Abstract:
The U.S. Air Force requires timely, reliable, and resilient communications in adversarial network environments. Within these dynamic environments, network nodes experience congested and contested spectrum with only limited and intermittent bandwidth available to support communications. Although there are many techniques that can be leveraged across the network protocol stack to improve communication reliability, resilience, and spectral efficiency, delayed and lost packets are inevitable in such environments. Thus, scheduling the right packets at the right time becomes paramount. The objectives of this project are two-fold. The first objective is to establish new priority- and deadline-aware scheduling solutions to ensure that the highest priority network traffic, defined in the context of the mission, is reliably delivered to its destination when it is needed. The second objective is to develop a framework to evaluate different airborne networking and communications protocols in the context of the overlaying command and control, intelligence, surveillance, and reconnaissance C2ISR applications. To meet these objectives, contributions have been made towards optimal priority- and deadline-driven scheduling, delay-sensitive medium access control based on carrier-sense multiple access with collision avoidance CSMACA, and the development of a framework that facilitates simulation-based and experimental airborne networking research and enables us to evaluate the effect of new communications and networking protocols on the mission itself. These contributions have been validated through a combination of simulation and experimental results.
