    The IoT part is composed of an Access Point (AP), connected to several sensors using WIFI. In the
    system, the IoT part is considered as the part where the system data are created. In fact, the

    using the network part.
 
-** Network Part
    The network part is considered as the medium that link the IoT part to the cloud. It is composed
    of several network switches and router and it is considered to be a wired network.

+* System Model
+  The system model is divided in two parts. First, the IoT and the Network part are models through
+  simulations. Then, the Cloud part is model using real servers connected to wattmeters. In this way,
+  it is possible to evaluate the end-to-end energy consumption of the system.
+
+** IoT Part
+   In the first place, the IoT part is composed of several sensors connected to an AP which forms a
+   cell. It is model using the ns-3 network simulator. Thus, we setup between 5 and 20 sensors
+   connected to the AP using WIFI 5GHz 802.11n. All the nodes of the cell are setup with the default
+   WIFI energy model provided by ns-3.  The different energy values used by the energy model come
+   from the litterature and are provided on Table \ref{tab:wifi-energy}. Note that we suppose that the
+   energy source of the cell nodes are unlimited and thus every nodes can communicate for all the
+   simulation duration.
