摘    要:为对抗无线传感器网络中存在的强针对性的智能型干扰攻击,基于多种扩频技术提出了一种混合跳频扩频、非协调直接序列扩频以及非协调跳频扩频的抗干扰攻击方法。为解决传统扩频技术需要提前共享密钥的限制,在网络初始化阶段使用非协调跳频扩频进行网络通信;为避免持续使用非协调扩频跳频带来的高能量消耗问题,发送节点与接收节点在非协调扩频跳频模式下生成跳频序列,即可进行传统跳频扩频;通过非协调直接序列扩频技术进一步增强对抗干扰攻击的性能;使用OPNET并基于多种干扰攻击模型进行网络仿真,评估所提出的混合抗干扰攻击方法的性能。仿真结果表明,在环境恶劣情况下,并受到强针对性的智能型干扰攻击时,网络仍能保持较低的丢包率,故所提出的混合抗干扰攻击方法能有效地抵抗无线传感器网络中的干扰攻击。

关 键 词:无线传感器网络  抗干扰攻击  非协调跳频扩频  非协调直接序列扩频

Abstract:In order to resist the targeted intelligent interference attack in wireless sensor networks, this paper proposes an anti-jamming attack method based on hybrid frequency hopping spread spectrum, uncoordinated direct sequence spread spectrum and uncoordinated frequency hopping spread spectrum based on multiple spread spectrum techniques. In order to solve the limitation of sharing key in advance in traditional spread spectrum technology, uncoordinated frequency hopping spread spectrum is used for network communication in the initial stage of the network. In order to avoid the high energy consumption caused by the continuous use of uncoordinated spread spectrum frequency hopping, the nodes of both sides of communication generate frequency hopping sequence in uncoordinated spread spectrum hopping mode and then transfer to traditional frequency hopping spread spectrum communication. The performance of anti-jamming attack is further enhanced by uncoordinated direct sequence spread spectrum technology. Using OPNET and network simulation based on multiple interference attack models, the effectiveness of the proposed hybrid anti-interference attack method is verified. The simulation results show that the proposed hybrid anti-interference attack method can effectively resist interference attacks in wireless sensor networks because the network can still maintain a low packet loss rate when it is attacked by strong targeted intelligent interference attacks.
Keywords:wireless sensor networks  anti-jamming attack  uncoordinated frequency hopping spread spectrum  uncoordinated direct sequence spread spectrum
