This paper proposes a low power real-time scheduling scheme that minimizes power consumption and reassigns polling order on the wireless sensor networks. The proposed scheme aims at enhancing the power performance based on the maximum constant power method along with the additional auxiliary schedule which can switch the primary one when a specific channel falls in a bad state or time slot is unused. Built on top of the EDF scheduling policy, the proposed scheme also tests whether an unused slot can be reclaimed without violating the constraints of subsequent real-time streams. To improve the probability of reclaimed bandwidth, it also rearranges the polling order. The simulation results show that the proposed scheme is able to enhance success ratio and it also provides minimized power consumption.
