Performance Analysis of Wireless Propagation Model to Improve Signal Strength and BER for Wireless Mobile Network

Abstract

Abstract

Whenever we setup a network, environment properties such as fading, scattering etc. plays a very important role in choosing spectrum and method of propagation. The spectrum deals with frequency range suitable for communication in a particular environment, and the propagation method deal with channel selection, channel sensing and to perform quality communication throughout the network. To achieve quality output from the network, it is necessary to define network under different constraints. In this paper, a proposed constraints satisfaction problem (CSP) algorithm is used to communication in network through different propagation channel model. The    communication signal strength depends on the propagation channel model type used in the given network. Propagation channel model is also affected by the given environment and communication parameters. Three propagation channel model are Rayleigh propagation channel model, Friis free space channel model and Log normal channel model used for communication in the given network. Bit error rate (BER) and propagation loss is analyzed in different mobile network topology using proposed CSP algorithm.
