librsync 是一个运行在Linux下的remote-delta算法库，该算法可以通过网络使远程文件快速即时的更新，而无须发送端有文件的新旧版本。这个算法库可以嵌入到不同的应用程序中。-librsync is a run on the Linux remote-delta algorithm library, the algorithm can be made through the network remote files immediately rapid updates, without having to send documents- both old and new versions. The algorithm library can be embedded into different applications.

由于无线链路和拓扑结构的时变特性，Ad Hoc网络的优化设计面临挑战．为解决这个难题，提出了跨层设计的方法．叙述了Ad Hoc网络跨层设计的概念，介绍了基于跨层方法的一些路由设计思想．提出了跨层路由设计中存在的问题和研究方向．-Since the wireless link and the topological structure of time-varying characteristics, Ad Hoc network optimization design challenges. To address this problem, put forward a cross-layer design approach. Ad Hoc networks described cross-layer design concept, introduced a method based on a number of cross-layer routing design. Proposed cross-layer routing design problems and research directions.
