基于AdHoc网络的DWRR亏损数的传输分析

Transmission Analyzing for DeficitCounter of DWRR Base on Ad Hoc Network

AdHoc网络分层结构中的簇头节点,因担负类似于路由器的数据转发功能,其具有的队列调度机制决定了数据包的传输能力、延迟和网络的QoS.本文在亏损加权轮循(DWRR)队列机制基础上,通过业务流组合最佳拟合亏损数来优化其数据传输量,减少端到端的发送时间和延迟时间,理论分析和模拟结果表明该算法具有优越性.

Clusterhead node of layered structure in Ad Hoc network takes on function of data transmitted similar to router. The mechanism of queue schedule which it assumes is very important to enhance transmitted ability of data packet, delay for transmitted and QoS of network. This paper put forwards a method which optimizes utilize of DeficitCounter by combination of operation streame best fitting for DeficitCounter based on mechanism of queue schedule Deficit Weighted Round-Robin(DWRR). The scheme decreases time and delay of data sent from port to port. Analyzing of theory and result of simulation indicates superiority of scheme.
