摘要 在移动模型不可预知的延迟容忍网络(DTN)中,有效地传输数据是非常困难的。由于连接的频繁断开和缺乏对网络动态结构的了解,传统的传输策略很难发挥效用。通过分析和比较目前DTN中常见的转发机制,提出一种新的映射—编码—分发(MCR)分层架构。仿真结果表明:其在不同的DTN环境下均具有较好的性能。 In unpredictable delay tolerant networks (DTN) of mobile model, it is very difficult to transmit datas. Because disconnections are prevalent and lack of knowledge about network dynamic structure, traditional transmission strategy is not functioning. Through analyzing and comparing current forwarding scheme in DTN network and a novel framework--map-code-replicate ( MCR ) is proposed. Simulation result shows that this framework performs well in different DTN environment.
