干扰对网络通信有着重要的影响，因此人们一直在努力降低干扰，虽然干扰的定义很明确，但对于干扰模型的研究却众说纷纭。主要有两种模式。一种是基于节点的数量，另一种是基于信号强度。然而，前一种模型不能真实地反映真实的干扰情况，而后一种模型则难以假定干扰节点的分布和相应的参数。针对这一问题，本文提出了一种新的干扰模型，该模型基于外部干扰能量，并引入了干扰源传输概率。仿真结果表明，我们的模型很好地反映了现实。
Interference has a significant impact on the network communications; hence efforts have been made to reduce it. Although interference has an unambiguous definition, researchers have different opinions about the interference model. There are mainly two kinds of models. One is based on the number of nodes, and the other is based on the signal strength. However, as discussed in this paper, the former kind of models cannot factually reflect the real-world interference, and for the latter, it is difficult to assume the distribution of interfering nodes and the corresponding parameters. Aiming at this issue, we propose a new interference model which is based on the extraneous interfering energy and adopts the probability of interferer transmission. Simulation results illustrate that our model reflects the reality well.
