容迟网络中链路特性是影响网络性能的一个因素,而有些引起链路中断的因素有确知的和不可确知的,针对DTN网络中确定性事件影响链路中断的统计特性问题进行了分析,采用寻找两节点苏醒时间的交集即为两节点间可通信时间的方法,得到了无线链路的连接性特性随时间变化的规律。
The characteristic of wireless link in the DTN has an important influence on the performance of networks. The deterministic and opportunistic events can lead to the link interruption in the DTN. The connection of wireless links was analyzed when deterministic interruption events exist. By finding common recovery time of two-node, the rules was gotten that connectivity characteristic of the wireless networks with changes over time.
