Evaluation of WPM-BPSK based peer-to-peer network using wavelets for different channels

In today's world high speed network plays a very important role for different applications. A peer-to-peer network satisfies the condition of high speed communication between nodes within the network. For efficient communication between nodes within the network multicarrier modulation technique needs to be employed. To achieve multicarrier modulation technique WPM (Wavelet Packet Modulation) is one of the promising technologies. In this paper WPM-BPSK (Binary Phase Shift Keying) system is used for evaluation of performance parameters of peer-to-peer network under different channels. To maintain the stable link between the nodes suitable wavelets are used in WPM-BPSK system. At lower values of SNR the performance of various wavelets is similar but results in significant change for higher values of SNR (Signal to Noise Ratio). The WPM-BPSK system is evaluated under different channel conditions like AWGN, Rayleigh and Rician for the parameters BER (Bit Error Rate) and throughput.
