Secure, private Internet and cloud to soldiers, marines at the tactical edge

cloud to grow and diminish as users move in and out of range of each other. Any connected collection of warfighters can store and share information in many places right at the tactical edge, making the system tolerant of communications disruptions. In essence, CBMEN creates secure frontline cloud storage services that provide content with decreased latency and increased availability.

The field tests proved the concept works and highlighted the potential benefits of real-time information sharing. At one point in the testing, two squads on foot patrol came within communication range of each other. One squad had information about a simulated person of interest that the other squad was seeking. The CBMEN software, working in the background on the troops’ mobile devices, automatically transferred the information from the first squad to the other, without the second squad having to ask for it. As the second squad entered a building where the person of interest was, the squad used that information to immediately identify and apprehend its target.

The testing also identified areas that need further development such as enhancing security and improving efficiency of information exchange, which will be the focus of the next phase of the program. The goal is to reduce the number of transmissions required, which would save power, and to also reduce the bandwidth needed.

A key factor that enables CBMEN is the tremendous computing power available in current mobile devices. “There’s more computing power and memory in my smartphone than the supercomputer I used in college,” Gremban said. “With 64 gigabytes of storage in a single smartphone, a squad of nine troops could have more than half a terabyte (500 GB) of cloud storage. CBMEN taps into that huge capacity.”

Beyond supporting troops on the frontlines, CBMEN technology may also be useful for civilian applications, especially disaster response, where the established communication infrastructure is unavailable or destroyed. Like forward-deployed troops with no established communications infrastructure, firefighters, police, medical personnel, National Guard members and others responding to a major disaster could quickly share imagery and vital information amongst each other.

Phase 2 of CBMEN program kicked off this month to mature the technology. The objective is to demonstrate improved warfighting mission support in a complex joint-content sharing environment between United States Marine Corps and Army networks using both military radios and commercial smartphone Wi-Fi capabilities.

“Content sharing, starting at the tactical edge, is changing the world in the way information can be shared for warfighters who need it most,” Gremban said.
