Performance Analysis and Tuning of Coexisting Duty Cycling WiFi and Wireless Sensor Networks Conference Paper uri icon


  • © 2017 IEEE. Energy efficiency is of utmost importance for wireless networks due to the prevalent usage of mobile devices in WLAN and wireless sensor networks (WSNs). Consequently, duty cycling MAC protocols are widely employed in both WLAN (i.e., power saving mode - PSM) and WSNs (i.e., low power listening - LPL)). In a coexisting PSM and LPL network, a significant energy efficiency degradation has been observed because of large deviations of MAC protocol parameters from optimal values. To investigate these inefficiencies, analytical models are greatly preferred, when compared to simulation based methods, since they are faster, more scalable and can be used in optimization problems. Thus, this paper presents the first model for throughput and energy consumption analysis of coexisting PSM and LPL. Moreover, this paper presents a performance tuning method that minimizes the total energy consumption while satisfying the throughput requirements. Through extensive simulations, we demonstrate the accuracy of our proposed models and analysis. Finally, the proposed tuning method is evaluated, proving its effectiveness.
