Internet of Things has resulted in ubiquitous computing, where all IoT devices are connected almost all the time, to provide continuous services. This makes the network prone to several attacks, one such attack being the Direct Denial of Service (DDoS) attack. Jamming, which is the use of malicious nodes to deliberately lower Signal to Noise ratio (SNR), is a subset of DDoS attacks, which affects physical layer devices and channels, and can cause errors in the upper layers. Anti-jamming techniques, which are used to mitigate the effects of jamming, must be analyzed from the security and efficiency perspective. In this paper, anti-jamming techniques and protocols, viz. JAM- Jammed Area Mapping, Channel surfing and spatial retreat, channel hopping, reactive jamming detection and trigger node detection; are compared with respect to security and efficiency parameters. The suitable techniques are finally selected for specific use cases. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
