摘　　要：着重研究在通信链路易中断的稀疏Ad hoc网络环境中的数据传输问题。提出了链路预补偿算法,首先给出了关键节点的定义与探测算法,然后给出了功率补偿算法,通过增大补偿节点的功率,增强关键节点周围的连接度,进而提高数据的接收率和吞吐量;并且在NS2模拟器中,对该算法搭建仿真平台进行了性能评估。仿真结果表明,链路预补偿算法能够提高网络的吞吐量和数据接收率。The research focuses on communication problem in sparse Ad hoc networks where links easily disrupt. This paper presented links precompensation. Firstly gave the definition of critical nodes and the method to detect them, then proposed power control compensation algorithm, through improving nodes＇ power to improve the network connectivity and eliminate the impact of the critical node. In the NS2 simulator, designed simulation platform for the scheme. The results show that the links precompensation algorithm can improve network throughput and data delivery ratio.
