directional steering meaning in English

方向操纵

The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr , complete routine discovery and maintenance by directional neighbor nodes routing table , source routing and directional steering . the research discovers the application of the directional antenna , compare the omnidirectional antenna can increases the networks " total throughput , obviously reduces the co _ channel interference ( cci ) , multiple access interference ( mai ) , enlarges the nodes " signal and interference to noise ratio ( sinr ) , and because of the high gain of directional antenna can realize the communication with farther distance and less jump , end to end delay can decrease deeply , simultaneously , security of networks can be improved partially , the node energy also can be saved easily by power control
本文提出的定向路由协议ds _ dsr是基于对现有协议dsr的改进下实现的，通过定向邻节点路由表、定向源路由和定向搜索来完成路由发现与维护。研究发现，定向天线的应用，相比全向天线可明显提高网络的总的吞吐量，减少信道干扰、多址干扰，提高信干噪比，且由于定向天线的高增益可实现较远距离、较少跳数的通信，减少了路由发现时间，这样大大减小了传输时延，网络的整体性能得到了不同程度的提高，同时部分地解决安全问题，通过功率控制还可较容易的实现节能的目的。
