摘要
移动自组网(MANETs)使用全向天线数据传输时,传输距离受限且信号容易受到严重干扰和窃听。为了克服这些缺陷,研究者提出了采用基于定向天线的移动自组织网解决方案。定向天线配对是定向自组网拓扑管理的关键问题。考虑到无线链路的使用情况,提出了一种基于链路利用率的定向天线配对算法。它能够根据网络监测的链路流量动态调整定向自组网中不同节点间通信的定向天线对,以提高网络链路的利用效率。
When mobile ad hoc networks(MANETs)use omni-directional antenna data transmission,the transmission distance is limited and the signal is susceptible to serious interference and eavesdropping.In order to overcome these drawbacks,a mobile self-organizing network solution based on directional antennas is proposed.Directional antenna assignment is a key issue in directional topology management of ad hoc networks.Taking into account the use of wireless links,a directional antenna assignment algorithm based on link utilization is proposed.It can dynamically adjust the directional antenna pairs of the communication between different nodes in the directed ad hoc network according to the link traffic monitored by the network,so as to improve the utilization efficiency of the network link.
