Maximum Megahertz Project Case Study

Maximum megahertz project case study

In click here literature [turkmani] this gain has been evaluated as about maximum megahertz project case study dB per floor. This gain can be applied to all the indoor to outdoor communications and vice-versa.

In the implementation we considered three main possible scenarios which correspond to three standard deviations i. In case of transmissions from outdoor nodes to indoor ones, and vice-versa, the standard deviation has to be calculated as the square root of the sum of the quadratic values of the standard deviatio in case of outdoor nodes and the one for the external walls penetration. This is due to the fact that that the components producing the shadowing are independent of each other; therefore, the variance of a distribution resulting from the sum of two independent normal ones is the sum of the variances.

In case on NLoS several parameters scenario dependent have been included, such as average maximum megahertz project case study width, orientation, etc. The values of such parameters have to be properly set according to the scenario implemented, the model does not calculate natively their values. In case any values is provided, the standard ones are used, apart for the height of the mobile and BS, which instead their integrity is tested directly in the code i. In the following we give the expressions of the components of the model. We also note that the use of different propagation models OH, I, I with their variants in HybridBuildingsPropagationLossModel can result in discontinuities of the pathloss with respect to distance.

A proper tuning of the attributes especially the distance threshold attributes can avoid these discontinuities.

However, since the behavior of each model depends on several other parameters frequency, node heigth, etcthere is no default value of these thresholds that can avoid the discontinuities in all possible configurations. Hence, an appropriate tuning of these parameters is left to the user. The solution is to use only one propagation loss model i. While this gives a less accurate model in some scenarios especially below rooftop and indoorit effectively avoids the issue of pathloss discontinuities maximum megahertz project case study affects HybridBuildingsPropagationLossModel. The BuildingMobilityLossModel parameter configurable with the ns3 attribute system is represented by the bound string Bounds of the simulation area by providing a Box class with the area bounds.

Moreover, by means of its methos the following parameters can be configured: the number of floor the node is placed default 0. The BuildingPropagationLossModel class has the following configurable parameters configurable with the attribute system: Frequency: reference frequency default MHznote that by setting the frequency the wavelength is set accordingly automatically and viceversa.

Lambda: the wavelength 0. ShadowSigmaOutdoor: the standard deviation of the shadowing maximum megahertz project case study outdoor nodes defaul 7. ShadowSigmaIndoor: the standard deviation of the shadowing for indoor nodes default 8. ShadowSigmaExtWalls: the standard deviation of the shadowing due to external link penetration for outdoor to indoor communications maximum megahertz project case study 5. RooftopLevel: the level of the rooftop of the building in meters default 20 meters. Los2NlosThr: the value of distance of the switching point between line-of-sigth and non-line-of-sight propagation model in meters default meters. MinDistance: the minimum distance in meters between two nodes for evaluating the pathloss considered neglictible before this threshold default 0.

In order to use the hybrid mode, the class to be used is the HybridBuildingMobilityLossModel, which allows the selection of the proper pathloss model according to the pathloss logic presented in the design chapter. However, this solution has the problem that the pathloss model switching points might present discontinuities due to the different characteristics of the model.

This implies that according to the specific scenario, the threshold used for switching have to be properly tuned.

To run them, you need to have configured the build of the simulator in this way:. See the ns-3 manual for generic information on the testing framework.

You can get a more detailed report in HTML format in this way:. You can run each test suite separately using this command:. Several test cases are provided with different buildings having different size, position, rooms and floors and different node positions. The test passes if each every node is located correctly.]
