Modeling and simulation of fading, pathloss, and shadowing in wireless networks

To explore and simulate the influence of multipath fading, pathloss, and shadowing fading on wireless networks, this paper creates mathematical and simulation models for multipath fading and shadowing fading, designs an approach to calculating the shadowing effect, and optimizes the utilization of the pathloss exponent. Moreover, modeling and simulation are implemented with a simulation software-OPNET for demonstrating the above work. Simulation results quantitatively show the impact of these effects on throughputs and communication ranges of IEEE802.11a/b/g wireless networks. These results are consistent with present documents and theoretical analysis, thus simulation of wireless networks become more accurate and reasonable. Simultaneously, the simulation platform used in our research is also improved by integrating new models.
