Abstract : Typical future battlefield communication networks may consist of a moderate number of mobile radio nodes that broadcast on a common low-bandwidth channel. One can assume that the nodes will have high computing power, while the communications channel is slow and possibly noisy. In such a network, control of access times is necessary to avoid a breakdown of communications by colliding messages during times of high network traffic. To experiment with different control strategies and test their efficiency, a computer model of such a battlefield communication network has been developed at the U.S. Army Research Laboratory (ARL). The present report is a description of the model. The network traffic is modeled at an abstract level that permits the testing of the performances of various network access strategies and the assessing of effects of planned communication hardware. The model is coded in standard FORTRAN 77. When executed on a Cray supercomputer, it provides statistics about network performance typically in less than one percent of real time, that is, the modeling of one hour congested traffic requires a fraction of one minute on the computer. The model can be ported to any platform that supports FORTRAN 77.
