【摘要】 站点隐藏现象是无线网络中一个主要问题。采用RTS-CTS机制可以避免站点隐藏问题,但该机制不总是有效的,在某些情况下它会给无线网络带来诸如站点屏蔽等新问题。使用网络模拟工具NS2模拟了这些问题,分析了问题产生的原因。更多还原

【Abstract】 The phenomenon of hidden nodes is an important problem in Wireless network and it can be avoided by RTS- CTS mecha- nism. But the mechanism is not always effective, it brings some new problems such as masked nodes into the Wireless network on some condition. This paper provides the simulation for those problems using NS2 and presents the analysis of the reasons.更多还原
