Mobile phone technology is going through revolutionary changes in last few years. As number of Smartphone is exceeding the number of desktops and personal computers, researchers are thinking of new ways to improve the capabilities of Smartphone’s. Key problems that researchers are trying to solve include isolation, vendor lock-ins, mobile cloud computing, and security, but the main issues are speed, QoS, security load balancing efficiency and hierarchy aware cloudlet. Signals generated by each mobile phone in the communication network are transmitted in the form of signals with help of transmitter and receive that signal with the receiver (OFDM). One of the most promising multi-carrier system, Orthogonal Frequency Division Multiplexing (OFDM) forms basis for all 4G wireless communication systems due to its large capacity to allow the number of subcarriers, high data rate and ubiquitous coverage with high mobility. When the signal is transmitted some noise is added with the original signal. If the value of noise is grater the value of PSNR will increase. To improve the efficiency of the smart phone traffic in this paper we used the chaotic communication to reduce the PSNR value in the signal while transmitting from the OFDM system.
