摘要
无线网络中,信号随着距离的增加而逐步衰减,在一定的范围内信号将成为噪声从而对其它节点造成干扰。文章首先定量地给出了节点可以造成干扰的范围,然后用NS仿真软件建立了一个网络模型,对干扰现象进行了仿真,并对仿真结果进行了分析。
In wireless networks, the signal gradually weakens along with the distance increase, and in a certain distance, the signal send from one node will turn to noise and then interfere the other nodes. This paper firstly analyzed the distance that signal can interfere quantificationally. And then build a wireless network model with NS software to simulate the interference phenomena, and analyzed the results of the simulation.
