Algorithm 1. The strategy for each sensor to determine the optimal uplink transmit power
1:	Initially, sensor set the power level $x$ as 0, there is no energy transmission at the beginning of the game.
2:	for sensor $i\in N$ do
3:	Start game, initial parameters ${\tau }_i$,${\mu }_i$,${\eta }_i$ for the game;
4:	Based on the QoS requirements, set the final rate revenue level as $S_i$
5:	while $x_i>0$, do
6:	Calculate the optimal uplink power based on Equation (17);
7:	Calculate the optimal strategy of power level based on Equation (20);
8:	Calculate the maximized revenue for each sensor based on Equations (14), (17) and (20);
9:	Updata power level $x_i$ for each sensor;
10:	end while
