Cooperative Communications for Improved Throughput, Range and Covertness
Conventional wireless communication systems are designed based on point-to-point links whose performance is limited by the resources of a single transmitter, e.g., power and bandwidth. Cooperative communications on the other hand is an emerging and actively researched class of techniques that enables nodes to in-crease their performance by harnessing resources from other local neighboring nodes. This paper presents a cooperative communications approach called Extended Communications using Helper Organizations (ECHO) that can increase throughput, communication range, and covertness. One militarily significant benefit, first identified and analyzed in this paper, is that cooperative communications approaches are difficult to geo-locate.
