摘　　要：近几年,Ad Hoc网络成为一个研究热点,它能够实现快速自动组网。文章在分层结构Ad Hoc网络的基础上,提出了一种根据两个通信节点位置来选择通信方式的方案。该方案建立属于不同簇,但在彼此通信范围内的两个节点之间的直接通信链路,避免信息经过许多不必要的链路。在NS-2中的仿真结果表明,此方案可局部改善网络的性能以及服务质量。In recent years, the Ad Hoc network has become a focus for research. It can be established automatically and quickly. Based on Hierarchical framework Ad Hoc network, this paper describes a scheme in which the two communicational nodes select communication mode according to their position. This scheme constructs a direct communication channel between the two communication nodes belonging to different cluster, thus in each other＇s communication area, to avoid the communication passing through some unnecessary links. The simulation result based on Network Simulator Version 2 indicates that this scheme can improve, to some extent, the performance and service quality of the network .
