The focus of Internet of Battlefield Things IoBT is to provide situational awareness of the battlefield utilizing a network of interconnected sensors, actuators, and analytical devices. The US Army Research Laboratorys Tactical Network Assurance Branch developed a narrative of using IoBT to deploy multiple sensor nodes in an unknown or potentially hostile environment in which the system performs basic classification, identification of allies and adversaries, and inter-node communication via ad-hoc wireless network. Various types of sensors resulted in more robust classification due to multiple sensor data sources of complementary modalities. Sleeping algorithms extended sensor-node viability while maintaining network activity. Development of countermeasures to denial-of-service and distributed denial-of-service attacks were also explored in this work.
