A Changing legacy of Power grid systems into smart grid systems is becoming priority of many countries. This Optimization will be based on grid integrated real time communication between different grid elements in generation, transmission, distribution and loads. In automated metering infrastructure communication technology plays important role. This paper present analysis and comparison of five application layer protocols in the advanced metering infrastructure. The compared protocols are Zigbee 2.0, ANSI C 12.19, DLMS/COSEM, SML and IEC 61850. The protocols are compared with qualitative criteria, size of message and different binary encoding in protocols.
