| 摘 要： | 传染路由是DTN中一类较简单的基本路由算法.针对DTN网络环境易变的特点及传染路由的不足提出多队列自适应传染路由,采用多队列方式管理存储空间,利用效用函数对队列内信息进行排序,针对不同队列及网络情况采用相异的转发机制,从而降低网络负载率、提高传输率并降低传输时延,同时可提供简单的QoS.仿真证明本算法优于路由算法Spray andw ait和MaxProp.

| Abstract: | Epidemic routing is one of the basic Simple routing algorithms in the Delay/Disruption Tolerant Networks(DTN).This paper proposes a multi queues adaptive epidemic routing algorithm according to the variable characteristics of DTN and shortcomings of epidemic routing,introduces multi queues into storage managements,adopts the utility function to sort the messages in queue,and uses the different forwarding policy for different queues and network conditions.The proposed routing algorithm can reduce the overhead ratio of networks and communication delay,increase the delivery ratio and offer the simple QoS.The simulation shows that the algorithm is superior to Spray and wait,Maxprop in performance. |
