An Efficient Data Dissemination Protocol for Content-Based Communication in Disconnected Manets

论文摘要

机会网络是由一些特殊主机组成的网络,这些主机必须尽可能多的存储、转发消息以提高与其他主机成功共享文件的概率。在这种类型的网络中,节点可以根据自已的兴趣不断更新其缓存。显然,网络中的主机不能无限制的对消息进行缓存,但若在一个间隔后从缓存中删除消息却会降低携带和发送这个消息给其它主机的可能性。在一些实际情况中,主机可能对刚在缓存中被删除的内容感兴趣。因此,提出一种有效地缓存管理策略是十分重要的。此外,缓存管理还能有效地提高在相同通信区域的消息传递率。本文提出了一个支持稀疏、非连通网络通信的协议,并设计了基于非连通移动自组织网络的内容通知策略和基于消息释放时间的转发策略算法以解决上述提到的问题。实验和仿真结果表明,我们提出的这两个数据传播策略不仅提高了内容传递率,并能使得消息在网络中更加快速的传播。本文还深入探讨了一些属于网络拓扑的问题：端到端系统间如何实现通信。论文同时给出了关于机会网络部署和容忍延时网络的明确解释。
