Abstract :
In recent days intense research is taking place on energy efficiency (EE) of a multi-user wireless network. In this paper we propose a model to detect EE based on limited user traffic model. We observe the variation of EE against the number of users and energy signal to noise ratio engaged by the user. The impact of enhancement of subcarriers on EE and channel capacity is also analyzed to reach an optimum condition of network performance. Finally satisfaction index (SI) is plotted against signal-to-noise-ratio (SNR) for different bandwidth of subcarriers.
