- 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。 - Previous research on the ad hoc network almost aim at omnidirectional antenna of all receivers and transmitters , or as a default attribution . in my thesis , firstly i describe the advantages of the directional antenna at many aspects which including spatial division multiple access ( sdma ) , the antenna gain , anti - interference etc . and analyze the possibility about the directional antenna used for the ad hoc networks , secondly i study its multiple access and routine protocols using the directional antenna . and compare the protocol difference and network " performance between omnidirectional and directional antenna in particular environment
首先阐述了定向天线在网络空分复用( sdma ) 、天线增益、抗干扰等方面的的优势,分析了定向天线用于移动自组网的可行性,接着重点研究了基于定向天线的多址接入协议和路由协议,分析了与全向天线在组网和协议实现中的异同点和优缺点,并对特定的环境下的网络性能作了对比。
