摘要
Ad Hoc网络是无须中心设施的无线网络,网络节点依靠自身寻找路由,这使得路由协议得到更多关注。为了考察传输层协议对路由性能的影响,文章在研究Ad Hoc网络典型路由协议工作原理的基础上,利用NS2网络仿真软件,分析了它们在UDP、TCP两种传输层协议下的性能变化。结果表明,采用UDP协议时,AODV总体性能对DSDV优势明显,而使用TCP协议时,AODV的性能略逊于DSDV。
The Ad Hoc network is a kind of wireless network independent of central facilities, and its network nodes search routing by themselves. These make the routing protocols attract more attention. For investigating influences of transport layer protocols on routing protocols performance, this paper, based on detailed the principle of typical routing protocols for Ad Hoc network and UDP or TCP, analyzes their performances by using the network simulation software NS2. The results show that the overall performance of AODV is evidently superior to that of DSDV in UDP, but slightly poor in TCP.
