摘　　要：针对容迟与容断网络中的单播通信问题,提出了一种自适应感知路由协议(adaptive context aware routing protocol,ACRP);并引入卡尔曼滤波理论,给出最优的消息轮渡节点选取策略。仿真实验表明,与常见的单副本拷贝或多副本拷贝协议相比,提出的面向情境感知的自适应路由协议拥有更好的传输性能和稳定性。This paper presented a self-adaptive context aware routing protocol （SACARP） for the unicast communication in delay amt tolerant networks. Meanwhile, according to the real-time context information of DTN, it introduced the Kalman filter theory to predict the information state of mobility for the optional message ferrying node, and then gave the optimal selection strategy of the message felxying nodes. The simulation experiments show that, compared to the familiar single-copy and multi- copy protocols, the SACARP proposed in this paper has better transmission performance and stability, especially when the net- work is fl＇ee, the protocol would guarantee a good performance with fewer connections and less buffer space.
