Troops operating in forward locations without telecommunication infrastructure often rely on a mobile ad hoc network (MANET) to communicate and share data. The communication devices troops use on foot or in vehicles double as nodes on the mobile network. A constraint with current MANETs is they can only scale to around 50 nodes before network services become ineffective. For the past 20 years, researchers have unsuccessfully used Internet-based concepts in attempts to significantly scale MANETs.

Squads of Soldiers or Marines on patrol in remote forward locations often don’t have the luxury of quickly sharing current intelligence information and imagery on their mobile devices, because they can’t access a central server. Troops frequently have to wait until they’re back at camp to download the latest updates. In the meantime, mission opportunities may erode because the information needed at the tactical edge isn’t immediately available.

Establishing long-range tactical communications for U.S. troops in remote locations currently requires giant parabolic dishes, tall pole-mounted antennas, large antenna domes, and high-power amplifiers. Besides their significant weight, power, and cost (SWAP-C), these antennas present large visual and radio frequency (RF) signatures, are vulnerable to jamming, and constitute a single point of failure.

Information, or ‘content’, on the World Wide Web is replicated and distributed across the world to ensure high availability to the end-user. User expectations for rapid access to content have led to the creation of content distribution systems that enhance the user experience. Consequently, users may quickly access content used for everyday living, from restaurant menus and maps, to local and world news.
