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, Ad Hoc network has become a research hotspot, which can achieve fast automatic networking. Based on hierarchical Ad Hoc network, this paper proposes a scheme to select the communication mode according to the location of two communication nodes. This scheme establishes a direct communication link between two nodes belonging to different clusters but in communication with each other, avoiding the information going through many unnecessary links. The simulation results in NS-2 show that this scheme can partially improve the network performance and service quality.
