Due to an explosive growing demand for higher data rates that have led to the 5th generation of mobile networks, Network Coding-enabled mobile small cells are observed as a promising technology for 5G networks that can cover the
urban landscape by being set up on-demand at any place, and at any time on any device. Despite the benefits of network coding technology on these networks, pollution attacks should be addressed before network coding technology reaches its full potential in 5G mobile small cells. In this paper, we have proposed an intrusion detection and prevention scheme which is able not
only to detect and prevent pollution attacks but also to detect the exact location of adversary nodes which are the source of pollution attacks.
