Routing Protocol for Low power and Lossy network (RPL) topology attacks can downgrade the network performance significantly by disrupting the optimal protocol structure. To detect such threats. we propose a RPL-specification. obtained by a semi-auto profiling technique that constructs a high-level abstract of operations through network simulation traces. https://www.nacrack.com/deal-alert-Dea-Eyewear-Jemma-deal-zone/
