中文摘要：

针对间歇性连通的移动网络环境，提出了一种新的DTN路由协议IEDR。其整合以往DTN路由算法中的设计经验，充分利用节点间相遇的机会交换数据，提高数据传达率并降低传输延迟，同时将资源开销控制在可接受的范围内。IEDR还尝试将无线接入点作为辅助数据传播的有效途径，利用接入点间高速互联的特性为数据在广大地域内的高效传播提供便利。仿真结果表明，与一些经典路由协议相比，IEDR达到了更好的效能。

英文摘要：

To cope with u.n-ideal conditions in mobile network where connectivity is only intermittent, a novel DTN （delay tolerant network） routing protocol, IEDR, was proposed, which incorporates experiences gained before and strives to fully utilize node contacts for data exchange, in order to maximize delivery ratio and minimize delivery delay, while still with controlled overhead. Additionally, IEDR attempted to use wireless access points for data propagation, as access points were supposed to be widely deployed and interconnected with high speed, providing an opportunity to efficiently distribute data in large areas. The evaluation proves that IEDR is better than many classic DTN routing protocols.
