摘要
同等功耗下,定向天线能够产生更高的增益,提供更大的传输范围,提高网络的空间复用度和吞吐量,天线选择的方向性又降低了邻近结点之间的相互干扰,采用定向天线能够给移动自组网带来潜在性能的提高。对基于定向天线的移动自组网路由协议进行研究,简单介绍了定向天线,总结了引入定向天线产生的路由问题,对现有的一些典型定向路由协议进行了分类、介绍和比较,最后对引入定向天线带来的好处进行了分析。
With the same power consumption,the directional antenna could produce higher gain,provide greater transmission range,and improve the network spatial reuse and throughput as well.Furthermore,the directional selectivity could also reduce the co-channel interference of neighboring nodes,and directional antennas could bring potential performance improvement to the mobile Ad Hoc networks.This paper gives a brief presentation of recent research on routing protocols in mobile Ad Hoc networks with directional antennas,then a description of directional antennas,and a summary of routing problems resulted for directional antennas.The existing typical directional routing protocols are classified,presented and compared.Finally,this paper,analyzes the benefits in introduction of the directional antenna.
