移动式无人值守WSN抗干扰技术研究

摘要

As the wireless sensor network tamper - proof ability is weaker, the wireless sensor network is easy to receive different levels of attacks. Aiming at these problems, the paper put forward a kind of mobile unmanned sensor network anti jamming technology. Based on the online third party trustworthy transceiver wireless sensor network and according the stochastic jump model, all of the sensors only moved within a single region. Using the mobility of the sensor, the invaded sensor was able to rapidly restore the reasonable safety state. The simulation results show that the proposed cooperation scheme, needs small system overhead, can be obtained through comprehensive deploy mode, and is an effective anti interference method.%研究无线传感器网络抗干扰优化问题.由于无线传感器网络分布防篡改能力较弱,使得无线传感网络易收到不同程度的攻击,针对上述问题,提出了一种移动式无人值守传感器网络抗干扰技术.方法主要在第三方可信收发器基础上,依据无线传感器网络的随机跳跃模型,使得所有的传感器只在某一个区域内移动,利用传感器的移动性能,允许被侵入的传感器在遭到网络攻击侵入后能够迅速的恢复安全合理状态.仿真结果表明,提出的合作化方案技术需要的系统开销很小,可通过全面部署的方式实现,是一种有效的网络抗干扰方法.
