Digital Filter Design for Jamming Mitigation in 802.15.4 Communication

Jamming attackers can dramatically increase attack efficiency and stealth by randomly or periodically cycling the jamming transmission on and off, attacks respectively known as random and periodic jamming. In this paper, the authors analyze the impact of such attacks on the IEEE 802.15.4 communication protocol, commonly used in wireless sensor networking applications, and show that the cycling behavior introduces a narrow spectral component into the received signal. They propose the inclusion of a digital filter at the receiver side to effectively eliminate this spectral component, and they discuss the benefits involved in this filter design.
