摘要
网络级抗干扰是一个新问题,它与网络的拓扑结构紧密相关。本文研究了无线网中干扰相关性,计算了理想拓扑的干扰独立路径数目的数目。网络抗干扰性能的另外一个问题是评估方法,本文提出了基于平面几何的评估方法,其中包含了距离和方位两个参数。该评估方法计算简单,物理意义明确,能很好地反应无线网的拓扑抗干扰性能。
Anti-jamming at the network level is a new problem, which is tightly correlative with network topology. The jamming dependency in the radio network is studied in this paper, and the number of jamming independent paths is calculated. Another problem is how to evaluate the anti-jamming performance of the networks. A new evaluating method is proposed, which is based on the plane geometry and includes two parameters, that is distance and orientation. This method can be easily calculated, has definite meaning, and can commendably reflect the anti-jamming performance of the networks.
