摘要 典型的容迟网络(DTN)场景常表现出大延迟、易中断、高误码率等特点,其中高效节能的路由算法更是一个亟待解决的问题.现有方法主要是通过发送多个副本来提高数据传输的可达性概率,但网络开销很大.为了同时兼顾成功投递率、网络延迟和网络开销,文中提出了基于Markov位置预测模型的DTN路由算法(喷射转发算法).该算法根据节点经过路径的历史信息,用2阶Markov预测机制预测目的节点可能的位置,针对该位置进行多路径的贪婪转发,使包有方向地扩散,减少网络中包的副本数.采用多副本转发的混合发送模式,在保证成功投递率的基础上,有效地减少包副本数,弥补了使用单一模式时不能兼顾网络开销和成功投递率的不足.仿真结果显示,在小节点密度、节点移动速度较快的网络环境下,与spray and wait算法相比,喷射转发算法能有效地提高成功传输率,减小网络开销.
