Fuzzy-Logic Control of Battlefield Communications

摘要

The basic communications network in a battlefield is a single low-bandwidth radiochannel that is used simultaneously by a small group of stations. In a modern Army environment, the nodes that share the radio channel will be computers that compose, encode, broadcast, receive, and display messages. Because the radio channel is used simultaneously by several nodes, one can expect collisions of messages, particularly during high combat activities. To reduce the number of such collisions, the access to the radio channel must be controlled. This report describes a control procedure that utilizes the computing power of the nodes and is based on fuzzy-logic rules. The control algorithm runs independently and concurrently in all participating nodes, making the control practically invulnerable. The control rules are designed to achieve and maintain high rates of information throughput, particularly under congested conditions. The control can be fielded using commercially available software or in-house developed programs.
