Energy Consumption Analysis for Wireless System using Stochastic Network Calculus

Green Power has been a hot topic in the field of communications. In wireless communication networks, transmission delay and energy consumption are always inversely proportional. In general, lower transmission rate consumes less energy, but a lower transmission rate leads to an increasing of transmission delay. Although a high transmission rate is possible to reduce transmission delay, it may lead to larger energy consumption. With the objective to minimize energy consumption under a certain transmission delay constraint, a wireless network model is proposed in this work. Then, the theory of stochastic network calculus is used to investigate the relationship among delay constraint transmission rate and energy consumption. In the end, the optimum solution of the optimization problem is achieved.
