无线多跳网络中支持多媒体QoS的中继节点转发队列调度算法研究

QoS of Multimedia Supported Queue Management Method for Relay Node in Multi- hop Wireless Network

随着网络应用的日益广泛,一个通信网络往往需要支持多种业务。文章针对无线多跳网络,中继节点采用FIFO队列转发数据产生的时延累计效应导致的实时性服务不可用问题,提出了按照数据类型和数据包剩余时延对转发队列中数据包重新排序的策略。此策略能够在保持非实时性应用数据包时延可容忍的情况下,有效降低多媒体数据包的平均传输时延和整个系统的丢包率。

With the increasingly wide range of network applications, a variety of business needs to support in the communication network When relay node serviceble is unavaila in FIFO,this paper raise a strategy to re-order in the queue forwarding the remaining packets . This strategy can maintain the non-real-time application data packet delay in the case it can be tolerated , The average transmission delay of multi-data packet and packet loss rate of the system can be reduced effectively.
