【摘要】 网络拓扑的动态变化是AdHoc网络的主要特点,也是影响通信性能的主要因素。DSR协议是一种按需式路由协议,当发现1个链路断开的时候,就要重新建立1个新的路径,在路径重建的过程中会使包丢失,并且会造成重要的吞吐量的降低。鉴此,提出一种高效的路由协议。在移动预测的机制下,该协议能够选取另外一条后备路径来实现,减少包的丢失。更多还原

【Abstract】 Dynamic topology is one important feature of Ad Hoc,and a key factor affecting communication performance as well. Dynamic source routing (DSR) is an on-demand routing protocol. When it is detected that the link is broken,the source will find a new route. During the route reconstruction,packets may be dropped,which will cause significant throughput degradation. We propose a link breakage prediction algorithm to DSR protocol. The source will maintain backup routes that can be utilized after the primary path breaks. The protocol can significantly reduce the total number of dropped data packets.更多还原
