Performance Evaluation of Instant Messenger
Smartphone growths very fast since 2013, marked by the number of smartphone users reached ± 1.311.200.000 and continuously increase each year up to ± 300 million. In the early 2015 the growth of smartphones has reached ± 1.914.600.000[1].According to International Data Corporation (IDC) 2015, smartphones that dominate the world's market are Android and iOS. Android dominated the market with an 82.8% share in August 2015, followed by iOS with 13.9%, then the remaining 2.6% is held by Windows Phone, Blackberry and other smartphones [2].Recently, instant messenger is no longer a foreign mattertechnology in human society.

In design of any system Quality of Service (QoS) is one of the important issues from both customers and providers point of view that means customers expect the service of best quality from the system providers and providers want to give best quality of service to the customers from the system. Same in case of wireless communication systems. All the parameters related to QoS are having different importance for all customers and applications. The contentment level of different customers depends on different QoS parameters[5].The general quality of service (QoS) parameters most considered in the packet switched network are delay, packet size, and throughput [6].Quality of service (QoS) has a standard requirement for some primarily one-way of media data transfer/retrieval that is throughput should be less than 384 kbit/s or 384000 bit/s bps and delay should be less than 10 second [7].Based on the data above, the number of instant messenger is more than the number of smartphones itself that dominated by Android and iOS operating systems. However, according to DigitalTrends, these two operating systems ability are tend to be balance.
