DARPA’s Strategic Technology Office (STO) is focused on technologies that enable fighting as a network to increase military effectiveness, cost leverage, and adaptability. STO's areas of interest include: Battle Management, Command and Control; Communications and Networks; Intelligence, Surveillance, and Reconnaissance; Electronic Warfare; Positioning, Navigation, and Timing; and Foundational Strategic Technologies and Systems.

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.

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, and extensive unaffiliated commercial uses result in an increasingly congested, space, time and frequency environment. Severe pressure on available spectrum from all spectrum users creates a situation demanding significant adaptivity and flexibility of our communications systems to communicate successfully and achieve mission goals.

The electromagnetic (EM) spectrum is a scarce resource, in which a variety of friendly, unfriendly and neutral entities contend for available spectrum at any given time, location and frequency. DoD radio frequency (RF) systems, such as communication networks and radar, must operate within the context of an increasingly congested and contested electromagnetic spectrum.
