从传感器网络节点重要性的角度来研究病毒传播的局域控制,研究表明,通过对少量的重要节点进行免疫,可以抑制病毒的大范围扩散,提高网络的抗蓄意攻击能力.随着免疫效率的提高,使感染传播率临界值增加,同时使病毒感染局域范围控制的效果得到加强.
The local area control of virus spreading is studied in the light of the nodes essentiality in wireless sensor networks (WSN). The research suggests that by immunization to a small amount of control nodes so as to enhance the ability of anti-deliberate attack of the network.With the improvement of the immune efficiency,the epidemic threshold increases,and the effect of local area control strengthens.
