract:

A distributed resource admission control mechanism for mobile Ad Hoc networks is introduced for QoS guaranteed, which deploys different control modules at destination nodes and intermediate nodes, can adapt to dynamic changes by close to call or packet transmission time granularity. Meantime, it can also support multicast and meet the heterogeneity of receivers. Simulation results show that delay, jitter and packet loss ratio has reduced by 25.75%,51.76% and 24.15% after adapting resource admission control mechanism.
