摘要
针对Ad Hoc网络拥塞问题提出了一种新的主动队列管理方法.该方法首先基于离散时间Erlang消失系统建立了转移概率矩阵,并且推导了平均队长的数学表达式.同时结合节点服务率和业务流到达率给出了系统的丢包策略,最后通过仿真实验深入研究了丢包率与利用率之间的关系,结果表明它们之间成正相关.
In order to mitigate the congestion of Ad Hoc network, a novel active queue management method is proposed. In this method, transition probability matrix is presented base on discrete time Erlang loss system at first, and the mathematic formula of average queue length is derived. Then, the drop strategy is designed with node service rate and traffic arrive rate, and a simulation was conducted to research on the relationships between drop rate and utilization rate. The result shows that drop rate is positive correlation with utilization rate.
