摘　　要：研究网络安全优化问题,网络经常受到干扰和入侵攻击的威胁。传感器网络系统中网络资源有限,使得无线传感网络运行受到影响,传统的入侵检测系统存在的较高的漏报率和误报率。针对上述问题,提出一种随机路点模型传感网络抗干扰技术。首先建立入侵模型,即采用一个圆来近似入侵区域,所有的传感器都在圆中,并作随机路点运动,遵循移动模型在一个区域内移动,然后利用传感器的随机移动性允许被侵入的传感器在遭到网络攻击侵入后恢复安全的合理状态。仿真结果表明,改进方法可以有效的阻止网络的攻击,抗干扰技术更优,同时系统开销较小,安全性强,并为网络提供了支撑。The sensor network anti interference optimization problem is studied.In the current sensor network system,the sources are limited,the wireless sensor network is easy to receive different attacks,and the traditional intrusion detection systems have high false negative rate and false positive rate.In order to solve this problem,a random road point model is put forward based on the random road point model of sensor network anti jamming technology.First,the intrusion model was built,a round was used to approximate the invasion area with all sensors in the circle doing random road point movement within the region based on the moving model,Then the sensor random mobility allowed the sensor to restore the safe and reasonable state after assault invasion.Simulation results show that the proposed method can effectively prevent network attacks,at the same time,the method requires less overhead,is of strong safety,and does not need any trusted third party or security hardware.
