Aradaki koordinasyonu ise bir MQTT Broker \u00fcstlenir. Bu mimari, cihazlar\u0131n do\u011frudan birbirleriyle ileti\u015fim kurma ihtiyac\u0131n\u0131 ortadan kald\u0131rarak mimariyi basitle\u015ftirir ve esnekli\u011fi art\u0131r\u0131r.<\/p>\n<p>MQTT, farkl\u0131 “Hizmet Kalitesi” (Quality of Service – QoS) seviyeleri sunar, bu da geli\u015ftiricilere mesaj teslimat garantisi konusunda esneklik sa\u011flar:<\/p>\n<ul>\n<li><strong>QoS 0 (At Most Once):<\/strong> Mesajlar en fazla bir kez g\u00f6nderilir, teslimat garantisi yoktur.
