Simple Agile RPL Multicast (SARCAST)

Denial of Service (DoS) attacks serve to diminish the ability of the network to perform its intended function over time. As DoS attacks may permeate the veil of the Internet of Things (IoT) devices from the broader internet, it is vital that these devices are able to mitigate these attacks. If such a network of IoT devices were to fail during time of need, lives of patients, war fighters, or the sustainability of manufacturing processes may be placed at risk. This work implements and provide initial assessment on a strategy to mitigate a resource exhaustion DoS attack using a network multicast service, wherein such an attack may target the critical energy reserves of low power devices. The Simple Agile RPL Multicast (SARCAST) concept implemented herein uses an agile addressing scheme to reduce the efficacy of multicast-based DoS attacks on IoT devices.
