Research on heterogeneous seamless handover has become popular, since the wireless networking systems were introduced with mobility. The typical current vertical handover mechanism consists of an architecture built at Layer 3 and implemented to serve for different technologies. Even though it has advantages in terms of simplicity, there still exist drawbacks such as the need of adaptation of the network architecture to different network technologies and systems. Providing transparency to the heterogeneous seamless handover can be provided by conducting the handover process at a higher layer. By that way, efficient handover decisions for vertical handover are made with more number of constraints that will lead to high performance, accessibility and low cost. Making this possible is by providing Quality of Experience (QoE) and obtaining current information of the throughput by measurements in the network. Analyzing and interpreting the statistics collected through measurements are vital in terms of decision making and to decide when to perform vertical handover. This thesis consists of the implementation of measurement module in two different approaches (Payload Dependent Approach and Payload Independent Approach) that will provide these statistics to the storage module in PERIMETER project.
