table antenna 中文意思是什麼
table antenna
解釋
臺式天線-
Switch on phone a and place it on the table such that the antenna ( the pokey thing at the top ) is about half an inch from the egg
開啟手機a並將之放在桌上使其天線部分（頭上突起部分）距離蛋杯半英寸。 -
Switch on phone a and place it on the table such that the antenna ( the pokey thing at the top ) is about half an inch from the egg ( you may need to experiment to get the relative heights correct - paperbacks are good if you have any - if not you may be able to get some wood off cuts from your local hardware shop )
打開手機a並把它放到桌上，讓它的天線（頭上凸起的部分）離雞蛋大約半英寸遠（你需要試著調整來得到它們正確的相對高度-如果你有一些書本將會很好-如果沒有書本你可以從本地的雜貨店弄一些鋸好的木塊） 。 -
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協議ds _ dsr是基於對現有協議dsr的改進下實現的，通過定向鄰節點路由表、定向源路由和定向搜索來完成路由發現與維護。研究發現，定向天線的應用，相比全向天線可明顯提高網路的總的吞吐量，減少通道干擾、多址干擾，提高信干噪比，且由於定向天線的高增益可實現較遠距離、較少跳數的通信，減少了路由發現時間，這樣大大減小了傳輸時延，網路的整體性能得到了不同程度的提高，同時部分地解決安全問題，通過功率控制還可較容易的實現節能的目的。 -
