中文摘要：

由于节点的移动性、稀疏链路和节点的不可靠,受限网络节点之间在大部分时间处于断开状态,现有的同步路由方法不能适用这种实际情况,所以必须从异步角度来考虑这类网络环境下的路由问题.文章完全从异步的角度思考无线自组织网中的路由问题,利用分组转发的历史信息智能做出路由决策,并研究中继节点数量对性能的影响,以减少由于复制大量分组而产生的网络流量.文章详细介绍了作者提出的方法,并通过仿真实验和一些相关算法进行比较,分析算法性能.

英文摘要：

For the reason of the mobility the time links in challenged networks are ,fallibility of nodes, and the sparsity of Links, most of disconnected. Traditional synchronous routing methods are unsuitable for this circumstance, thus we should consider the routing problem of challenged networks in an asynchronous way. This paper proposes a totally asynchronous routing algorithm, which uses the forwarded history of the messages to make routing decision. This method could decrease network traffic caused by message flooding. In addition, the authors study of the influence of the number of relays on the performance. This paper elaborates the method and analyses the performance of the method by comparing the simulation result with some other methods.
