摘要
WiFi网络和无线传感网共存时会产生同频干扰。分析了一种频率捷变的抗干扰技术的不足。提出一种基于频率捷变的分布式自适应抗干扰技术,给出了重度干扰时采取的干扰避免流程,采用分布式的干扰避免方法使得干扰区节点和非干扰区节点工作在不同的信道上。仿真结果表明该方法能有效的避免重度干扰,保证网络通信的可靠性。
Co-frequency interference produced in WiFi and wireless sensor network co-existence network. An anti-interference technology based on frequency agility, and its weaknesses were pointed out. The paper proposed a distributed adaptive anti-interfer- ence technology based on frequency agility. It included interference detection and interference avoidance. According to the strength of interference, the new anti-interference technology used different interference-avoided methods. The simulation results show the proposed anti-interference technology can avoid interference effectively, and it ensures the reliability of wireless sensor network.
