Connectivity in a Rural/Suburban Scenario

Calculate the propagation results for a rural/urban scenario with 98 transceivers spread across a forest.

Model

The connectivity model represents the city of Stuttgart and a forest area around it. No buildings are modeled explicitly. The description files consist of topography (altitude) and clutter (land usage). This type of scenario is called a rural/suburban scenario in WinProp. The model is to be opened with CoMan (Connectivity Manager).

Nodes

There are 98 transceivers placed at random locations in the forest. The node density in certain clutter classes was specified whereby CoMan generated and distributed the nodes.

Air Interface

The multiple access scheme is set to CSMA/CA1 for mesh/sensor networks.
Tip: Click Project > Parameter to open the System Configuration dialog. Click the System tab to specify the parameters defining the air interface.
The available radio channels of the system are listed on the Channels tab.

Computational Method

The prediction method used in this model is the empirical two-ray model (ETR).
Tip: Click Project > Parameter to open the System Configuration dialog. Click the Prediction tab.

Wave propagation computation is computed for all the nodes by selecting Computation > Compute All > Wave propagation.

The next step is network analysis by clicking Computation > Compute All > Network.

Finally, connectivity is determined by clicking Computation > Compute All > Connectivity.

Results

Propagation results are computed for field strength and power for all the nodes and can be viewed at ConnectivityExampleRuralSuburban\results\propagation.

The connectivity between nodes can be viewed at ConnectivityExampleRuralSuburban\results\network. To view the connectivity between the nodes, activate Show Paths, and click on one of the nodes.
