Resource allocation is a protuberant, unavoidable feature for all future communication systems .It is important to maintain true communication between sources to destination without any loss. The Quality of Service (QoS) is also another important factor for any type of mixed and multi user communication. In this paper, OFDMA – SWIPT is considered for mixed traffic communication to data transfer and power (energy) gathering. SWIPT can be operated in two modes for data transfer and power calculation, those are Time Switching (TS) and Power splitting (PS). One of the methodologies for resource allocation can be done by using either PS-SWIPT or TS-SWIPT. By comparing PS-SWIPT and TS-SWIPT under various parameters like PAPR (peak to average power ratio), Channel state information (CSI), Quality of service (QoS), Bit Error Rate (BER) and TS-SWIPT system is best suited method. In this methodology the error rate becoming more, The present SWIPT system is best suited for limited users, if the number of users and mixed traffic is applied then Quality of service (QoS) will decreases. In proposed system, efficiency of the SWIPT OFDM system with Log-Normal function is analyzed. After adding Log-Normal distribution function if we use mixed traffic then QoS will be increasing, in simulation results it is proved.
