现有的移动的ad hoc网络的研究工作大多是基于发送方和接收方之间存在路径的假设。另一方面，分散式移动的系统的应用通常以网络分区为特征。因此，延迟容忍网络的研究在最近几年得到了相当大的关注，作为一种手段，以弥补自组网研究和真实的应用之间的差距。在本文中，我们提出的设计，实施和评估的上下文感知自适应路由（CAR）协议的延迟容忍单播通信在间歇连接的移动的ad hoc网络。该协议基于利用节点作为网络分区之间消息的载体来实现传递的想法。最佳载波的选择是使用卡尔曼滤波器为基础的预测技术和效用理论。CAR协议的大规模性能进行了评估，使用基于社交网络建立的移动模型，一个纯粹的随机模型，和达特茅斯学院的真实的痕迹模拟。
Most of the existing research work in mobile ad hoc networking is based on the assumption that a path exists between the sender and the receiver. On the other hand, applications of decentralized mobile systems are often characterized by network partitions. As a consequence, delay-tolerant networking research has received considerable attention in the recent years as a means to obviate to the gap between ad hoc network research and real applications. In this paper, we present the design, implementation, and evaluation of the Context-aware Adaptive Routing ( CAR) protocol for delay-tolerant unicast communication in intermittently connected mobile ad hoc networks. The protocol is based on the idea of exploiting nodes as carriers of messages among network partitions to achieve delivery. The choice of the best carrier is made using Kalman-filter-based prediction techniques and utility theory. The large-scale performance of the CAR protocol are evaluated using simulations based on a social-network-founded mobility model, a purely random one, and real traces from Dartmouth College.
