Figure 4 shows the traffic pattern only for the Facebook for 90 minutes without user interaction. From Figure 4 it seems that there are Idle gaps of several minutes between activity of Facebook application in the Android based smartphone. Also it seems that Facebook intelligently increases the gap between activities, if user is not using the phone, to save battery. It is also observed that the activity with Facebook starts after opening connection with Facebook Server and after data exchange for few seconds, connection is closed. Since the TCP connection is not persistence we didn’t observe Keep alive message.
