The recent years, new mobile devices are becoming available in the market, that are equipped with multiple interfaces, such as mobile phones than can connect to 3G and 4G networks as well as to Wi-Fi hotspots. Thus, the increasing demands of the end users to connect to those networks anytime, anywhere, anyway (the ABC-Always Best Connected principle), has led to the development of a standard that can provide all the needed mechanisms to accomplish a seamless handover between heterogeneous systems. This thesis aims to study the IEEE 802.21 Media Independent Handover protocol and the basic elements of it. In particular an external study on the protocol is carried on, as well as the way that its elements interact through the handover initiation and preparation phase. Finally, we provide some examples of the messages that are transmitted between the network nodes, so as to accomplish the handover execution, based on the 802.21 protocol.
