DE2RA-RPL: detection and elimination of resource-related attacks in IoT RPL-based protocol.

Resource Attacks in the Internet of Things (IoT) target to attack resource-related things. It affects the memory, processing, energy, and battery of each node in the IoT environment. Existing protocols use complex mathematical calculations and additional control messages to detect the attacks. That consumes more energy for each node and reduces the lifetime of each node, also bringing the entire network to a halt. To overcome these problems the DE2RA-RPL protocol is proposed. It is a hybrid and lightweight protocol to detect and eliminate Destination Oriented Directed Acyclic Graph (DODAG) Advertisement Object (DAO) Flooding Attacks, Decreased Rank Attacks, and Increased Version Number Attacks at a time. The DE2RA-RPL protocol uses basic RPL control messages, a trickle timer, a minimum rank hysteresis objective function, and small byte flag values to detect and eliminate the attacks. This DE2RA-RPL protocol is suitable for smart communications systems that are used by police and military operations. The Cooja simulator, part of the Contiki operating system, simulates the proposed protocol. The simulation results are compared with existing protocols. It shows that the proposed protocol increases the Packet delivery ratio by 53.23% and Throughput by 59.74%, and decreases the Energy Consumption by 46.5% and, End-to-End Delay by 48.12% than the traditional RPL protocols.
