摘要：In Wireless communication, the average received power decreases logarithmically with distance. The main factor responsible for this is path loss, which represents signal attenuation as a positive quantity measured in dB. In this paper , we investigate the effects of noise level on various parameters such as Bit Error Rate (BER), Packet Success rate (PSR), Transmit Energy and total energy required to transmit eachinformation bits successfully. In this paper, energy metric is also derived which helps to calculate the optimal transmit energy
