摘　　要：为了降低移动自组织网络(MANET)中移动性对路由性能造成的影响,该文提出基于链路预测的可靠MPR选择算法,通过节点间距离和无线传输范围来预测节点与其相邻节点之间的剩余链路有效时间,并提出将剩余链路有效时间(RTTQ)作为OLSR路由协议选择多点中继(MPR)的新的度量方法。利用NS2进行了大量的网络仿真,结果显示采用RTTQ大于临界值的MPR节点,可以提高多项性能,如MPR生存时间、分组交付率(PDR)和平均吞吐量(ATT)。In order to reduce the effect of the mobility of mobile ad-hoc network（MANET）on routing performance, this paper proposed a reliable MPR selection algorithm based on link prediction. The valid time of remaining chain between this node and adjacent node was predicted by both the distance between nodes and the range of wireless transmission. The paper also proposed a new measuring method on selecting multi-point relay by applying the remaining link effective time（RTTQ）as OLSR routing protocol. A lot of NS2 network simulation were conducted in this paper.The results show that a number of properties,such as MPR survival time, packet delivery ratio（PDR） and average throughput（ATT）,can be improved by using the MPR nodes,in which the RTTQ was greater than the critical value.
