Figure 2From: Optimal offline broadcast scheduling with an energy harvesting transmitterIllustration of DuOpt Flag. Illustration of the Flag and local optimizations, where all the feasible bits have been transmitted until the end of the fifth epoch; hence, a Flag is set to the fifth epoch pair, i.e., Equations 4 and 5. Energy minimization is performed upto epoch pair with the Flag, and time minimization is performed for the rest.Back to article page
