1.Return CONNACK instead of the broker when the gateway receives CONNECT while the client is Sleep or Awake mode. 2.Define the max size of a que for PUBLISH while the client state is Asleep mode. Despose packets when the que is full of packets. 3.Return PUBACK or PUBREL to the broker when the client is Asleep or Awake.
