Abstract
Este procedimiento dirige las colisiones en un sistema de intercambio de datos entre objetos portátiles o placas, y al menos una terminal de emisionrecepcion de datos, o terminal, apta para cooperar con multiples placas simultáneamentepre sentes en el campo de accion de la terminal. Comprende lassiguientes etapas sucesivas: a) emision por parte de la terminal, hacia dichas multiples placas, de mensajes de llamada general con un parámetro de modulacionde probabilidad; b)emisioncondic ional por parte de la placa, hacia la terminal de un mensaje de respuesta a la llamada general con una probabilidad inferior a100% funcion del parámetro de modulacio de probabilidad en caso de colision, conteniendo este mensaje derespuesta a la l lamada general una identificacionpropia de la placa; c) contra recepcion por parte de la terminal de un mensaje emitido por otra placa, general y en ausencia de colision de este ultimo mensaje con un mensaje emitido por otra placa,establecimiento d e una conexion de comunicacion de datos específica entre terminal y placa y prosecucion delintercambio de datos, y retorno a la etapa a) para una nueva iteracion; d) en el caso contrario, retorno a la etapa a) para unanueva iteracion,eventua lmente con modificacion dinámica del parámetro de modulacion de probabilidad.
