In areas lacking trustworthy communications infrastructure, deployed servicemembers rely on wireless devices to perform double duty: they not only provide access to the network; they are the network. Protocols for these networks require nodes to coordinate among themselves to manage resources, such as spectrum and power, and determine the best configurations to enable sharing of information. A problem with these protocols is that they implicitly trust all information shared about the security and operational state of each node, and the network as a whole. Consequently, inaccurate control or security information can quickly render the network unusable. This shortcoming could put productivity and mission success at risk as use of military wireless systems increases.

DARPA published its Young Faculty Award (YFA) 2018 Research Announcement today, seeking proposals in 26 different topic areas—the largest number of YFA research areas ever solicited.
The continued growth in unmanned, sensor, and networked devices is expected to drive the need for larger, more capable and more diverse communications systems. Among other enhancements, these systems must improve jam-resistance and low probability of detection to keep pace with adversaries’ growing electronic sophistication and must adapt to fast-changing operational environments. By contrast, today’s military communications architectures are static and inflexible.
Defense forces rely on electromagnetic dominance for command, control, intelligence, surveillance, reconnaissance, and related applications that use the electromagnetic spectrum. Similarly, spectrum use by our adversaries, coupled with extensive commercial use, yields an increasingly congested space, time and frequency environment.
Commercial Test and Measurement equipment has advanced greatly with the emergence of sophisticated cellular and wireless local area network technology and can be used to intercept, analyze and exploit our military communications signals.
