DATA RATE REQUIREMENTS FOR RELAY LINKS IN VEHICULAR LOCATOR SYSTEMS

FOR THE EFFECTIVE USE OF MOBILE VEHICLES, A VEHICLE LOCATOR AND TRACKING SYSTEM IS NECESSARY. POSSIBLE USERS ARE POLICE, MUNICIPAL BUS SYSTEMS, TAXICABS, AND UTILITIES. ONE APPROACH OFTEN SUGGESTED EMPLOYS A NETWORK OF DISTRIBUTED SENSORS, WHICH SENSE AND IDENTIFY VEHICLES IN THE IMMEDIATE VICINITY. THE SENSORS RECEIVE TRANSMISSIONS FROM THE VEHICLES AND THEN PASS THE VEHICLE AND SENSOR IDENTITIES TO A CENTRAL FACILITY VIA A RELAY LINK. FOR THE RELAY LINK, MESSAGE-LOSS PROBABILITY AND TIME-DELAY STATISTICS HAVE BEEN GRAPHED AS A FUNCTION OF MESSAGE TRAFFIC. BY USING THE DUAL CRITERIA FOR ACCEPTABLE PERFORMANCE AS LOW MESSAGE-LOSS PROBABILITY AND SMALL TIME DELAYS, DATA REQUIREMENTS FOR UNIFORM VEHICULAR TRAFFIC HAVE BEEN OBTAINED. ENGINEERING ESTIMATES OF DATA RATE REQUIREMENTS FOR DIFFERENT SYSTEM CONFIGURATIONS CAN BE MADE BY USING THE FIGURES. THE PAPER WILL BE OF VALUE TO THOSE WHO ARE CONCERNED WITH IMPLEMENTING THE SYSTEM. /AUTHOR/
