Detection of selective forwarding attacks based on adaptive learning automata and communication quality in wireless sensor networks

International Journal of Distributed Sensor Networks, 2018
Wireless sensor networks face threats of selective forwarding attacks which are simple to implement but difficult to detect. It is difficult to distinguish between malicious packet dropping and the normal packet loss on unstable wireless channels.
