Abstract

Military requirements place a high premium on ultra-robust systems capable of supporting communication in extremely hostile environments. A major contributing factor in the survivability of systems is a high degree of redundancy. CSCR believes that the system designs offered below exhibit extraordinary redundancy features which should be of great interest to DARPA and the Department of Defense.

The Consortium for Slow Commotion Research (CSCR) [1] is pleased to

respond to your research program announcement (RFC 1216) on Ultra

Low-Speed Networking (ULSNET). CSCR proposes to carry out a major

research and development program on low-speed, low-efficiency

networks over a period of several eons. Several designs are

suggested below for your consideration.

1. Introduction

Military requirements place a high premium on ultra-robust systems

capable of supporting communication in extremely hostile

environments. A major contributing factor in the survivability of

systems is a high degree of redundancy. CSCR believes that the

system designs offered below exhibit extraordinary redundancy

features which should be of great interest to DARPA and the

Department of Defense.

2. Jam-Resistant Land Mobile Communications

This system uses a highly redundant optical communication technique

to achieve ultra-low, ultra-robust transmission. The basic unit is

the M1A1 tank. Each tank is labelled with the number 0 or 1 painted

four feet high on the tank turret in yellow, day-glo luminescent

paint. Several detection methods are under consideration:

(a) A tree or sand-dune mounted forward observer (FO) radios

to a reach echelon main frame computer the binary values

of tanks moving in a serial column. The mainframe decodes

the binary values and voice-synthesizes the alphameric

ASCII-encoded messages which is then radioed back to the

FO. The FO then dispatches a runner to his unit HQ with

the message. The system design includes two redundant,

emergency back-up forward observers in different trees

with a third in reserve in a foxhole.

(b) Wide-area communication by means of overhead

reconnaissance satellites which detect the binary signals

from the M1A1 mobile system and download this

information for processing in special U.S. facilities in the

Washington, D.C. area. A Convection Machine [2] system

will be used to perform a codebook table look-up to decode

the binary message. The decoded message will be relayed

by morse-code over a packet meteor burst communications

channel to the appropriate Division headquarters.

(c) An important improvement in the sensitivity of this system

can be obtained by means of a coherent detection strategy.
